HOS: instructions for the use of organochlorine compounds, preparations and analogues

Pesticides used in agriculture belong to different classes of chemicals. Consider the physico-chemical properties of COS - organochlorine compounds, the effect on pests, what products contain, how to apply according to the instructions, how to work according to the precautions. Compatibility, term and conditions of saving, analogues of substances.

Physical and chemical properties

COSs have excellent chemical resistance to negative environmental factors (temperature, ultraviolet, humidity). Chlorine compounds were the leaders in terms of production and extensive use in agriculture until the 1980s.The main drugs were DDT and HCCH, but after a while, due to long-term use, they became sources of environmental pollution with residual compounds.

Organochlorine compounds dissolve poorly in water, soluble in organic substances, including fats. Some substances are volatile.

Action on pests

Getting into insects and organisms, organochlorine is converted into other substances according to 3 schemes:

• slightly toxic products are formed;
• resulting in epoxides and other toxic metabolites;
• hydrolyses to water-soluble compounds that are easily excreted from the body.

Properties and what selectivity the substances will show depend on how the XOSs are converted.

Organochlorine pesticides are predominantly of contact action, the breadth of the spectrum of action and the longitude of the protective effect are noted.The active substances of COSs act on the central nervous system of pests, interfere with the normal passage of nerve signals. Insects die from overexcitation and subsequent paralysis, the death process is not fast and can last up to a week.

With prolonged or systematic use of COS, insects become resistant to the means, generations resistant to them appear.

What preparations does it contain?

Hexachloran is a strong contact, systemic, intestinal toxin and fumigant. Preparations with it are used to control pests of vegetables, industrial and fruit crops.

DDT was previously used, including in combination with other active compounds, in agriculture - to effectively control insect pests, including those living in stocks, and to destroy vectors of pathogens. Available in the form of 5.5% and 10% dust, 30% and 50% powder, 20% concentrated oil emulsion, 50% paste emulsion and smoke bombs.

Instructions for use

Organic chlorine used to be the leader among pesticides, preparations were used as insecticides, acaricides and fungicides with powerful and guaranteed action. Preparations were used on cereals and legumes, vegetables and industrial crops, on fruit and vineyards, in forest plantations. COSs were also used for veterinary and medical treatment of animals and premises from zooparasites. Due to toxicity, DDT has been banned for use as pesticides.

Precautions

CHOS-drugs are highly toxic to humans, animals, insects, accumulate in groundwater and fruits. People in special clothes should work with the funds, you need to wear a tight respirator with a filter or a gas mask.

During work, you can not smoke, use fire, eat (food is allowed during rest, after washing hands, nose and mouth).

After working with HOS, you need to take off your clothes and wash your hands and face, wash off the solution if it accidentally gets on the skin, eyes or mouth. If symptoms of poisoning are found, flushing should be done, if this does not help, and the condition will only worsen, you should consult a doctor.

Compatible with what?

COS preparations are recommended to be used alone, not mixed with pesticides. They are active on their own and have a pronounced effect, so they do not need to be enhanced by any drug. If it is necessary to apply the agent, then they need to be processed some time after the application of organochlorine.

Terms and conditions of storage

To keep HOS stable, they need to be stored properly. Preparations may decompose during long-term storage. This happens under the influence of ultraviolet radiation, heat. And also when in contact with metals, oxygen, moisture, acids and metal s alts.Therefore, it is important to store COS products under stable conditions, in specially designed warehouses for pesticides and fertilizers. Do not store food, medicines, animal feed, household products near these substances. It is important that animals and children cannot come into contact with pesticides that can be toxic to them.

Means analogues

Analogues of HCCH (hexachloran): Lindatox, Lindaram, Gamatox, Agrizert, VNS, Lindane. DDT analogues: "Methoxychlor", "DDD", "Pertan", "DFDT".

Organic chloride has long established itself as a complex useful for pest control and effective drugs for use in agriculture. It has an action of different directions, can destroy grass, insects and mites on many types of cultivated plants. It has a fast, powerful effect, a long-lasting effect is noted. COS products were used not only in fields and gardens, but also for the treatment of animals infected with parasites, for cleaning premises from insects.

Despite their effectiveness, CHOs are also highly toxic, unsafe for living organisms, can be found in plants, soil and especially in water. Because of this, in many countries they are limited in use or completely prohibited. When working with HOSs, you must adhere to strict safety rules, work only in protective clothing and special equipment.
