Abstract

The invention discloses a pesticide airplane spray aid. The pesticide airplane spray aid comprises, by weight, 10-15% of polyoxyethylene glyceryl ether, 15-20% of fatty alcohol-polyoxyethylene ether,20-25% of chlorohydroxypropyl alkylamine ether quaternary ammonium salt, 10-15% of sodium dioctyl sulfosuccinate, 10-15% of block polyether, 5-10% of a polynaphthalene sulfonate dispersing and wettingagent, 5-10% of a polymer anti-drifting agent, and the balance of water. The invention also discloses a preparation method of the pesticide airplane spray aid. The pesticide airplane spray aid has anexcellent permeation effect, is only used for insecticides and bactericides, and can better promote absorption of a target to a liquid pesticide and improve the pesticide effect.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, in particular to a fly control adjuvant and a preparation method thereof. Background technique [0002] At present, my country's conventional spraying can only be sprayed evenly after diluting the chemical with 30-50 kg of water per mu. Agricultural low-altitude spraying uses less water, no more than one kilogram per mu, and belongs to low-volume or ultra-low-capacity spraying. The use of drones to replace traditional manual spraying is a new type of plant protection method that has gradually become popular in China in the past two years. Its biggest effect is that it greatly reduces labor costs and has high work efficiency. It is especially suitable for large-scale plain areas. For complex Under the precise positioning of Beidou navigation, precise spraying can also be achieved on hilly terrain. [0003] For UAV flight defense, special flight defense additives play a very critical ...
