Pesticide for preventing and treating sugarcane borers

Abstract

The invention relates to the technical field of pesticides, in particular to a pesticide for preventing and treating sugarcane borers. The invention relates to an insecticidal composition for preventing and treating sugarcane borers. The active component of the insecticidal composition is prepared by binary compounding of tenvermectin, flupyradifurone, thiocyclam or chromafenozide, wherein the mass ratio of the tenvermectin to the flupyradifurone is (1-5): (40-1); the mass ratio of the tenvermectin to the thiocyclam is (1-20): (30-1); the mass ratio of the tenvermectin to the chromafenozide is (1-40): (20-1). The components are reasonable, and after compounding, the activity is not simple superposition of the activities of all the components, but has a remarkable synergistic effect. Compared with a single agent, the insecticidal effect can be improved, meanwhile, the insecticidal spectrum can be expanded, and the problems existing when a single-component insecticide is used for preventing and treating sugarcane stem borers can be effectively solved. And the insecticidal mechanisms of the two active components are different during compounding, so that the generation of pest resistance to drugs can be delayed, and the pesticide has a certain protection effect on the pesticide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an insecticide for controlling sugarcane borers. Background technique [0002] Sugarcane is the main economic crop in Guangxi. Sugarcane borer and sugarcane tortoise are two main pests in sugarcane producing areas in Guangxi, and the damage to sugarcane by sugarcane borer is particularly prominent. Sugarcane borer is harmful throughout the whole growth period of sugarcane. It damages the growth point at the seedling stage and causes dead seedlings. The dead heart rate is generally 10% to 20%, and it is more than 50% in severe cases. In the middle and later stages, the borer damages the cane stem and destroys the cane stem tissue. , hindering the growth of sugarcane, causing wind breaks, reducing yield and sugar content, sugarcane is damaged by various stem borers throughout the growth process, and the loss is about 0.25-0.5t per 0.067ha. . Since October 31, 2013, due to the ...
