Abstract

The invention provides an insecticidal composition containing pirimiphos-methyl and a preparation method thereof. In the composition, an organophosphorus insecticidal and acaricidal agent pirimiphos-methyl with the advantages of high efficiency, low toxicity, quick effect and the like and a novel insecticide pyriproxyfen of juvenile hormone analogue are used in compatibility, so that while effectively killing pests and worm eggs, the composition also can effectively control the generation of pest resistance to insecticide, and realizes long-lasting insecticidal effect. At the same time, the composition provided by the invention can be prepared into an effervescent tablet or spreading oil, thus avoiding the problems of flammability, easy leakage, irritation, environmental pollution and the like in existing insecticidal composition dosage forms. The insecticidal composition provided by the invention has the advantages of good insecticidal effect, long duration, and good use safety, etc. According to the method provided by the invention, the components are adopted as the raw materials, and are further mixed to prepare effervescent tablets or spreading oil, the preparation method is convenient, and the prepared insecticidal composition has the advantages of good insecticidal effect and long duration, etc.

Description

technical field [0001] The present invention relates to an insecticidal composition, in particular to an insecticidal composition containing pirimiphos-methyl and a preparation method thereof. The insecticidal composition of the present invention can be used for household sanitation, public health, crop insecticide and grain storage, etc. in the field. Background technique [0002] Pesticide is a medicine used to control agricultural pests and household urban sanitation pests. It has a long history of use and there are many varieties of pesticides. With the rapid development of agriculture, the widespread use of pesticides and the amount of pesticides used have shown an increasing trend year by year. [0003] Most of the commonly used insecticides use pyrethroids, organophosphorus or carbamate compounds as active ingredients. Due to the long-term use and the difficulty in standardizing the use of insecticides containing the above-mentioned active ingredients, the pest popu...
