Mechanical control spray additive

Abstract

The invention relates to the field of agricultural mechanical control, and particularly relates to preparation and an application of a mechanical control spray additive. The additive is prepared from the following components in percentage by mass: 5-25 percent of ethoxy modified trisiloxane, 15-18 percent of non-ionic anionic compound surfactant, 5-20 percent of glycerinum and the balance of vegetable oil (37-75 percent). The additive can be used for solving the problems that other spray additives cannot solve deposition and spreading problems in mechanical control and improving the prevention effect of mechanical control, is suitable for low-volume spray or super-low-volume spray of airplanes and large spray machinery, such as cannon and the like, and can be used for solving the problems of poor chemical settlement, poor drift resistance and poor spreadability in the mechanical control process.

Description

Technical field: [0001] The invention belongs to the field of pesticide adjuvants, and relates to the proportioning, preparation and application of a mechanized spray adjuvant, which is used for agricultural mechanized spray control. Background technique: [0002] Spray auxiliaries are currently used in the use of pesticides, fertilizers, and sanitary preparations, especially in conventional volumetric spray filtration. They can improve the use effect of products and reduce the dosage by increasing the wetting, spreading and adhesion of products. [0003] At present, the commonly used tank mixing additives in the market are: one is silicone, the other is mineral oil additives, and the third is vegetable oil additives (including methyl esterification of vegetable oil). These additives are widely used in conventional volumetric sprays. . [0004] Conventional volume spraying generally requires a liquid medicine volume of 10-50L / mu. With the increase in labor costs, the devel...

Problems solved by technology

If the amount of liquid medicine required for mechanized control is low, the amount of liquid used for aircraft spraying is 0.3-0.8L / mu, and the amount of liquid used for cannons is 1-3L / mu, which becomes low-volume or ultra-low-volume spray, so low The amount of liquid used is poor with conventional auxiliaries

[0005] There are still few additives that can be used in mechanized spray control (hereinafter referred to as machine defense), and the effect is not ideal. To do a good job in mechanized control, it is necessary to consider the compatibility of additives and equipment. This needs to solve two aspects Problems: How does such a small amount of liquid medicine reach the tyrant mark, how to spread the liquid medicine that reaches the tyrant mark evenly, and if you want to use the liquid medicine to reach the tyrant mark, you need to consider the settlement of the liquid medicine, anti-drift, and anti-volatility and evaporation.
