Preparation BI-58, overview of the features of the insecticide BI-58

Precautions when using Bi-58 - harmfulness of the product

If you use the new drug Bi 58, the instructions for use must be followed exactly.
It, in particular, contains information about safety measures, and the first warning concerns health safety for summer residents - for the preparation of Bi-58 it is recommended to use technical containers that in the future will not be used for storing food, it is advisable to protect your hands with gloves, your body - thick clothes. It is recommended to spray the plantings while wearing a respirator and glasses so that the solution does not get on the mucous membranes of the nose, eyes, mouth, and if there are open bodies of water near the site (within a kilometer radius), it is not recommended to use Bi 58, since the chemicals are dangerous for aquatic life.

Bi-58 belongs to the category of highly effective insecticides that, when used in accordance with the instructions for use, do not harm the environment. To avoid unpleasant consequences, carefully read the instructions before you start using the drug in your summer cottage.

In summer and spring, agricultural crops are susceptible to attack by various insect pests. Parasites damage the plant mechanically, infect it with viruses, and also create a favorable environment for the emergence and development of various diseases. All this leads to the death of bushes. To protect green spaces, gardeners use pesticides. One of the popular ones is BI-58. What this drug is, how to dilute BI-58 and how to carry out processing - the article will tell you about all this.

Advantages and disadvantages

The drug Bi 58 has proven itself to be a highly effective and reliable product. It has several advantageous differences from other insecticides. These include:

Wide spectrum of antiparasitic action. Bi 58 and modification Bi 58 New are active even against insects that are resistant to other pesticides.
Compatibility with other chemicals for the care of agricultural and ornamental plants. It can be used simultaneously with fungicides. Not recommended for use with alkaline products.

Bi 58 can be used in combination with other drugs against herbivorous insects
No toxic effects on plants.
Wide range of temperatures at which the product can be used.
Very quick effect of use.
Possibility of spraying plants with the drug throughout the growing season. However, 3-4 weeks before the start of harvest, the use of the insecticide should be stopped.
Moderate cost compared to other insecticides.

Like all chemicals, insecticide Bi 58 also has some disadvantages. These include:

strong unpleasant odor;
there is a high risk of harming the plant if the dosage is violated. Although formally the drug belongs to the third class of danger poisons, experienced plant growers tend to classify Bi 58 as a second class;

When using Bi 58, there is a high risk of harming the plant by violating the dosage

Difficult to use in enclosed spaces with poor ventilation. When treating indoor flowers, it is better to use softer products;
danger to pollinating insects and fish;
the possibility of skin reactions and irritation of mucous membranes when working without personal protective equipment.

The insecticide is mildly toxic to humans and warm-blooded animals, but should be used with caution.

Application of Bi 58

Instructions for use of amistar extra fungicide and method of preparing the solution Preparation
Bi 58 can be used throughout the entire growing season of cultivated plants, with the exception of the last 40 days before harvesting. Pest eggs sometimes remain viable after a single pesticide treatment, so if the plantation is heavily infested with parasites, spraying must be repeated after 2 weeks. The Bi 58 solution prepared according to the instructions is used for the following crops (consumption is indicated for 1 hectare of agricultural land):

Plant	Its pests	Required amount of drug in liters
wheat	1,5
barley and other grains	1,0–1,3
potato	nematode, Colorado potato beetle, wireworm	1,6–2
roots	tick, fatty leg	0,5–1
pulses	weevil, codling moth, aphid, pea weevil	0,5–1
fruit trees	caterpillar, moth, scale insect	0,8–2
raspberries	galitza, cicada, tick	0,6–1,2
grape	wood borer, leaf roller, aphid	1,2–3

How to dilute and use the drug Bi-58 - dosage

To dilute the Bi-58 solution, the new instructions for use advise preparing and applying according to a single standard to destroy all types of insects damaging plantings:

One ampoule dissolves in 5 liters of slightly warmed water (+20°C, no more);
The working solution is mixed until homogeneous and poured into the sprayer immediately after preparation;
The instructions recommend treating plantings at air temperatures above +20°C, but below +28°C, since in this range the effectiveness of the insecticide reaches its maximum values.

