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. In Ukraine, more than 10 thousand names of the agrochemical industry are allowed. 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.
Important! In order not to fall for the charlatans, do not buy toxic chemicals in the markets, prefer specialty shops that value their reputation. Look at the package. The original copies must contain information on the manufacturer, the place of packaging, the date of manufacture and the period of suitability. Pay attention to the hologram badges and literacy instructions for use.
"Bi-58": description and forms of release of insecticide
In agrochemistry, the drug "Bi-58" has 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With the rapid development of agrochemistry, the latest developments soon pushed the outdated Bi-58 out of the market.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 formulas and announced the appearance of the insecticide "Bi-58 New".
The tool is a 40% emulsion concentrate, has a systemic effect on pests upon contact and into the intestine. Acts instantly, without poisoning the plant. The protective function is maintained for 21 days, regardless of weather conditions. The use of the drug "Bi-58 New" is allowed throughout the vegetation period, with the exception of 30-40 days before harvesting.
The melting of the emulsion begins at 51 ° C. The insecticide is moderately soluble in the aquatic environment, 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 cultures is allowed only after 10 days.
Did you know? The first chemical insecticide used by humans was sulfur as a remedy for lice.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 preparations "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" soak 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, as a result of which they instantly die. 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.
Important! Treating trees with Bi-58 cannot be performed at low temperatures. During and immediately after frosts, there is a high risk of losing the basic properties of the insecticide.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, you can calculate the proportion in the ratio of 3 ml per 10 liters. Be careful: if you incorrectly calculate the dosage, the plant may suffer - lose the foliage and wither in general. Shake vials or other insecticide containers thoroughly before use. Dissolve the contents directly in the sprayer tank while constantly stirring the solution for better dissolution.
The 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 working solution;- 1.0-1.2 l of liquid will spread on 1 ha 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 of 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.
for spraying 1 hectare of wheat and hops will need about 1.5 liters of working solution;Did you know? "Bi-58" disappears from the surface of fruit and vegetable crops in three days, and the ground is held in the ground for a year.
Compatibility "B-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 under the precautionary measures. 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 an agrochemical, immediately contact your doctor for help. Do not waste time, because under the influence of the drug inhibits the function of cholinesterase - an enzyme that gives a signal about 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 cause vomiting.
A significant "minus" of the insecticide is the sharp unpleasant smell 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 the contact of hands and face as much as possible.
Important! Dimethoate (active ingredient "Bi-58") is not strongly recommended in the berries and orchards, where the aisles are used for the cultivation of vegetables for greens.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 mouths 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 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, without inhaling 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 insecticide packaging label.
Ensure spraying occurs away from children and pets. Poisoning poisoning in cats is manifested by tremor and drooling, in rabbits neck muscles are weakened.
