Pesticide composition for preventing and treating noctuid and preparation method of pesticide composition

Abstract

The invention discloses a pesticide composition for preventing and treating noctuid. The pesticide composition comprises the following components in percentage by weight: 5%-10% of chlorfenapyr, 10%-18% of tolfenpxrad, 3%-8% of tea saponin, 8%-15% of imidaclothiz, 1.0%-3.0% of an ether dispersant, 2.0%-3.5% of a salt dispersant, 12%-20% of ethyl acetate, 3%-8% of cyclohexanone, 4.5%-7.5% of a wetting agent, 0.1%-0.8% of an antifoaming agent, 1%-8% of an antifreezing agent, 0.03%-0.10% of a preservative and the balance of distilled water. The pesticide composition for preventing and treating noctuid disclosed by the invention is good in insecticidal efficacy, and does not need to be alternately used with other medicines. The invention further provides a preparation method of the pesticide composition for preventing and treating noctuid. The method is simple in process and suitable for popularization.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition for controlling noctuid moths, and also provides a preparation method of the aforementioned pesticide composition for controlling noctuid moths. Background technique [0002] Fenpyramid, chemical name: 4~chloro~3~ethyl~1~methyl~N~{[4~(4~methylphenoxy)phenyl]~methyl}~1H pyrazole~5~ Carboxamide is a pyrazole heterocyclic insecticide and acaricide. Its main mechanism of action is to prevent the oxidative phosphorylation of insects, and it also has the functions of killing eggs, inhibiting feeding, inhibiting oviposition and bactericidal. [0003] Chlorfenapyr, chemical name: 4~bromo~2~(4~chlorophenyl)~1~(ethoxymethyl)~5~(trifluoromethyl)pyrrole~3~nitrile, is a The insecticide precursor itself has no poisonous killing effect on insects. After insects feed or contact with chlorfenapyr, in the insect body, chlorfenapyr is converted into a specific insecticidal active...

AI Technical Summary

Problems solved by technology

[0004] At present, the above two substances are widely used in insecticide, and some patents have made some explanations on the combination of the two, but in actual application, considering the insecticidal properties of the drug, the above two Although this kind of medicine has a larger insecticidal range, it is still limited. In order to achieve a good insecticidal effect, it is still necessary to use the above-mentioned medicines to interact with other insecticides at intervals to achieve better insecticidal effects. effect, but how to choose the best interactive insecticidal drug is a difficult problem for users, which brings inconvenience to operation

[0005] In addition, although the existing patents have made instructions on the combination of the above-mentioned drugs, from the perspective of insecticidal effect, there is still room for improvement.
