Problems solved by technology

When used in anti-flying spraying operations, the synergistic effect of oily solvents and lipophilic solvents ensures that the mixed system has relatively weak volatility, which can improve the anti-evaporation performance of the droplets, and at the same time enhance the dispersion uniformity of the droplets and enhance the stability of the droplets. Settling penetration performance and anti-drift performance, but the surface tension of the liquid is relatively large
That is to say, the anti-flying additives in the prior art are based on sacrificing the wetting performance of the liquid medicine, increasing its anti-evaporation and anti-drift properties, which is not conducive to the function of the liquid medicine

Abstract

The invention provides an aerial control auxiliary agent, and a preparation method and applications thereof, and belongs to the technical field of pesticide auxiliary agents. The auxiliary agent includes, by weight, 20-80 parts of modified vegetable oil, 1-5 parts of a fluorocarbon surfactant, 5-15 parts of ethoxy modified polytrisiloxane, 1-10 parts of limonene, 5-10 parts of an emulsifier, and 14-65 parts of glycerol. The modified vegetable oil is fatty acid methyl ester and / or fatty acid ethyl ester formed through the esterification of one of soybean oil, rapeseed oil, peanut oil and castoroil. Through the cooperation usage of the modified vegetable oil, the fluorocarbon surfactant, the ethoxy modified polytrisiloxane, the limonene and the emulsifier, the auxiliary agent can reduce thevolatilization rate of a liquid medicine, the proportion and droplet size of the liquid medicine can be increased, and the auxiliary agent can have good anti-drift performance; the liquid medicine can have small surface tension, and wettability can be enhanced; and in addition, the auxiliary agent can have good stability by mixing with pesticide diluent, and pesticide effects can be increased.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, in particular to a fly control adjuvant and its preparation method and application. 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, which belongs to low-volume or ultra-low-volume spraying. However, there are still some problems to be solved urgently in agricultural low-altitude spraying. Insufficient, the liquid medicine is easy to precipitate, and the liquid medicine is easy to drift during the spraying process. However, the mist drift of pesticide droplets is very harmful, and it is easy to cause drug damage, environmental pollution, and loss of pesticides; and the effective utilization rate of pesticides is low. [0003] Flying anti-spray additives can solve this problem and become...
