Synergistic insecticidal composition containing clothianidin and pymetrozine, and application thereof

Abstract

The invention relates to a high-efficiency and low-toxicity compound insecticide which consists of clothianidin and pymetrozine and is particularly used for application research on controlling rice plant hopper. The insecticidal composition contains clothianidin and pymetrozine and is prepared from the following raw materials in percentage by weight: 0.1 to 50 percent of clothianidin, 60 to 0.1 percent of clothianidin, and the balance of aids and carriers. The insecticidal composition is applied to the control over various pests such as hemiptera pests, coleopteran pests, diptera pests, certain lepidoptera pests on rice, vegetables, fruit trees and other plant, such as plant hopper and aphid, leafhopper, thrip, cnaphalocrocis medinalis, chilo suppressalis, myzus persicae, black peach aphid, pear psylla, whitefly and the like. Aiming at the conditions of high difficulty in controlling plant hopper and increased resistance in the current market, the clothianidin and the pymetrozine are reasonably compounded according to the control experimental effects of clothianidin on plant hopper, a clothianidin and pymetrozine compounded control composition is researched, the defects that the resistance and a control object of the conventional nicotine products in the current market are single, so control cost is increased due to multiple times of using insecticides are overcome, and the invention provides the insecticidal composition which contains clothianidin and pymetrozine and has the synergistic effects, and application of the insecticidal composition.

Description

technical field [0001] The invention relates to an insecticidal composition with clothianidin and pymetrozine as active ingredients and an application thereof, belonging to the technical field of insecticidal compositions and pesticides. Background technique [0002] The neonicotinoid insecticide Clothianidin is jointly developed by Bayer AG and Takeda Corporation of Japan in the global market. This variety has been used in rice, fruit trees, tea, turf and ornamental crops in Japan. Clothianidin is another neonicotinoid insecticide discovered by Takeda after nitenpyram. It belongs to the second generation. The group replaces the pyridine group; the second is to replace the nitromethylene moiety with nitroimine. The methyl group at position 5 increases the activity against piercing and sucking pests. The 2-chloro-5-thiazolyl heterocycle has a higher effect on chewing mouthparts pests. [0003] Pymetrozine belongs to pyridine or triazinone insecticides. It is a brand-new ...

AI Technical Summary

Problems solved by technology

[0006] In order to avoid the defects of conventional nicotine products in the existing market that have single resistance and control targets, resulting in multiple medications that increase the cost of control, the present invention provides a drug containing two active components of clothianidin and pymetrozine. Insecticidal composition with synergistic effect and its application

[0007] Aiming at the situation that the prevention and control of planthoppers is difficult and the resistance to planthoppers is increased in the current market, the present invention uses the experimental effect of clothianidin on the control of planthoppers, combined with pymetrozine for reasonable compounding, and develops a group of clothianidin and pyrimidae The control combination of ketone compound has a wide insecticidal spectrum, which solves the problem of conventional nicotine resistance and poor effect, reduces the number of medications and protects the environment