The new consumption rate of Bi-58 is lower than that of other insecticides, and the effect lasts up to 20 days. When planting potatoes, up to 2 liters of working solution per hundred square meters are used, and Bi-58 is used in even smaller volumes for cabbage, beets, cucumbers and other crops - up to one and a half liters per hundred square meters. To treat shrubs (raspberries, gooseberries, currants and others) use up to 1.2 liters per hundred square meters, and for each fruit tree use up to 3 liters of ready-made Bi-58 solution.

The number of treatments depends on the number of pests in the dacha area. Regarding the use of Bi-58 in ampoules, the instructions for use contain recommendations for double use with an interval of 2-4 weeks, while it is advisable to treat trees in the garden during the formation of buds (3 weeks before flowering, so as not to harm beneficial insects) and after formation of ovaries, and beds with vegetables and ornamental plantings are sprayed for the first time when pests appear, and again as needed.

Summer residents who have tried Bi-58 on their plots claim that it is better to use the product immediately after germination, and the number of treatments over the summer can reach up to five. At specialized dacha forums, gardeners share that with this scheme of using Bi-58 for the next season, pests are completely absent from the site, but there is also a certain danger in this, because beneficial insects also disappear from the site, which negatively affects the yield.

Is it possible to be poisoned by “Bi-58”: precautions

Coragen, ks

"Bi-58" is a very toxic insecticide for bees and aquatic organisms, but if you strictly follow the instructions, the danger can be avoided. For warm-blooded animals, such as rats, the poison is moderately toxic (LD 230 mg/kg)

It does not pose a threat to humans if precautions are taken. Otherwise, it may provoke a cumulative, skin-resorptive reaction, burns and severe poisoning.

The active substance causes general weakness, drowsiness, nausea and vomiting, constriction of the pupils, impaired coordination of movements, and severe sweating. If you notice the following symptoms after working with an agrochemical, immediately consult a doctor for help. Do not waste time, because under the influence of the drug the function of cholinesterase, an enzyme that signals nerve impulses, is inhibited. Subsequently, cardiovascular imbalance and loss of consciousness are possible.

In such situations, before the doctor arrives, you need to take a solution of crushed activated carbon at the rate of 3-5 tablespoons per glass of water and induce vomiting.

A significant “minus” of the insecticide is the strong unpleasant odor of the substance, therefore, when using “Bi-58”, proper dosage and protective equipment are important. All work, including preparatory work, should be carried out in special clothing, safety glasses, rubber gloves and boots, as well as a hat. It is strictly forbidden to eat, smoke or drink alcohol at the same time. It is also recommended to limit contact between hands and face as much as possible.

It is unacceptable to pollute sources, reservoirs, and wells with solution residues. Also, you should not disinfect near them and pour out water after cleaning containers and equipment contaminated during operation. The backpack sprayer is washed daily, re-treating the crop with plain water. Empty containers after agrochemicals must be burned without inhaling smoke and released particles.

During the spraying period and after it, livestock grazing is not allowed in the treated area. Also, within a radius of 4-5 kilometers, the flight of bees is limited for 120 hours.

Be attentive to your well-being. If poison gets on the skin, remove it with cotton wool without rubbing it in, then rinse with running water or a weak soda solution. If the drug gets into your eyes, rinse them with plenty of water for 15 minutes. In case of swallowing and irritation of mucous membranes, consult a doctor

It is important to keep the insecticide packaging label

Make sure that spraying occurs away from children and pets. Pesticide poisoning in cats is manifested by tremors and drooling, and in rabbits the neck muscles weaken.

Composition and action

DV Bi-58 dimethoate (formula in the figure on the right) belongs to the chemical class of organophosphorus compounds (OPS). The mechanism of action is a nerve poison (neurotoxin) that blocks the enzyme-mediator cholinesterase. The result is failure of nerve impulses to reach the muscles, convulsions, paralysis and death.

Chemical formula of dimethoate, the active ingredient of the Bi-58 pesticide, and its structural model

Toxicology

Like other neurotransmitter (transport enzyme) blockers, dimethoate is a rather slow but very strong poison. It is weakly selective towards taxonomic groups of animals, because Cholinesterase is a universal mediator of nervous control of muscles. The toxicity of dimethoate for warm-blooded animals increases with increasing metabolic rate, so working with Bi-58 in hot weather requires additional precautions, and for birds this pesticide is almost less dangerous than for the objects being eliminated. Also - for fish and aquatic organisms due to good solubility in water (39 g/l); the same factor determines the environmental hazard of the drug in rainy weather.

