Description

technical field [0001] The invention relates to the technical field of crop insecticides, in particular to a method for preparing insecticides for preventing and controlling water spinach pests in greenhouses. Background technique [0002] Greenhouse vegetables refer to the vegetables planted on the greenhouse covered with plastic film. It is one of the effective means to increase farmers' income by artificially creating a suitable ecological environment, adjusting vegetable production seasons, adjusting market demand, and promoting high-quality and high-yield vegetables.

Problems solved by technology

[0003] Existing technology, such as China's invention authorized patent, application number is 201310510742.4, a plant-derived vegetable pesticide and its production method, its raw materials and parts by weight include: 20-30 parts of pyrethrum, 20-30 parts of Sophora flavescens, spicy 20 to 30 parts of Polygonum, 10 to 15 parts of Cnidium, and 5 to 10 parts of Sapindella fruit. The production method is to smash pyrethrum, Sophora flavescens, spicy Polygonum, Cnidium, and Sapindella fruit into pieces, and add 5 to 10 times the water , boil for 30-50 minutes, filter, add 3-5 times of water to the filter residue and boil for 20 minutes, combine the two filtrates to obtain the product, dilute the product by 300-500 times and spray, which can effectively control aphids, armyworms, diamondback moths, cabbage Pests such as caterpillars and rice planthoppers, but the insecticide may degrade slowly after spraying on the surface of vegetables or soil, and there is still room for improvement in the degradation of insecticides
