Abstract

The invention discloses an aqueous emulsion composition containing bactericide 1-o-hydroxyphenyl-butanone and preparation method thereof. The aqueous emulsion is formed by dissolving or melting 1-o-hydroxyphenyl-butanone, surfactant, thickener, antifreezing agent, deionized water, homogenizing, dispersing. The majority of the emulsion is water, in addition to effective component, the content of organic solvent is few or none. The environmental protection type pesticide formulation is safe in transmission and utilization and no pollution to the environment. The formulation has good prevention effect to multiple diseased on food crops, fruit trees, vegetables, cottons or the like.

Description

technical field [0001] The invention relates to a composition containing a bactericide fenoxyfen aqueous emulsion and a preparation method thereof, belonging to the field of agricultural chemicals. technical background [0002] For a long time, due to the extensive use of chemical pesticides, it not only polluted the living environment, but also caused certain target organisms to develop a certain degree of resistance, resulting in a further increase in the use of chemical pesticides, and incidents of chemical pesticides polluting agricultural by-products and groundwater have occurred from time to time , pose a certain threat to human health. Therefore, the development and utilization of pesticide resources that are harmless to the environment and human beings have attracted more and more attention. Ginkgo is a characteristic plant in my country. It is called a living fossil of plants. It has strong resistance to stress and is not easy to be harmed by diseases and insect pe...
