Abstract

The invention discloses a clothianidin compound insecticide for shielding and protecting bees and a preparation method thereof. The insecticide is prepared in the form of water dispersible granules, granules, emulsifiable concentrate or wettable powder, and consists of the following raw materials in percentage by mass: 0.6-60 percent of a main agent and 40-99.4% of an auxiliary agent. The main agent consists of the following active ingredients in mass ratio: nimbin oil: clothianidin=0.1-10:0.5-50. The preparation method comprises the following steps: weighing the main agent and the auxiliary agent according to the proportion, mixing and granulating to obtain the insecticide water dispersible granules, repeatedly squeezing, stirring, tabletting, pressing, drying, rolling and crushing to obtain the insecticide granules, heating, stirring and mixing uniformly to obtain the insecticide emulsifiable concentrate, and fully mixing and crushing to obtain the pesticide wettable powder. According to the clothianidin compound insecticide, the neem oil and the clothianidin compound preparation are prepared, and the neem oil is used for marking the flowers which are applied, misapplied or drifted by the compound preparation, so that the bees can be shielded and protected by repelling the bees, and the clothianidin compound insecticide having low toxicity and even no toxicity to the bees areachieved.

Description

technical field [0001] The invention relates to the technical field of pesticides and insecticides, in particular to a clothianidin composite 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 ...
