How to breed "Bi-58": instructions for use of the drug

With an increase in the number of pathogenic bacteria, weeds, insects, their adaptation to adverse conditions, the demand for toxic chemicals increases proportionally. The effectiveness of the protection of agricultural, flower and ornamental crops from diseases and pests largely depends on the method of administration of drugs and the active substance. More than 10 thousand names of the agrochemical industry are allowed in Ukraine. Among the frequently requested insecticides "Bi-58". Based on the instructions for use, manufacturer's recommendations and consumer reviews, we will analyze the properties and effectiveness of the drug.

"Bi-58": description and forms of release of insecticide

In agrochemistry, the drug "Bi-58" gained a reputation as a universal remedy for use in agriculture and floriculture from gnawing and sucking herbivorous parasites. The chemical is classified as insecticaroacaricide organophosphate group with a wide spectrum of action. The drug was developed by the German manufacturer "BASF SE" in factories in the Danish Lemvig and Ludwigsfahene in Germany. In Ukraine registered for disinfection of wheat, barley, rye, oats, millet, leguminous and vegetable crops, beets, hops, apple trees, pears, plums, vineyards, potatoes, tobacco, alfalfa, raspberries, currants and mulberries.

With the rapid development of agrochemistry, the latest developments soon pushed the outdated Bi-58 out of the market. But the manufacturers responded in time by improving the pesticide formula and announced the appearance of the insecticide Bi-58 New.

The tool is a 40% emulsion concentrate that has a systemic effect on pests when in contact with and released into the intestine. Acts instantly, without poisoning the plant. Protective function is maintained for 21 days, regardless of weather conditions. The use of the drug "Bi-58 New" is allowed throughout the growing season, with the exception of 30-40 days before harvesting.

The melting of the emulsion begins at 51 ° C. Insecticide is moderately soluble in water, better in organic compounds. Does not take out sunshine, under their influence begins to decompose.

Toxic characteristics of the drug determine it to the 3rd class, although among professional gardeners there is a perception of the strongest threats of a pesticide. For the purpose of safety, "Bi-58", according to the instructions for use, is not advised to use in higher dosages and in closed rooms. When spraying on open ground, manual and mechanical work on all crops is allowed only after 10 days.

Available in ampoules of 5 ml, bottles and cans, with a capacity of 1 l, 5 l, 10 l, 20 l. The liquid may be dark blue or milky. Farmers and gardeners in a review say about the abilities of the "Bi-58" and "Bi-58 New" to destroy nymphs, tsikadok, earwigs, moths, thrips, bedbugs, larvae and mature ticks, and also mention the poor permeability to the shell of eggs, which causes the need for re-processing. We are talking about increasing yields on sprayed plants, because the tool does not leave the slightest chance to survive even the most inveterate and resistant insects.

Active ingredient and mechanism of action "Bi-58"

The insecticide is based on dimethoate, which is the most complex phosphoric ester. During disinfection, the active substance is systematically and systematically absorbed into the plant fibers, proceeding upwards. "Bi-58" soaked even appeared young shoots, which guarantees disposal of any kind of pests. Insects living in roots, stems and leaves receive a lethal dose of toxins on contact, and as a result they die instantly. Strengthens the effect of intestinal effect.By devouring the green mass and juice of the culture, the parasites poison themselves. The effectiveness of the insecticide is possible even in adverse weather. Fumigation qualities are very weak, practically absent due to the volatile composition of the emulsion.

Dimethoat affects the enzyme responsible for the transmission of nerve impulses. Due to its binding, insect activity is lost, tremor, paralysis and death appear.

How to breed "Bi-58": instructions for use of the drug

"Bi-58 New" is a potent drug, so before you breed it, carefully read the instructions and recommendations for use. In the process of preparing the working solution, make sure that the water is soft, otherwise the concentration of the substance is modified. Also, inherent silt and clay impurities have a destructive effect. It is better to plan disinfection on a dry sunny day at an optimum temperature from 12 to 35 degrees Celsius.

Spring spraying of the garden is carried out in a period of intensive development, when the highest degree of accumulation of harmful insects. Insecticide developers warn of possible reprocessing of certain crops.