For humans, Bi-58 is especially dangerous in case of inhalation (inhalation) of splashes of the working solution (this is what causes accidents in agricultural production) or contact with mucous membranes. Inhalation of vapors is less (but still very) dangerous, because The volatility of the additive is low (0.107 mg/cubic m at +25 degrees Celsius). It is also very dangerous if the drug gets on the body, because it is quickly, within a few minutes, completely absorbed into the body through dry, intact skin (through mucous membranes - instantly). Toxicological indicators of dimethoate are close to threatening:

LD50 for rats 230 mg/kg body weight; for mice 135 mg/kg;
ADI for humans is 0.002 mg/kg.
TAC in soil is 0.1 mg/kg.
MPC in water of reservoirs is 0.003 mg/cubic meter. dm social-t.
The maximum permissible concentration in the air of the working area is 0.5 mg/m3. m.
MPC in atmospheric air is 0.0003 mg/cubic meter. m s.-s.

Note: the content of dimethoate vapor in the air is 10 mg/m3. m is 100% lethal for rats, and 3 mg/cu. m for most laboratory animals. The lethal dose of dimethoate applied to the skin of mammals ranges from 1-1.5 g/kg.

Acute poisoning with dimethoate develops gradually, over 1-3 days. Initial symptoms are general weakness and drowsiness. Then you feel chills, nausea, vomiting, and profuse sweating begin. In case of moderate poisoning, this is followed by tremors, loss of coordination of movements, a wobbly “drunk” gait, and constriction of the pupils. In case of severe poisoning, clonic convulsions begin, turning into local paralysis, then a coma is observed. Death occurs due to impaired cardiovascular activity. There is no specific antidote, treatment is symptomatic.

Application procedure

Aktara: instructions for use for different plants

The preparative form of EC requires preliminary preparation of a stock solution (dose of the drug per 0.5-1 liter of water). First, the sprayer tank is filled 2/3 - 3/4. Then water-soluble substances are introduced into it (if a mixture is used). Then, without delay, prepare the mother liquor with continuous stirring. It is necessary to dilute Bi-58 and pour the “uterus” into the tank quickly, because The shelf life of the drug in the open air and in the mother solution is no more than 10 minutes. Next, add the remaining components (if necessary) and get to work. The device must be filled in no more than 4 hours.

Spraying is carried out according to the usual rules: from early morning on dry plants or in the evening at sunset, because Dimethoate is photolytic. For the same reason, the weather is highly desirable: cloudy, but without precipitation. The time before rain is until the next morning, but not less than 12 hours.

Instructions for using insectoacaricide on agricultural farms are given in the table:

Cereal grain, food potatoes, sugar beet, table and fodder beet, rapeseed (grain, oil) – 0.05.
Pulses – 1.0.
Cabbage – 0.2.
Tomatoes, cucumbers, melons, pome fruits, berries (including grapes), rice, millet, sunflowers and corn (grain, oil), soybeans (beans, oil), fruit juices and wines, olives (fresh, pickled, olive oil), mushrooms, dry hops, tobacco – 0.02.
Stone fruits – 2.0.
Citrus fruits – 5.0.

Application in private household plots

Bi-58 is not registered for use in private household plots in the Russian Federation, but is sold in small packaging (ampoules, see figure) and is quite in demand among small private farmers.

Drug Bi-58 of dubious origin

Among them there is a widespread belief that a significant proportion of the “ampoule” Bi-58 is counterfeit, and they have even developed a system for recognizing the “real” one, see video:

Video: identifying an obviously fake Bi-58

In such a case, rest assured: BASF Bi-58 does not produce small packaging, DV does not sell it separately, and does not have partners who repack the finished product. Considering the short shelf life of the opened drug in air, the effectiveness of Bi-58 ampouled using homemade methods is unpredictable, even if the agrochemical dodgers do not dilute it. We can only say for sure that this “ampoule” insecticide is less effective than the original one.

