Abstract

The invention discloses a compound type botanical pesticide and a manufacturing method and application thereof. The compound type botanical pesticide comprises, by weight, 5-35 parts of crofton weed, 1-20 parts of fragrant eupatorium herb, 1-20 parts of lantana camara, 20-35 parts of solvents, 1-5 parts of cosolvents, 1-5 parts of synergistic leveling agents, 0.5-10 parts of stabilizing agents, 0.5-5 parts of surfactants and 20-70 parts of water. The manufacturing method comprises washing clean and grinding the crofton weed, the fragrant eupatorium herb and the lantana camara, respectively placing the crofton weed, the fragrant eupatorium herb and the lantana camara in the solvents, soaking for 5-7 days, and obtaining essential oil extracts of the crofton weed, the fragrant eupatorium herb and the lantana camara, evenly mixing and heating the essential oil extracts, adding the surfactants, the stabilizing agents and the water, and obtaining the compound type botanical pesticide after uniform mixing. The compound type botanical pesticide and the manufacturing method have the advantages that foreign invasive species serve as a main raw material for preparation, effective control of the foreign invasive species is achieved, the harm is turned into a benefit, a pesticidal function is achieved, the problem of pesticide resistance of pests for ordinary pesticides is effectively solved, and environmental pollution is avoided. The compound type botanical pesticide and the manufacturing method have the advantages of being simple in preparation process, practical and convenient simultaneously.

Description

technical field [0001] The invention relates to a composite plant-derived insecticide, a preparation method and application thereof. Background technique [0002] Traditional Chinese medicinal materials, food and tobacco are often attacked by diseases and insect pests during the storage period, resulting in huge losses. The use of insecticides is a relatively common means of modern insect control, but the traditional chemical insecticides are used in large quantities, which not only lead to the resistance of pests, but also cause serious environmental pollution and social impact, and remain on storage materials and storage equipment Pesticides exceed the standard and directly affect human health. Using non-polluting and harmless plants as pesticides is an important development direction of pesticides. In recent years, many countries and enterprises have been continuously researching. [0003] The use of alien invasive species to prepare insecticides is an important measure...