If the "Bi-58" is packaged in ampoules, the working solution is prepared at the rate of 5 ml per 5 l of water. For disinfection of small foci of infection, a proportion of 3 ml per 10 l can be calculated. Be careful: if you incorrectly calculate the dosage, the plant may suffer - lose the foliage and generally wither. Shake vials or other containers with insecticide before use. Dissolve the contents directly in the sprayer tank while constantly stirring the solution for better dissolution.

Manufacturers of "Bi-58" in the instructions provided for how to breed a tool for each type of plant. For example:

• for spraying 1 hectare of wheat and hops will need about 1.5 liters of the working solution;
• 1.0-1.2 liters of liquid will be dispersed per hectare of rye, oats and barley, as well as vineyard, plums and currants;
• about 0.5 l of pesticide will be needed for a similar area of ​​pulses, alfalfa and beets;
• for processing "Bi-58" 1 ha of vegetable crops consumption rate 0.5-1 l;
• potatoes are disinfected at the rate of 2.0-2.5 l / ha;
• apples, pears - 0.8 l / ha;
• mulberry - 2.0-3.0 l / ha;
• raspberry - 0.6-1.0 l / ha.

Be especially careful when spraying insecticide on ornamental plants, as the drug can leave behind after severe burns on the leaves.

Compatibility "Bi-58" with other means

The toxic chemical has earned the respect of farmers and good compatibility with other drugs. Effective combination of fertilizers for foliar feeding with "Bi-58", also fungicides with acidic and neutral reaction ("Strobe"), pyrethroids ("Fastak"). The exception is alkaline agrochemistry.

The maximum biological effect of an insecticide is achieved at 20-25 degrees of heat. In wet weather and heat it is worth avoiding the use of the drug in multicomponent tank mixtures with herbicides and growth retardant-type stimulants.

Is it possible to poison "Bi-58": precautions

"Bi-58" is a very toxic insecticide for bees, 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). For a person does not pose a threat while observing precautions. Otherwise, it can 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 listed symptoms after working with agrochemical, immediately contact your doctor for help. Do not waste time, because the drug inhibits the function of cholinesterase, an enzyme that signals the nerve impulses. Subsequently, cardiovascular imbalance and loss of consciousness is possible.

In such situations, it is necessary before the arrival of the doctor 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 a sharp unpleasant odor of the substance, therefore when using the "Bi-58" it is important to have a competent dosage and protective equipment. All work, including preparatory work, should be carried out in overalls, goggles, rubber gloves and boots, as well as in a headdress.It is strictly forbidden to eat, smoke, drink alcohol at the same time. It is also recommended to limit contact between hands and face as much as possible.

After preparing the working solution and treating the plants, the respirator is removed, the gloves are thrown away, they change their clothes, they wash their hands with soap and water, they wash their faces and rinse their mouth thoroughly.

It is unacceptable to contaminate the sources, reservoirs, wells with the remnants of the solution. Also near them it is not necessary to carry out disinfection and pour out the water after cleaning contaminated in the process of working containers and equipment. Knapsack sprayer washed daily, re-treating the culture with plain water. Emptyed containers after agrochemistry need to be burned, not inhaling the smoke and released particles.

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

Be attentive to your well-being. If the poison gets on the skin, remove it without rubbing it with cotton wool, then rinse with running water or a weak solution of soda.In cases of contact with the eyes, rinse with plenty of water for 15 minutes. For swallowing and irritation of mucous membranes, consult a doctor. It is important to keep the label from the packaging of the insecticide.

Ensure spraying occurs away from children and pets. Poisoning poisoning in cats is manifested by tremor and drooling, in rabbits neck muscles are weakened.

"Bi-58": storage conditions and shelf life

The instructions for the preparation "Bi-58 New" provide for a shelf life of 24 months from the date of manufacture at optimum temperatures from -10 to +25 ° C. To store the pesticide should be in a dark, inaccessible to children and animals place, away from medicines and food. The saving of residual working solution is unacceptable. Liquid use without fail immediately after preparation. Remains are disposed of.
