Embodiment Construction

[0030] The present invention will be further described below in conjunction with the examples, but the present invention is not limited thereto.

[0031] Use DPS software for statistical analysis and calculate the LC of each drug 50 , and calculate the co-degree coefficient (CTC value) of the mixture according to Sun Yunpei's method.

[0032] Measured toxicity index (ATI) = (standard drug LC 50 / Test agent LC 50 )×100.

[0033] Theoretical toxicity index (TTI) = toxicity index of agent A × percentage content of A in the mixture + toxicity index of agent B × percentage content of B in the mixture.

[0034] Co-toxicity coefficient (CTC) = [measured toxicity index (ATI) of mixture / theoretical toxicity index (TTI) of mixture]×100.

[0035] According to the classification standard of NY / T11547.7-2006 insecticide joint action: co-toxicity coefficient (CTC) ≥ 120 means synergistic effect; co-toxicity coefficient (CTC) ≤ 80 means antagonism; 80 < co-toxicity coefficient (CTC) )<1...

Abstract

The invention relates to insecticide composition for corn. The insecticide composition for the corn contains a bisamide compound and an anabasine compound and is especially a seed coating agent, wherein the bisamide compound is any one of chlorantraniliprole, cyantraniliprole and tetra-chlorantraniliprole; the anabasine compound is any one of thiamethoxam, imidacloprid, clothianidin and dinotefuran; and the weight ratio of the amide compound to the anabasine compound is (1:10)-(10:1). The insecticide composition for the corn has an obvious synergistic effect on control of athetis lepigone, ostrinia nubilalis and plant hopper and resistance to the insecticide composition for the corn is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to an insecticidal composition for corn containing a bisamide compound and a neonicotinoid compound, the insecticidal composition is in particular a seed coating agent. technical background [0002] Seed coating technology is a new seed treatment technology developed on the basis of traditional seed soaking or seed dressing technology. The seeds in a dry or wet state are coated with a composition such as a pesticide containing a binder, so that a protective layer with a certain function and coating strength is formed outside the seeds. This process is called seed coating, and the coating on the outside of the seeds The composition is a seed coating agent. The seed coating agent absorbs water and swells in the soil without being dissolved, and the pesticide contained in it is released slowly with the germination and growth of the seeds. Therefore, the seed coating agent has the eff...
