Abstract

The invention belongs to the field of pesticides, in particular to a pesticide composition containing matrine and kasugamycin. The composition is compounded with matrine and kasugamycin as main components and added with auxiliary agents, and the preparation form is water, suspension or wettable powder. The composition contains matrine 0.1-4%, kasugamycin 0.5-10%, and the rest are auxiliary agents. The composition utilizes the obvious synergistic effect after compounding matrine and kasugamycin, and is widely used in the prevention and control of various pathogens in crops. It has both protective and therapeutic effects on crops, and is safe for people and the environment. It is not suitable to produce drug resistance and is an ideal pollution-free fungicide.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a pesticide composition containing matrine and kasugamycin. Background technique [0002] Matrine refers to a series of alkaloids extracted from the roots, plants, and fruits of Sophora flavescens and Sophora flavescens by organic solvents, mainly including matrine monoalkaline, oxymatrine, hydroxymatrine Ginseng, Cynicine, Sophoramine, Sophocarpine, Sophoridine, etc., with the highest content of matrine monoline and oxymatrine. Matrine is widely used in medicine, and has various pharmacological effects such as anti-tumor, anti-arrhythmia, anti-inflammation, immune function regulation, and anti-parasite. In agricultural applications, matrine also has a good control effect on downy mildew, gray mold, scab and anthracnose stem rot of various crops. According to Feng Juntao et al.'s report: 0.1mg / L matrine acetone extract has 93.2%, 99.2% and 90.8% inhibition rate on mycelial growth of w...
