Agricultural auxiliary agent, granules and preparation method of agricultural auxiliary agent and granules

Abstract

The invention discloses a pesticide auxiliary agent containing an organic silicon surface active agent and at least one other surface active agent; the pesticide auxiliary agent is mainly used for a pesticide granule preparation and is used for enabling granules to be rapidly dissolved and dispersed in water and enabling the water to be clear and transparent, so that the requirement for the product quality can be met, and pesticide liquid is promoted to be rapidly spread, absorbed and permeated on crops. The invention also discloses the pesticide granule preparation comprising the pesticide auxiliary agent, and a preparation method of the pesticide granule preparation. According to the method, an organic solvent is adopted for evenly mixing in the granulating process, so that the influence on the organic silicon surface active agent caused by excessive water can be avoided.

Description

technical field [0001] The invention relates to an agrochemical composition, specifically a composition containing organic silicon surfactants and other surfactants. The composition is used in herbicide soluble granules to make the granules clear and transparent in water and meet product quality requirements. It is required, at the same time, to improve the rapid spreading, absorption and penetration of the medicinal solution on the crops. Background technique [0002] Silicone surfactants are divided into two categories: spray improvement and activator, which can reduce surface tension, improve the ability of spray liquid to wet biological targets, increase the expansion area of ​​spray liquid on target organisms, and improve the penetration ability of liquid medicine, thereby improving Resistance to rain erosion. Since Monsanto New Zealand successfully applied the first commercial silicone surfactant L-77 in the field of pesticides in 1985, silicone surfactants have been ...

Problems solved by technology

Moreover, the currently disclosed compositions containing silicone surfactants are not suitable for herbicide soluble granules, because after being diluted in water, the diluent is in the form of an emulsion, which cannot ensure that the diluent is clear and transparent, and even has suspended matter or oily Precipitation

Therefore, there is currently no adjuvant containing silicone surfactants that can meet the requirements for pesticide soluble granules. The existing practice is to use silicone adjuvants and pesticide soluble granules in a tank-mixed manner. However, when tank mixing is used, the proportion will be inaccurate when farmers use it, and the mixing effect will be poor, which will affect the efficacy of the medicine and is not convenient to use.
