Abstract
The invention belongs to the technical field of pesticide and relates to an insecticidal and germicidal composition for paddy rice. The insecticidal and germicidal composition comprises the effective components of chlorantraniliprole and kasugamycin, the content of the chlorantraniliprole is preferably 2% to 20%, and the content of the kasugamycin is preferably 1% to 10%. The compound pesticide overcomes the defect of the original single component, has obvious complementary and synergistic functions, can effectively prevent and treat rice blast and rice leaf rollers simultaneously and is convenient for farmers to use. The insecticidal and germicidal composition has the characteristics of quick acting, broad spectrum and low cost and can be prepared into routine preparations, such as suspending agents, wettable powder, water dispersion granules and the like. The insecticidal and germicidal composition has higher preventing and treating effects and longer effective period, can also reduce the dosage, delays the generation of drug resistance, reduces contamination to the environment and has very good practicability.
Description
technical field [0001] The invention relates to an insecticidal and bactericidal composition for paddy fields, in particular to an insecticide containing chlorantraniliprole and a fungicide composition containing kasugamycin. Background technique [0002] Rice blast is an important disease of rice, which is distributed in all rice producing areas of the country and occurs throughout the rice growth period; rice leaf roller is an important pest of rice, both of which seriously affect rice yield. From June to August every year is the time when rice blast and rice leaf roller occur at the same time, and it is also an important period for rice to control pests and diseases to ensure production. It is urgent to find a medicament that can control both rice blast and rice leaf roller solved problem. [0003] Chlorantraniliprole is a high-efficiency, broad-spectrum, long-lasting o-formamidobenzamide systemic insecticide, chemical name: 3-bromo-N-[4-chloro-2 -Methyl-6-[(methylcarba...
