Problems solved by technology

[0003] Since mirid bugs have always mainly harmed cotton in China, the main research has also focused on cotton field mirid bugs. In view of the current mirid bugs that are harmful to fruit trees, there are relatively few systematic studies on them, and the control techniques are mainly chemical control. , and then due to long-term use, mirid bugs have developed resistance to various types of insecticides, therefore, seeking new types of mirid bug killing agents is worth further research

Abstract

The invention discloses a fruit tree miridae pesticide which is characterized in that the pesticide is mainly composed of the components of: 2 parts of benzoylurea, 1-5 parts of bifenthrin, 1-5 parts of thiamethoxam, 30-40 parts of pyrethrum, 20-40 parts of snakegourd root, 30-50 parts of rehmannia root, 10-20 parts of rangooncreeper fruit, and 10-20 parts of chinaberry bark. The invention also discloses a preparation method of the fruit tree miridae pesticide. Compared to prior arts, the fruit tree miridae pesticide provided by the invention is harmless to human and livestock, and causes no phytotoxicity to crops. The pesticide has long-lasting period, and can effectively kill fruit tree miridae. With the fruit tree miridae pesticide, pesticide efficacy can be improved, the possibility of miridae pesticide resistance can be reduced, and environment pollution can be reduced.

Description

technical field [0001] The invention relates to an insecticide, in particular to a high-efficiency composite insecticide containing natural extracts and various insecticides, which is applied in the field of agriculture. Background technique [0002] There are many kinds of mirid bugs, which are widely distributed and are worldwide agricultural pests. They can harm cotton, fruit trees, vegetables, tea, mulberry, strawberries, pastures, sunflowers and other crops and economic plants. In the past ten years, with the large-scale promotion of genetically modified cotton in China, the population of mirid bugs has exploded in cotton areas, and there have been a large number of reports about the damage of fruit trees by mirid bugs, and the scope has spread to large fruit tree planting areas such as North China, East China, and Northwest China. The objects of harm also involve most of the fruit tree varieties in the north. The existing research results show that the degree of harm o...
