Abstract

The invention relates to a biocide and the preparing method. Said biocide comprises: avermectin 1.1- 1.5%, neem 0.05- 0.5%, auxiliary agent 2- 25%, packing material 73.5- 97.8%, the proportion is weight proportion; auxiliary agent and packing material are added into avermectin and neem to produce suspending agent; the auxiliary agent of said suspending agent comprises wetting dispersing agent 1- 15%, anti- freezing agent 1- 3%, thickening agent 0.05- 2%, and defoaming agent 2- 5%. The biocide is widely used in rice, fruit trees and vegetable for insects prevention, and is characterized by low cost, good effect, convenient production and building effect to prevention object.

Description

technical field [0001] The present invention relates to a biopesticide and its preparation method, in particular to a biopesticide compounded with synergistic plant sources and antibiotics and its preparation method Background technique [0002] As we all know, as the problem of pesticide pollution and people's attention to the living environment become increasingly prominent, it has become a hot topic in the field of formulations to seek to reduce the risks brought about by pesticides and their use through the innovation of formulation technology. After reviewing the issues related to pest resistance management, many pesticide experts pointed out that the uneven distribution of pesticides is caused by the use of technology and inappropriate pesticide formulations; and pesticide use technologies as an essential part of resistance management research. Some studies have pointed out that, based on the actual dosage of pest targets, in the process of large-scale farmland applic...
