Compound pesticide containing chromafenozide and cyhalodiamide and application thereof

Abstract

The invention discloses a compound pesticide for preventing and treating cnaphalocrocis medinalis, and belongs to the technical field of pesticides. Active ingredients contained in the compound pesticide include chromafenozide and cyhalodiamide, and the weight ratio of the chromafenozide to the cyhalodiamide is 1:20 to 20:1. According to the compound pesticide for preventing and treating the cnaphalocrocis medinalis, due to the pesticide form compounded by the chromafenozide and the cyhalodiamide, the obvious effect on the cnaphalocrocis medinalis is achieved; parts of medium-high-toxicity pesticides can be replaced, the use quantity can be reduced, and environment pollution and residues on agricultural products can be reduced; the compound pesticide has the advantages of being high in pest killing speed and long in lasting period; compared with a single pesticide, cost can be reduced, and resistance can be delayed; the compound pesticide is safe for crops, natural enemies and the environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a compound insecticide containing cyantraniliprole and cyantraniliprole and an application thereof. Background technique [0002] The rice leaf roller belongs to the family Lepidoptera and is one of the common pests of rice. Injury at the tillering stage of rice affects its normal growth; damage in the middle and late stages affects the yield more obviously, especially the flag leaf damage in the later stage, resulting in an increase in grain rate and serious loss. In the Jianghuai rice region of China, the rice leaf roller has 3 to 4 generations per year, and each generation has 3 to 4 peaks due to the immigrant generation and the change of local temperature, which makes the occurrence of the rice leaf roller It is difficult to predict the generation and occurrence period. At present, nereistoxins (monosultap, dimehypo, etc.) and organophosphorus (chlorpyrifos, ...
