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.

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.

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.

Mechanism of action

Insectoacaricides of the “BI-58, KE” series have a systemic effect - they are absorbed by plant parts and then acropetally distributed throughout the entire plant. Dimethoate penetrates plants through the root system and above-ground organs, and spreads through plant tissues by ascending and descending currents.

The method of entry into the insect’s body is contact-intestinal.

a) Intestinal action : 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 is provided from harmful insects, including on newly growing parts of the plant.

b) Contact action : the drug has a pronounced contact effect on insect pests located on the surface of the plant at the time of treatment and actively acts through the integument of the insect.

Like other organophosphorus insecticides, dimethoate affects cholinesterase, an enzyme that transmits nerve impulses. Cholinesterase binds, as a result it loses its activity and cannot cause hydrolysis of acetylcholine. If cholinesterase is blocked by a pesticide, then free acetylcholine accumulates in the synaltic cleft, the normal passage of nerve impulses is disrupted, and tremor (convulsive muscle activity) occurs, which turns into paralysis.

Application area

The systemic drug was developed to combat insects in large and small agricultural farms. The chemical shows good results against both adult forms and larvae. “BI-58” is effective against the following pests:

• caterpillars;
• ticks;
• codling moth;
• nematodes;
• aphids;
• thrips;
• scale insects;
• leaf roller.

Insectoacaricide helps to cope with parasites in greenhouses, greenhouses and indoor plants. A high concentration of the working solution often leads to burns on flowers and decorative species. To avoid problems, you need to strictly follow the dosage of the poison.

Treatment is carried out by spraying during the growing season.

The timing, dosage, cost rates and frequency of treatments for various crops in agricultural production are summarized in the table. Before calculating the dosage for use on private farms, the dosage is approximately calculated from the following ratio: 1l/ha = 10ml/10l. water.

2. Compatible with fertilizers and fungicides. The exception is alkaline products.
3. Can be used at different temperatures.
4. Not phytotoxic.
5. The result after treatment occurs almost instantly.

True, the BI-58 product has some disadvantages. Among them it is worth highlighting the following:

• The presence of a pungent, strong odor.
• If the dosage is not observed, there is a risk of causing damage to the plant. Manufacturers classify BI-58 as hazard class 3. However, experienced gardeners claim that the product most likely belongs to class 2. It is highly undesirable to use the drug indoors in increased dosage. Therefore, when treating indoor crops, it is better to choose a more gentle product.
• The insecticide is dangerous for bees. It also has a negative effect on fish. Therefore, it is prohibited to use it near water bodies. But for warm-blooded animals the substance is slightly toxic. When the product gets on human skin, it slightly damages it. But the mucous membranes are extremely sensitive to dimethoad. So, when working, it would be a good idea to use additional protective equipment and use the BI-58 very carefully.