However, amateur gardeners quite actively use Bi-58 against aphids and other pests of berry bushes. The drug is used even on crops that accumulate “chemistry” well, such as raspberries, see next. plot:

Video: processing raspberries Bi-58 (!?)

However, the MRL in berries from treated bushes is unlikely to be checked, and if so, it is probably exceeded. In private household plots, Bi-58 is, in principle, applicable to fruit trees and grapes in this way (the regulations are not normative!):

Is it possible - on a room-by-room basis?

In residential premises, the insectoacaricide Bi-58 is clearly not applicable - dangerous inhalation of household members is guaranteed. However, many indoor gardeners take their potted plants out onto the balcony in the summer. For some indoor crops, this is the only opportunity to improve their health for the winter. But outdoors, pampered plants become easy prey for pests. The ampoule helps, see for example. video:

Benefits of insecticide

"BI-58" has a number of advantages over other insecticides:

It is in a liquid state, due to which it begins to act faster (the results of the treatment are visible immediately after 3-5 hours).
An hour after spraying, it is not washed off by precipitation.
A fairly long period of protection - from 15 to 20 days.
The insecticide substance combines well with other drugs against pests, so it can be used for complex spraying of plants (with the exception of poisonous substances with an alkaline environment and/or which contain copper. Since in an alkaline aqueous environment the main substance of the insecticide is hydrolyzed, and as a result this the substance is destroyed).
Wide range of crops that can be processed (cereals and legumes, fruit trees, root vegetables and cruciferous plants).
Effective against various types of pests.
The drug has not only an insecticidal, but also an acaricidal effect.
Not phytotoxic.
Wide temperature range of application.
The drug allows you to choose the optimal consumption rates.
"BI-58" has an affordable price.

Storage conditions

The safety data sheet contains the following criteria for storing the drug:

temperature limits - from minus 10 to plus 25 degrees;
shelf life in warehouses is 24 months;
the protective abilities of the drug are not guaranteed when heated or exposed to direct sunlight;
the properties of the insectoacaricide are lost when the permissible storage period is exceeded.

The manufacturer warns that the drug should be stored:

where accidental access by children and animals is excluded;
within the specified temperature limits;
in a ventilated area;
in warehouses equipped with a grounding system.

Used containers are disposed of in accordance with hazardous waste requirements.

Advantages of insecticide BI-58

Insecticide BI-58 is in liquid form, so it works faster than its analogues. The results of its work are noticeable within 3-5 hours after treating the plants. At the same time, it is not washed off by precipitation within an hour after spraying. The effect of the drug is limited to a period of 15-20 days. The formula of the insecticide BI-58 combines well with a number of other drugs, so it can be used in complex treatment of plants. The exception to compatibility is toxic substances with an alkaline environment or the presence of copper in their composition. The list of plants treated with the drug includes grains and legumes, fruit trees, cruciferous plants and root vegetables.

Systemic action - the drug is absorbed by plant parts and then distributed throughout the plant, mainly acropetally. Sucking insects die due to feeding on plant sap. Thanks to the high systemicity and uniform redistribution of the active substance within the plant, protection of the newly growing parts of the plant from harmful insects is provided.

Contact action – a pronounced contact effect on insect pests located on the surface of the plant at the time of treatment. Actively acts through the integument of the insect.

Preparation of working solution

Fill the sprayer tank with water to 2/3 of the volume and slowly add the required amount of the drug. Mix the working solution by turning on the sprayer mixer. Bring the volume of working fluid to the required volume and turn on the mixer again for 10-15 minutes. The prepared working solution should be used immediately after preparation.

Who and why allowed children to be re-poisoned with a dangerous insecticide

36 students of the lyceum in the village of Kuizauca, Rezina district, were again poisoned by the toxic chemical BI-58, because after the first emergency no one bothered to decontaminate the building. The consequences of the poison are comparable to the consequences of using poisonous gases such as sarin. Meanwhile, BI-58 is distributed freely, no one controls its circulation, the situation can repeat itself at any time anywhere - in transport, in a supermarket, on the street.

An examination by the National Center for Public Health confirmed that students of the lyceum in the village of Kuizeuka, Rezinsky district, were repeatedly poisoned by the insecticide BI-58.

