Abstract

The present invention belongs to the technical field of pesticides, and relates to a pesticide composition comprising tetramycin and tea saponin. The composition is characterized in that the tetramycin and the tea saponin are compounded so as to reduce a use amount of the tetramycin and delay drug resistance generation, and a mass ratio of the tetramycin to the tea saponin is 1:0.01-1:100, preferably 1:0.1-1:50, and more preferably 1:1-1:10. According to the present invention, rice blast can be effectively prevented and controlled after the tetramycin and the tea saponin are compounded.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a synergistic pesticide composition of tetramycin and tea saponin. Background technique [0002] Rice blast is one of the important diseases of rice. Together with rice sheath blight, rice false smut, and rice virus disease, it is called the four major diseases of rice. The disease is widely distributed and occurs in more than 80 countries and regions around the world. It also occurs in the north and south rice regions of my country. In areas where the disease is endemic, the yield is generally reduced by 10% to 20%, and in severe cases it can reach 40% to 50%. Especially heavy fields may even fail to harvest. At present, the pesticides used against rice blast mainly include chemical pesticides such as tricyclazoles, prochloraz, and bromochloride. These chemical pesticides are prone to problems such as pesticide residues, environmental pollution, and resistance. [0003] Tetr...
