Abstract

The invention provides a sterilization suspending agent with synergistic interaction and a preparation method thereof. The invention relates to the field of a bactericide combination technology with synergistic interaction. The agent comprises effective components benzothiostrobin and thifluzamide, and also comprises a dispensing and wetting agent, antifreeze, a thickening agent, an antifoaming agent and a filling material; the suspending agent comprises benzothiostrobin whose weight is 2-20% of the total weight of the suspending agent, and thifluzamide whose weight is 1-30% of the total weight of the suspending agent. All materials are added into an enamel stirring tank and uniformly mixed, the materials are crushed or grinded by air-flow and prepared into a suspending agent-liked bactericide containing benzothiostrobin and thifluzamide. Benzothiostrobin and thifluzamide are compounded for usage, the agent has the advantages of low toxicity, few residuals, wide sterilization spectrum, good persistent effect, low cost and nuisanceless control, and the agent is an ideal pesticide for controlling various diseases.

Description

technical field [0001] The invention relates to the technical field of synergistic fungicide combination. Background technique [0002] Rice sheath blight and rice false smut are the main and important diseases during rice growth, with an annual incidence of over 100 million mu, which is a serious obstacle to high and stable rice yields in my country. The realization of pollution-free biological control of rice diseases is the development direction and goal of the field of agricultural plant protection. In recent years, although the state has explicitly prohibited the use of highly toxic pesticides on rice, it is still common to use highly toxic and high-residue pesticides in the actual agricultural production process due to the lack of highly effective disease control agents. Low-residue new pesticides are an inevitable development trend. [0003] Benthiastrobin is an innovative fungicide candidate species with independent intellectual property rights, which can be widely...