The first emergency occurred on March 3: according to the prosecutor's office, a student carelessly broke a bottle of BI-58 in the school assembly hall. 14 schoolchildren were taken to the district hospital, and later to the Republican Institute of Mother and Child. Three girls were in serious condition. It would seem that all this should have alarmed those in charge. Nothing like this! Everyone calmly went to celebrate March 8th. After the holidays, another 36 students were poisoned. 34 children remain in the district hospital, two were transported to Orhei. Lyceum students are recovering, detoxification therapy will continue until symptoms disappear completely. But who will give children a guarantee of a complete recovery after such severe poisoning? Poison that was banned

The drug BI-58 is widely distributed in the post-Soviet space. Moreover, until 2004 in Russia it was classified as an emergency - first - class of hazard poison with limited access: it was assumed that only specialized services could work with the toxic chemical, subject to the use of protective equipment: special suits, respirators, etc.. As a result, BI- 58 was banned altogether. After which it strangely rose from the ashes like a Phoenix bird: it was registered as “BI-58 new”, changed its hazard class and is still sold without any restrictions - even on the Internet.

Being a systemic drug, BI-58 penetrates inside the plant, dissolves in its juice and contributes to the death of insects and mites that feed on these juices. The instructions say that the pesticide is “well tolerated by plants, has a general and contact effect, i.e. actively affects the insect even through its integument.” However, specialized resources report that professionals do not like BI-58 because of its extreme danger: even plants do not always tolerate it, let alone humans, mice run away from it, and bees die en masse. What are the risks of contact with pesticides?

All organophosphate pesticides are deadly. However, in the case of BI-58, restrictions formally apply only to children, pregnant and lactating women, people who have suffered severe infectious diseases or surgical operations (within a year). However, if BI-58 enters the body with food, it will result in a very severe defeat even for a healthy and strong man. If a person working with poison drinks alcohol, the toxic properties of BI-58 will increase, and the threat of damage to the liver and nervous system will increase significantly. If the pesticide enters through the respiratory system (in the form of vapors, dust, small drops) it can cause cardiac arrest. People who previously regularly treated plants with BI-58 vomit at the slightest smell. If a person has regularly used BI-58 for a year (at least once a month), he may begin to experience heart pain and migraines, and irreversible vascular disorders may appear.

BI-58 and the poisonous gas sarin have the same basis. Sarin itself was discovered by German scientists during experiments to create more powerful pesticides. In 1993, in Paris, 162 UN member states signed the Chemical Weapons Convention, which prohibits the production and stockpiling of many chemicals, including sarin. The document came into force on April 29, 1997, after which the complete destruction of all stocks of chemicals specified in the list continued until 2007. But other organophosphorus substances are sold freely! What needed to be done

Only after repeated poisoning did the Prosecutor General’s Office open a criminal case under Article 224 of the Criminal Code (Part 3) – “Violations of the rules for storing and transporting pesticides or other chemicals, which led to the creation of a dangerous situation that caused heavy damage to public health.” The prosecutor's office believes that officials did nothing to eliminate the consequences of the accidental distribution of toxic substances and allowed students to attend classes. According to the inspection, during renovations, the ventilation in the lyceum was shut off, and the poison simply could not ventilate. They just washed the floors at the lyceum! The chemical was absorbed into the walls, floor, ceiling and was waiting for new victims.

The headmistress of the lyceum, Raisa Teut, cowardly quit after the tragedy; her deputy, Vasily Birca, who remained on the farm, believes that everything is fine: before the start of the school year, a special commission checked the premises and gave the go-ahead for the opening of the school on September 1. “I think the ventilation system is working,” the teacher thoughtfully told the Public TV channel. “It cannot be closed.”

Health Minister Ruxanda Glavan signed a decree on Wednesday dismissing the head of the regional public health center, Ion Ceptine. He immediately went on sick leave, but Prime Minister Pavel Filip said that this would not save the official: he would leave his post after he recovered.

