Dedicated additive for hot fog machine and preparation method thereof

Abstract

The invention discloses a dedicated additive for a hot fog machine and a preparation method thereof. The dedicated additive for a hot fog machine comprises the following raw material components in percentage by mass: 5-20% of surfactant, 1-25% of hot fog density modifier, 1-10% of antifreeze agent, 0.1-6% of antifoaming agent and the balance of water. When the dedicated additive is prepared, all raw material components which can be dissolved into water are mixed to obtain an aqueous phase; then the insoluble hot fog density modifier is introduced into the aqueous phase; the hot fog density modifier and the aqueous phase are stirred; and residues are removed by filtering to obtain a finished product. According to the dedicated additive, the prevention and treatment safety and effect of thehot fog machine can be effectively improved, the type range of the hot fog machine on preventing and treating crop pests is expanded, the compatibility problem of pesticides, smoke agents and water can be solved, and the problem that the hot fog machine is applicable to middle-stalked crops and short-stalked crops, such as corn, wheat and the like is solved.

Description

technical field [0001] The invention relates to the field of high-efficiency dispersion of pesticides, in particular to a special additive for a hot fog machine and a preparation method thereof. Background technique [0002] The working principle of the hot fog machine currently on the market is: through the combustion of fuel to generate high-temperature and high-pressure airflow to vaporize the pesticide and the pesticide carrier, when the vaporized product sprays out of the nozzle and enters the atmosphere, it cools down sharply and liquefies or solidifies rapidly into a micron level Particles, and form aerosols with the air. When the plant layer diffuses and encounters plants, the drug-containing aerosols deposit and orderly attach to the surfaces of plant leaves, stems, etc., so as to achieve the purpose of preventing and controlling plant diseases and insect pests. [0003] There are many advantages to using a hot fog machine for spraying: first, high operating efficie...

AI Technical Summary

Problems solved by technology

[0004] However, the current use of hot fog machines also has serious defects. Without special treatment, the density of the hot fog sprayed by the hot fog machine is low, and it is easy to diffuse into the upper layer and enter the atmosphere, and it is also easy to drift with the wind, resulting in a decline in the control effect. And cause environmental pollution, it is usually only suitable for the control of tall plants such as forest diseases and insect pests, or only suitable for relatively closed spaces such as warehouses, greenhouses, etc. etc. prevention
