Imidaclothiz compound insecticide for shielding and protecting bees and preparation method thereof

Abstract

The invention discloses an imidaclothiz compound insecticide for shielding and protecting bees and a preparation method thereof. The dosage form of the insecticide is water-dispersible granules, an emulsifiable concentrate or a suspending agent, and the insecticide is composed of the following raw materials in percentage by mass: 0.6-70% of main agent and 30-99.4% of adjuvant, wherein the main agent is composed of the following components: mebendazole and imidaclothiz in a mass ratio of (0.1-20):(0.5-50). The preparation method comprises the following steps: weighing the main agent and the adjuvant according to the ratio, and conducting mixing and granulating to obtain the water-dispersible granules of the insecticide; after heating, conducting even mixing under stirring to obtain the emulsifiable concentrate of the insecticide; weighing the main agent and the adjuvant according to the ratio, uniformly mixing the main agent with a dispersing agent, a wetting agent, an emulsifier, an antifreezing agent and a solvent, conducting sand grinding, adding a thickener, and then conducting uniform mixing again to obtain the suspending agent of the insecticide. According to the invention, the compound preparation of mebendazole and imidaclothiz is prepared, thus mebendazole marks the compound preparation, when the compound preparation is applied to, mistakenly applied to or used to conduct drift treatment on flowers, bees are repelled, and the effect of shielding and protecting bees is achieved, so that the insecticide is low-toxic or even non-toxic to bees.

Description

technical field [0001] The invention relates to the technical field of pesticides and insecticides, in particular to a chlorothialine compound insecticide for shielding and protecting honeybees and a preparation method thereof. Background technique [0002] In recent years, bees have become non-target victims of pesticides, especially insecticides, and a large number of bees have disappeared in many countries and regions. Since entering the 21st century, the number of bees in Europe has decreased by 10-30%, the United States has decreased by 30%, and the Middle East has dropped by 85%. Similar phenomena have also appeared in Canada, India, Brazil and Taiwan. . 68% of the world's flowering plants are pollinated by bees. Without bee pollination, about 40,000 species of plants will have difficulty in breeding. Among the 1300 kinds of crops, 70% are pollinated by bees. If the number of bees is insufficient, it will directly affect the yield and survival of crops. According to...