Meanwhile, information about the first emergency was disseminated by the media - which means that the head of the general department of education, youth and sports of the Rezina district council Lidia Lazar, the district prosecutor Andrei Roshka, and the head of the district council Eleonora Graur could and should have intervened. In the end, everything was blamed on teachers and the public health center. Although they are clearly to blame. The simplest common sense should have dictated a number of actions to the director, most importantly, it was necessary to notify the head of the Department of Civil Protection and Emergency Situations of the Orhei region, Lieutenant Colonel Iulian Sangereanu (this structure serves the Rezina region). Special services could declare a state of emergency in the lyceum, assess the risks and carry out decontamination. Instead, the lyceum workers themselves ineptly started cleaning, putting their health and the health of their children at risk. The most popular insecticide about which little is known

But do other teachers and health doctors know, do we all know how to behave in such situations? The problem is that the dangerous insecticide BI-58 and similar substances have been sold on Moldovan markets absolutely freely since 2010 - both in original plastic packaging and in counterfeit glass; repackaging the poison is prohibited. According to the producers, official import and distribution are allowed to four Moldovan companies, and the sales permit is issued for seven years.

The cheaper the insecticide, the more harmful it is: it decomposes more slowly, and the more actively affects human health. BI-58 is one of the cheapest, and therefore the most popular. It is even used to process berries! Meanwhile, people know very little about this insecticide. The instructions say that the drug decomposes within a month, on specialized sites - within four months, and in enclosed spaces it does not erode even after two years. According to some specialized resources, BI-58 is generally only suitable for processing non-food crops - forests, parks, cotton plantations, as well as seed plots.

BI-58 smells like kerosene infused with garlic. Even when processed outdoors, the toxic chemical literally knocks people off their feet. On June 20, 2012, in the Bolgradsky district of the Odessa region, workers at the Suvorov experimental production farm were poisoned: the victims were tying up grapes, while at a distance of 200 meters from them, eight people were treating the plantations with Bi-58. 45 people were taken to the hospital, 36 were hospitalized, three were in the intensive care unit. The case was investigated by a special commission. The root of the problem: the circulation of toxic substances should be limited

We talked about the dangers of BI-58 with many doctors, including sanitary ones, and everyone was against the newspaper referring to them. This is eloquent evidence of the climate of general fear that is created in our country around any emergency situations, when the authorities are zealously looking for the extreme, without thinking about the root of the problem. And the root is, and this is what doctors unanimously say, that the circulation of poisons such as BI-58 must be limited. But even if such a bill is developed, it is unlikely that parliament will pass it: everyone knows who is engaged in business related to the import and sale of insecticides.

The country has worked long and hard to create the tourism brand of Moldova, which is based on Moldovan wine, fruits and vegetables, tasty and safe. We all believe this. In the markets, consumers unanimously demand their own, Moldovan products, not trusting imported products. But it turns out that native “healthy” vegetables and fruits are treated with the primitive pesticide BI-58, and under what conditions! There are no guarantees that peasant farms know how to properly treat gardens, berry and vegetable plantations, in what time frame the insecticide decomposes, and there is no confidence even in the correctness of the instructions for deadly poisons.

Previously, every collective and state farm had an agronomist for plant protection - a responsible person; there were means of protection for those using pesticides. Now the poisons themselves are certified, there is a special structure that deals with this, but to work with chemicals and fertilizers you don’t need a license, you don’t need special knowledge: buy and spray with a broom from a bucket, and then sell on the market, especially since you also need to purchase a sanitary certificate no problem. To make poisons even cheaper, they are packaged in glass bottles, which peasants then drag from the market, and there is no guarantee that all this will not break on a minibus, on a bus, in a station building, in people’s homes, or anywhere else. In specialty stores and warehouses, salespeople and other workers breathe poisonous air all day long, and no one cares. So where will we get the health of the nation? In the photo: Although the dangerous toxic chemical BI-58 in Moldova can only be sold in plastic containers, on the Moldsem Grup website - Moldsem.md it is offered to customers in glass ampoules. It was these ampoules that broke in the rural lyceum of the Rezinsky district.

Precautions when using Bi-58 - harmfulness of the product

It is recommended to spray the plantings while wearing a respirator and glasses so that the solution does not get on the mucous membranes of the nose, eyes, mouth, and if there are open bodies of water near the site (within a kilometer radius), it is not recommended to use Bi 58, since the chemicals are dangerous for aquatic life.

