A kind of anti-fly additive and its preparation method and application

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.

Examples

preparation example Construction

[0027] The present invention also provides a preparation method of the anti-flying additive described in the above-mentioned technical scheme, comprising the following steps:

[0028] Mix modified vegetable oil, limonene, ethoxy-modified polytrisiloxane, emulsifier and glycerol in parts by weight to obtain an initial mixture; add a fluorocarbon surfactant to the initial mixture to obtain an antifly Auxiliary.

[0029] In the present invention, there is no special limitation on the mixing method of the modified vegetable oil, limonene, ethoxy-modified polytrisiloxane, emulsifier and glycerol, as long as the above-mentioned substances are mixed uniformly.

[0030] In the present invention, adding the fluorocarbon surfactant to the initial mixture is preferably accompanied by stirring; the stirring speed is preferably 30 r / min; the stirring time is preferably 30-60 min.

[0031] In the present invention, other raw materials except the fluorocarbon surfactant are mixed first, and...
