In the process of absorption of the substance by the leaves of the plant, the diquat molecule is restored, as a result of which a stable radical is formed, which can be re-oxidized by molecular oxygen. As a result of electron attachment, oxygen turns into a highly reactive superoxide anion (О ^2- ) and hydrogen peroxide (Н ₂ 0 ₂ ), which can directly oxidize unsaturated fatty acids and cause the formation of malondialdehyde due to inactivation of the electron transport system, which causes rapid destruction of the tonoplast, destruction of cellular contents (mitochondrial rupture, destruction of the thylakoid membranes in chloroplasts) and the death of the plant as a whole.

Scorpio is a contact desiccant designed for pre-harvest desiccation of sunflower, as well as testes of vegetable, fodder and industrial crops. Accelerates the drying process, especially with uneven ripening of plants, facilitates cleaning. It is also used as a herbicide for pre-emergence protection against annual dicotyledonous and cereal weeds in a number of crops.

Scorpio is compatible with urea, but is not compatible with drugs that have an alkaline reaction, anionic surfactants, alkali metal salts and auxin-like herbicides.

The optimum temperature for use of the drug 10 + … + 20  ^of S. Use of the drug at low temperatures (less than 10  ^of C) slows down the visual manifestation of symptoms on plants of the drug, but does not affect its effectiveness.

Sunny and hot weather accelerate the manifestation of visual signs of the action of the drug, but somewhat reduces the effectiveness of its action. Rain 15-30 minutes after application of the drug does not reduce the effectiveness of the action on plants.

The presence of dust, dew on the surface of plants, as well as adverse conditions (arid conditions, dry winds) reduce the effectiveness of the drug on plants, so it is not recommended to use the drug under these conditions.

When working with the drug Scorpio, it is important to correctly determine the timing of desiccation. Begin processing crops or plantings when physiological ripeness of seeds occurs at a moisture content of 30–50%, depending on the crop. Processing earlier can result in lower yields. The intensity of desiccation depends on the consumption rate of the Scorpion preparation, plant density, weediness of crops, weather conditions at the time of treatment and after it. Increase the consumption rate of the drug with an increase in leafiness of the crop, high weediness of crops and plantings, with high humidity, as well as when harvesting is necessary in a short time. in sunny, dry weather, the rate of desiccation increases. The rate of flow of the working solution should be sufficient to completely wet the entire sheet surface.

The drug is used by tractor ground spraying and aircraft processing. For ground spraying of weeds, commercially available boom sprayers are used: OP-2000-2-01, OP-2000, OPSh-15, etc. during aircraft processing – An-2 aircraft with spraying equipment 2102.0272.000, Ш76-7000, OS-1M and Mi-2 helicopter with equipment 52.81.250.00.00 and 4202.0691.000. The flow rate of the working fluid is 200-300 l / ha for tractor spraying; 50-100 l / ha for aircraft processing.

First aid for poisoning:

If there are signs of malaise (nausea, weakness, dizziness, headache), the victim must be removed from the danger zone to fresh air, carefully remove clothing and a respirator, avoiding the possibility of the drug getting on the skin or respiratory organs.

If the product gets on the skin, immediately remove contaminated clothing, remove the preparation with a paper towel, a piece of cloth or cotton wool, avoiding rough rubbing of the skin, and then thoroughly wash the skin with soap and water.

In case of contact with eyes, rinse immediately with plenty of clean, running water.

If the drug enters the stomach, immediately give a few glasses of warm water with activated charcoal to drink (based on 1 g of sorbent per 1 kg of body weight), then induce vomiting by irritation of the posterior pharyngeal wall. Repeat this several times to more completely remove the drug from the body.

In all cases of poisoning after first aid, the victim must consult a doctor.

There is no specific antidote. The treatment is symptomatic.

Methods for neutralizing spilled or spilled pesticide:

All neutralization measures are carried out using personal protective equipment in a room equipped with supply and exhaust ventilation or in the open air, on a specially equipped site.

When a significant amount of the drug is spilled onto the soil, it should be prevented from entering the sewers or water bodies. Pour the spilled preparation with sand, earth or sawdust until completely absorbed, then collect the adsorbent material in a container, seal the containers and send them for further disposal. The land from which contaminated soil has been removed is treated with a solution of bleach and dug up.

Contaminated soil and spilled preparation in containers are treated with a solution of bleach until the complete decomposition of 2,4-D acid (20-24 hours) and washed with water.

Methods for destroying or disposing of pesticide:

Destruction and neutralization of the drug, waste not subject to disposal, containers from under the drug are carried out in accordance with SN 3183-84 “The procedure for the accumulation, transportation, neutralization and burial of toxic industrial waste”, approved by the USSR Ministry of Health on 06/17/1985. and “Temporary instructions for the preparation for burial of banned and unsuitable for use in agriculture pesticides and containers from them”, VNIPIagrokhim, Ryazan, 1989.

Neutralization of pesticide wastes by treating them with 5% alkali solution or 7-10% sodium salt solution, followed by thermal neutralization.

The disposal of pesticide residues is carried out in specially designated areas. All work related to the disposal of pesticide residues should be carried out in agreement with the local sanitary and epidemiological control authorities and in full compliance with local laws.

Security measures during transportation, use and storage of the pesticide:

In order to prevent poisoning when working with the drug, it is necessary to observe the precautions specified in the “Hygienic requirements for the storage, use and transportation of pesticides and agrochemicals” SanPiN 1.2.1077-01 and in the “Safety Instructions for Storage, Transportation and Use of Pesticides in Rural economy ”(M, 2001).

During work, observe the rules of personal hygiene. At the workplace it is forbidden to eat, drink, smoke.

All work with the drug (opening containers, refueling sprayers, spraying and other work in the treated areas) should be carried out with the mandatory use of personal protective equipment: respirator, safety glasses, cotton overalls, hats, safety shoes. Persons engaged in the preparation of the working solution must have aprons and sleeves made of film fabric. Every week, overalls should be degassed in a soap-soda solution (2.5% soap and 0.5% soda ash), followed by washing in the same solution. Wash rubber gloves and boots with water.

Admission to work with the drug is made after instructing on precautions when working with pesticides, as well as after training in providing first aid measures for poisoning. Adolescents under the age of 18 years, pregnant and lactating women, as well as persons who have revealed a preliminary medical examination of diseases that are a contraindication to working with pesticides, are not allowed to work with the drug. All work is carried out under the guidance of plant protection specialists.

At the places of use of the drug should be a first aid kit.

The drug should be stored in an unbroken factory packaging, equipped with a container label indicating the name of the drug and the date of its manufacture. Storage at temperatures from minus 100C to plus 300C.

Storage of the drug together with food and fodder is not allowed. Storage of the drug is allowed only in warehouses specially designed for this purpose that meet sanitary requirements separately from other pesticides. The warehouse should protect the pesticide from direct sunlight, moisture, contamination and mechanical damage.

Joint transport and storage of the drug with feed and food products is not allowed. Transportation of people with the drug is not allowed.
