The fight against harmful insects exhausts not only gardeners, but also the plants themselves. The new insecticide “BI-58” will help simplify the difficult work of the farmer, the instructions for use of which contain some features. It describes dosages for a wide variety of crops, and also lists groups of pests. In addition, it explains how to dilute the pesticide, what its shelf life is and how to spray the working solution on plants.
This product belongs to the category of organophosphorus compounds, since the active substance in it is dimethoate. Once on the surface or in the intestines of insects, it paralyzes living tissues. In the green mass of the crop, chemical bonds are maintained for 3 weeks, thereby protecting it from pests.
Mechanism of action of the drug
“Bi-58” is used on many crops to destroy aphids, caterpillars, flies, bedbugs, thrips, scale insects, moths, leaf rollers, codling moths, flower beetles, cutworms, gall midges, leafhoppers and some types of mites.
This insecticide has a powerful and complex effect. The solution is absorbed by leaves and green parts of plants and then spreads evenly. Pests die as a result of feeding on poisoned plant sap. The insecticide also acts by contact; insects die when the solution comes into contact with them after spraying.
Consumption rate
The dosage of “BI-58” depends on the type of plant and the size of the area. To treat potatoes against parasites, you need to use 2 liters of working solution per hectare. To spray stone fruit trees you will need 80 ml per 100 squares. 1.5 liters of toxic liquid in standard concentration is used to protect:
- hops;
- barley;
- rye;
- oats;
- wheat.
“BI-58” against mites, leaf rollers on grapes and currant bushes, raspberries, and gooseberries is used in a volume of 1 liter. To protect legumes, beets and alfalfa from parasites, you need to use 500 ml of the chemical. The consumption rate for mulberries is 3 l. The amount of solution is indicated per 1 ha. Carefully spray decorative and indoor species with poison, using the lowest concentration.
How to breed and use Bi-58
The instructions for use indicate that the drug can be used against a number of pests belonging to different orders. The product remains effective over a wide range of temperatures. The protective effect of the insecticide lasts 2-3 weeks. When used in the recommended dosage, it does not exhibit toxic effects on plants.

On all crops, except grapes, apples and pears, “Bi-58” sprays pests during the growing season, spending 200-400 liters per hectare. 2 treatments are carried out, the waiting period is 1 month for grains, grapes and beets, for apples and pears – 40 days. Fruit trees are sprayed before and after flowering, consumption - 1000-1500 l, against flower beetle - 800-1000 l. Grapes are treated against mites, leaf rollers and scale insects with a solution of 600-1000 liters per hectare.
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:
Special instructions and precautions
"Bi-58" refers to drugs with hazard class 3 for humans, that is, low toxic. The product is highly toxic for bees and has an insect hazard class of 1. Due to the high toxicity of the drug, it cannot be used on flowering trees and in gardens near which there are apiaries. Also, this powerful drug is toxic to fish, so it cannot be used in areas with plants located near water bodies and fishing enterprises.
When working with the Bi-58 preparation, you must wear protective clothing, you need to wear long sleeves, gloves on your hands, a respirator and goggles on your face to protect your nose and eyes from splashes of the solution, which can cause irritation and poisoning. .
After finishing work on spraying “Bi-58” you need to wash your face and hands with warm water and soap. If the solution suddenly gets on your skin or eyes, you should immediately rinse them with plenty of water. If the insecticide gets inside, you need to rinse your stomach: drink activated carbon tablets, wash them down with 1 liter of water and after 15 minutes induce vomiting. If after self-treatment the symptoms of poisoning do not disappear, then you need to consult a doctor.
Precautions when working with the drug
- When working with such poisons, you need to be careful and use protective equipment: a respirator, goggles, rubber gloves.
- After treatment, wash and change clothes.
- The remaining solution must be disposed of.
- The drug is poisonous to bees, animals and fish, so you should not pour the remaining solution into water, or spray it during the flowering period of plants.
- The emulsion should be stored out of the reach of children and animals. Keep them away from the drug solution.
- Parts of treated plants can be consumed only a month after spraying.
- If you have symptoms of poisoning (nausea, dizziness, drowsiness), you should immediately call a medical team.
Interaction with other tools
"Bi-58" mixes well with fungicides, especially pyrethroids, in tank mixtures. Can be mixed with fertilizers for foliar feeding. The exception is products with an alkaline reaction. The combined use of Bi-58 and fungicides reduces the dosage and consumption of both drugs, without reducing the effectiveness. This makes their use economically profitable. It is recommended to mix the insecticide with the drug "Fastak" if treatment is necessary with a large number of pests.
