Purpose

The preparations of the BI-58, KE series are developed and produced by the BASF concern, a world leader in the chemical industry. Used mainly in agriculture.

Has a wide spectrum of action to protect fruits, vegetables and ornamental crops from most insect pests:

• leaf rollers;
• gall midges;
• aphids;
• mites (spider mites, kidney mites);
• bedbugs;
• leafhoppers;
• scale insects and false scale insects;
• codling moth and leaf-eating caterpillars;
• stem flies;
• thrips and many others etc.

Compatibility with other drugs

The BI-58 product can be mixed with insecticides and fungicides that do not have an alkaline reaction. Antifungal Strobi and pyrethroid Fastak show good results when used together. Mineral fertilizers are added to the working solution for spraying plants. Foliar fertilizing makes crops resistant to pests.

Upon contact with alkaline drugs, bonds that are toxic to humans are formed and cause poisoning. It is prohibited to use water with clay additives for preparing tank mixtures. Compounds for sprayers with growth stimulants and retardant herbicides are contraindicated.

Composition and dosage form

Active ingredient: dimethoate , dosage 400 g/l, chemical class: organophosphorus compounds (OP). Preparative form – emulsion concentrate (EC).

Examples of manufactured drugs “BI-58 NEW, CE”

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.

Instructions for use of the drug

Parasites quickly adapt to poisons, so strong pesticides are needed to control pests. The product "BI-58" is a reliable insectoacaricide that affects sucking and gnawing insects. To prevent the drug from causing harm, you must use the chemical according to the instructions.

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.

Composition and mechanism of action

Dimethoate is the active ingredient in the drug “BI-58”. Phosphoric acid ester after treatment is evenly distributed in tissues and in the intercellular juice of cultures. Plants accumulate toxins and become poisonous to all types of parasites. The protective effect remains in growing shoots and foliage. High performance is not affected by precipitation.

The insectoacaricide enters the digestive organs of sucking and gnawing pests. The substance paralyzes the nervous and respiratory systems of insects, which leads to mass death of the population after a day. Due to its composition, BI-58 is very dangerous not only for parasites, but also for pollinators and fish.

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.

Precautionary measures

"BI-58" is a poisonous drug that must be used according to instructions. To prepare the working solution, do not use food containers. To minimize contact with the active ingredients, use protective clothing, a mask and a respirator. Immediately after the procedures, clothes are washed, dishes are washed and a shower is taken.

Features of using the drug BI-58 on a 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.

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.

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.

Existing analogues of the drug

BI-58 is a popular insecticide. However, it is not always available. In this case, you can purchase an analogue of BI-58 or wait until the product goes on sale. There are many substitutes for this pesticide, including Rogor and Phosfamide, Accent, Dimetrin and others. Their main active ingredient is dimethoad. However, they are somewhat more expensive than BI-58.

What are the benefits of the pesticide?

The drug BI-58 for plants appeared on the market a long time ago, and thanks to its versatility, it quickly gained popularity and established itself as a reliable and safe insecticide for humans. It compares favorably with a number of other drugs, the action of which is also directed against parasites.

Insectoacaricide BI-58 has the following advantages:

1. Effective against a wide range of pests. So, it quickly copes with spider mites, aphids, thrips, leafhoppers and bedbugs.
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.
6. Creates long-lasting and reliable protection against several types of ticks and other insects.
7. Profitable price. The drug BI-58 costs much less than similar insecticides.
8. Possibility of processing throughout the entire growing season. However, one rule must be followed: stop spraying 3-4 weeks before harvest.
9. Consumption rates can be selected and varied.

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.

How to use BI-58 correctly?

The use of the insecticide BI-58 and BI-58 New involves the correct preparation of the solution.

To do this, you need to know what dosage is required for what crop. Therefore, before treating plants, you should carefully study the instructions that come with this drug.

Use of the drug BI-58

In order for the use of BI-58 to be as effective as possible, it is important to prepare the solution correctly. In principle, there is nothing complicated about this. You will need a bucket of water and the drug itself.

Before opening the ampoule, shake it well. For 5 liters of liquid you need one ampoule of BI-58, which contains 5 milliliters of the substance.

If the foci of infection are small, you can choose a proportion of 3 milliliters per 10 liters of water.

In order not to harm green spaces, it is important to know the correct consumption of BI-58, the exact dosage for each crop, and be able to dilute the product. You need to be extremely careful with insecticides.

For each type of plant, the consumption rate of BI-58 will be different. For example, for grains, 1-1.5 kilograms of concentrate per hectare are used.

As for legumes, root vegetables and cruciferous vegetables, the norms are slightly lower - from 0.6 to 1.2 kilograms. Fruit crops are treated at the rate of 1.6-2.5 kilograms of product per hectare.

If necessary, the amount of liquid should be increased proportionally.

Application of BI-58 New

Typically, 2 ampoules of the product are diluted in 10 liters of clean water. Wheat is treated with 1.5 liters per hectare. Spray during the growing season. The pesticide helps get rid of grass flies, harmful bugs, thrips, lechs and turtle aphids.

But the BI-58 norm for millet is 0.7-1.0 liters per hectare. Effective treatment against aphids and mosquitoes. For barley and rye you will need about 1 liter of solution. Pulses are sprayed at the rate of 0.5-1.0 liters per hectare. The pesticide fights against pea moths, aphids and moths.

Apple and pear trees are also often attacked by parasites. They are especially plagued by mites, moths, caterpillars, moths, scale insects, and weevils. For protection, you should use 0.8-2.0 liters of solution per hectare of area. Treatments are carried out before and after the flowering phase.

For plums, the norm is 1.2-2.0 liters. The insecticide kills mites, dust bugs and aphids. Vegetable crops are often affected by mites, aphids, bugs and thrips.

To get rid of these parasites, it is recommended to spray the solution during the growing season at a rate of 0.5-1.0 liters per hectare.

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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. During the flowering period, pesticide treatment is prohibited.
7. Ornamental plants must be handled with extreme care. Because there is a risk of burns.
8. 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.

Is BI-58 combined with other drugs?

The pesticide BI-58 has earned respect among farmers because it combines well with other drugs.

For example, with the fungicide Strobi and the pyrethroid Fastak. BI-58 has good compatibility with Abiga-Pik and other drugs. By combining the product with fertilizers for foliar feeding, it is possible to solve two problems at once.

The main thing is not to use the insecticide together with alkaline agrochemicals.

If the weather is damp, it is better to avoid using the drug in multicomponent tank mixtures with retardant growth and development stimulants and herbicides.

Thus, the insecticide BI-58 has long been known to plant growers. This drug is very popular due to its high efficiency and reasonable cost. It is sold in ampoules of 5 milliliters. It is very easy to dilute: the ampoule is dissolved in 5 liters of water. The pesticide is effective against many parasites.

Suitable for spraying almost all vegetable and garden crops. But we must remember that this is poison. And in order not to harm the plant, you should use it wisely, know when to apply the treatment and what dosage to use. The harvested crop can be used for food a month after contact with BI-58.