Contact with plants treated with the drug is allowed no earlier than after 2 days in closed ground, and in open ground - only after 4 days. Potato and grape plantings treated with an insecticide solution are recommended to be treated after 3 weeks, and before this period, the plants are cared for with gloves and the body is protected with thick clothing. On fruit trees, toxins last longer - about 30 days. Bi-58 belongs to the category of highly effective insecticides that, when used in accordance with the instructions for use, do not harm the environment. To avoid unpleasant consequences, carefully read the instructions before you start using the drug in your summer cottage.

Special instructions and precautions

When using Bi 58 to protect plants from pests, the following safety precautions must be observed:

All work on preparing the working solution and using the chemical must be carried out in closed shoes, a suit, rubber gloves, a respirator and safety glasses.

“BI-58 New” - instructions for use taking into account all the dangers

Despite such a wide range of effects of the pesticide, it is very harmful and dangerous for humans, bees, fish and warm-blooded animals. Therefore, they are prohibited from spraying flowering plantings, otherwise they could destroy their apiary. In addition, it is recommended to carry out the last processing of the land 30 days before the start of harvest. At the same time, you should avoid getting the chemical into ponds or other water sources.

In enclosed spaces, it is planned to treat plants no more than 2 times a year: in spring or at the end of summer. After the procedure, be sure to ventilate the room.

Many gardeners are interested in when to spray their plants with the BI-58 insecticide. According to the instructions, this is done during the growing season, as well as at a temperature of +20-28˚С. Under such conditions, the effect of active substances reaches its maximum value.

The dosage of the working solution for each crop is as follows:

Grape. The pesticide will need 1.2-2.8 liters per 1 hectare of planting or 10 liters per 30 m². The waiting period is a month.
Potatoes - 2 l/ha, up to 20 days.
Vegetable crops - 500-900 ml/ha.
Pear and apple tree - 2-5 liters of solution per tree. Treatment is carried out before or after flowering. The effect is observed for 40 days, as indicated in the instructions for use “BI-58 new”.
Raspberries, currants and gooseberries. There is up to 1.2 liters of solution per hundred square meters.
Sugar beet - 0.5-1 l/ha per month.
Winter wheat, oats, rye and other cereals - 1-1.5 l/ha with effect for up to 30 days.
Ornamental/indoor plants and shrubs - 1 l/m².

With the exception of apple and pear trees, spraying is recommended during the growing season. The maximum number of treatments is 2 times per season. The interval between them is the waiting period indicated on the package. For different crops it lasts 20, 30 or 40 days.

Don't forget about precautions. Goggles, gloves, mask and tight-fitting clothing/gown must be used

After pickling, be sure to wash your hands (up to the elbows) and face with soap.

How to dilute the drug “BI-58 new”

The preparation of the solution largely depends on the degree of infestation of the planting, the “appetite” of the pests and the type of crop. Manufacturers usually indicate on the packaging how to dilute “BI-58 new”. Basically, for 10 liters of liquid, in rare cases for 20 liters, you will need 10 ml (2 ampoules) of the chemical. To combat mole crickets, agronomists advise applying the insecticide directly to the soil.

When planting tubers, seedlings or seeds, prepare bait:

fry corn, grains, dirt or mixed feed (up to 6 kg);
10 ml of the drug is mixed with aromatic food;
leave to infuse for 2-3 hours;
during planting, they are embedded in the soil to a depth of 3 cm.

To prepare the solution you need soft water. Impurities of clay or other rocks lead to modification of the concentrate. Moreover, experts recommend heating the liquid to 20˚C.

It is worth noting that the shelf life of “BI-58 new” is no more than 2 years. Store the container with the drug in a dry and fairly cool place. It is noteworthy that 1 liter of this liquid contains 400 ml of a toxic substance. For this reason, the emulsion is hermetically sealed and packaged in a bag or box. Keep it away from children, food and fire.

Having examined the instructions for use of the new generation “BI-58”, you can see that this is a very poisonous insecticide. The consumption of the product depends on the degree of plant infestation. The pesticide (2 ampoules of 5 ml each) is diluted in 10 liters of soft and slightly warmed water. A spray bottle is used for spraying. Repeated treatment is planned in 30-40 days. Using this insecticide to treat insect pests, the farmer will greatly simplify their care and protect his crop.

Advice from experts regarding the use of BI-58 for plants

Due to lack of knowledge and experience, beginners often have problems when using pesticides. Therefore, first you need to carefully familiarize yourself with the product used and understand the principle of its operation. It is also recommended to rely on the experience of specialists.

