Dusting

Dusting is one way of combating harmful arthropods (carriers of pathogens), as well as rodents and their parasites, which consists in drawing on the earth, plants and other toxic powder.
To kill the larvae of mosquitoes in the area of their emergence allow dusting 12% of dust HCH rate of 1 -10 kg per 1 ha (depending on the kind of mosquitoes, local conditions). The dusting of reservoirs minimum dose of HCH 0,88 kg per 1 hectare
For the destruction of adult mosquitoes, midges Pets dusting areas the same ustami based 7-10 kg, maximum 15 kg per 1 hectare
Epidemic indications in the areas affected by tick-borne encephalitis, dusting spend 10% of dust DDT at the rate of 30 kg per 1 ha under ground handling and 30-50 kg per 1 ha with air-treatment; opisyvayut territory in areas populated by Ixodes ticks.
Processing areas are conducted in early spring snow. With such a dusting of large spaces a special effect lasts up to three years.
Special processing of the territories children's health institutions in the centers of tick-borne encephalitis is conducted every year regardless of the number of ticks, use of other insecticides such as karbofos, triclofos.
Rodents destroyed by dusting Nord. In urban conditions apply warfarin, Krysin.
Ground dusting ustami insecticides carried out with the help knapsack equipment; dusting Nord - hand sprayers. For dusting large areas using combined installation on a motorcycle (CDP), vehicles "Gazelle"; for aviobilesu used specially equipped planes an-2, MI-1 and other
All works on dusting territories powder poisonous drugs is carried out with the permission and under the supervision of the sanitary and epidemiological service.
Dusting areas of pesticides prohibited for processing pastures, hay fields, water bodies, having economic significance, areas with fruit-berry, vegetable crops, the locations of apiaries and other
All the work with insecticide is conducted strictly according to the rules of safety and only in the protective clothing (overalls, rubber gloves, boots, goggles). For respiratory protection from powdery drugs are anti-dust respirators type U-2K or f-K. While dusting it is forbidden to smoke, eat and drink. After work it is necessary to take a shower.

Dusting is one of the ways of drawing of a powder of insecticides and fungicides to different objects. Dusting is widely used in the fight against arthropods, including vectors of infectious diseases, parasitic life, parasites of animals, harmful rodents, pests, and diseases C. agricultural animals and cultivated plants (including forest plantations). In order to increase the stickiness to powdered drugs sometimes added mineral oil and other
For Acting ponds, fields, forests, agricultural crops. cultures, different surfaces, clothing, animals, use of special devices and machines, which are divided into manual, knapsack hand, horse-riding, horse-motor, tractor (trailer posted on a special truck, and hinged mounted on the tractor, automobile and aviation.
In medical practice are used for manual spray (PR-2) and manual ventilation apparatus (WFD-1), and of mechanized vehicles - engine spray on a motorcycle (MPI-2), combined disinfection unit (sprayer-opylitelei) on motorcycle (Fig. 1), Serna and others (see Disinfection devices). In agriculture used tractor mounted opylitelei-sprayer (Fig. 2) and others To combat mosquitoes and ticks dusty sprayed from planes (2) and helicopters (Mi-4S). Aviamilano used in cases when it is economically more profitable than other methods. This is the main way of disinfection processing of large water bodies and large areas.

In epidemiological practice dusting used to fight with mosquitoes, gnats, mosquitoes, biting midges and their larvae, ticks, lice, fleas, flies and other insects. Ground O. used for the treatment of small water bodies and narrow coastal strip, infested by mosquitoes. Large areas of forests opisyvayut to destroy ticks - keepers and vectors of the virus of tick-borne encephalitis.
For Acting as dezinficiruyusch funds (see) use 10% Douste DDT, 6% Douste hexachlorocyclohexane is based in the fight against mosquitoes 20 kg per 1 ha, and under the control of ticks 30 kg per 1 hectare as DDT and hexachlorocyclohexane long preserved in the ground and are absorbed useful plants, study dusty other insecticides - with less stability in the external environment and insoluble in water (Savina, vofatox, trichlormethane-3, karbofos and others). Dusty with chlorophos ineffective due to its solubility in water. For Acting also use granular insecticides that better reach the earth surface.
Dusting during flowering of plants can be damaged flowers and poisoning of bees. So apiary removed from opisyvaemyh plots at least 10 km. Cm. also Disinsection.