Experienced gardeners give the following advice regarding the use of insecticide:

Treatment with BI-58 immediately after frost is not recommended. In this case, the efficiency will be reduced significantly. For spraying, the optimal temperature range is from +12 to +35 degrees.
It is advisable to carry out all pest control activities during the active growing season. During this period, the greatest damage to the plant by parasitic insects is observed.
Typically, the BI-58 insecticide works the first time. But sometimes repeated spraying is required to completely get rid of insects. It depends on the type of crop.
The prepared solution must be used immediately. It is not worth storing it. The mixture should be diluted directly into the sprayer container. At the same time, it is worth constantly stirring it during cooking, as well as periodically during the processing itself.
BI-58 will help get rid of pests much worse if the water for the solution contains admixtures of clay or silt. Therefore, it is advisable to choose a clean, filtered liquid. It is also worth noting that when using hard water, the concentration of the solution changes.
During the flowering period, pesticide treatment is prohibited.
Ornamental plants must be handled with extreme care. Because there is a risk of burns.
It is important to know how to dilute BI-58 New or regular BI-58 correctly. If the dosage is calculated incorrectly, there is a high risk that the plant will suffer. This manifests itself in wilting and falling leaves.

Mechanism of action

As mentioned above, the drug acts in two directions: systemic and contact, due to which, strictly speaking, it provides maximum protection of plants from insects and pests.

Systemic action. First, the product is absorbed by the green parts of the plants, after which it is evenly distributed throughout the entire plant in the acropetal direction, that is, from the bottom up. Insects die as a result of absorption of juices. "Bi-58", instructions for use of which are included in the package, protects re-growing parts of plants from harmful insects. Due to the fact that the product has a fairly wide spectrum of action and is well tolerated by crops, it can be used on wheat, barley, oats, millet, legumes, apples, pears, plums, grapes, citrus fruits, beets, cabbage, potatoes, alfalfa, flax, currants , raspberries and many other plants.
Contact action. Insects present on the plant at the time of treatment die directly from the very effects of the insecticide, which acts through the integument of the pest.

What is the pesticide BI-58?

Pesticides are drugs that protect plants from the negative effects of the environment. They include two groups of substances: herbicides, whose action is aimed at killing weeds, and insecticides, which kill harmful insects. BI-58 belongs to the latter category. On store shelves you can find the drug BI-58 New and regular BI-58. Both of these products are insecticidal. And they are very popular. Also see the article: Why is Fitosporin-M needed for plants?

Characteristics and description of BI-58

BI-58 is a modern chemical product that effectively destroys parasites without causing harm to the treated crop. It is a systemic and contact insecticide. Its action is directed against sucking and gnawing parasites.

Dimethoate is the active ingredient of BI-58, which is an ester of phosphoric acid. Dimethoate is contained in a dosage of 400 grams per liter. The product is produced in glass ampoules with a volume of 10 milliliters and in plastic containers, which come in 1.5 and 10 liters. This is a concentrated emulsion. The unique composition of BI-58 allows you to protect vegetable and garden crops for a period of about 3 weeks.

The action of BI-58 occurs as follows. Upon contact with an insect, the substance quickly penetrates its integument and begins to poison the body. This is the essence of contact action. The systemic principle is based on the fact that the product is absorbed by the green parts of garden and garden plants and is distributed evenly inside. When an insect eats a crop, it also eats poison.

Features of the drug BI-58 New

Beginners in the field of plant growing often ask what is the difference between the new BI-58 and the old version, which drug is better to choose to get rid of annoying insects for a long time.

The active ingredient of New BI-58 is also dimethoad. Its concentration is 400 grams per liter. It is considered interesting that BI-58 New acts in several directions at once: systemic, contact and long-term. This allows you to significantly expand the protective effect. It also gives summer residents the opportunity to reap a rich harvest.

The insecticide BI-58 New is effective against potato moths, various caterpillars, mole crickets, ticks and other insect pests. It protects many plant species and has a number of positive qualities. This is what the manufacturer says. However, this drug is less popular among gardeners and gardeners. Many argue that in practice the New BI-58 is less effective than the regular BI-58.
