Novel wheat pesticide and preparation method thereof

Abstract

The invention discloses a novel wheat pesticide and a preparation method thereof. The novel wheat pesticide comprises the following components in parts by weight: 70-90 parts of herba artemisiae capillariae, 30-40 parts of achnatherum inebrians, 30-50 parts of flos caryophyllata, 50-70 parts of stem of oriental bittersweet, 10-20 parts of Chinese honey locust powder, 10-20 parts of herba agrimoniae, 15-40 parts of herba polygoni salicifolii, 20-40 parts of Chinese tallow leaves, 10-30 parts of tuberculate speranskia herb and 10-20 parts of herba andrographitis. The novel wheat pesticide is prepared from the above components through four steps of raw material treatment, soaking in warm water, boiling and cooling and purification with ethanol. As the pure plants are adopted as raw materials, the novel wheat pesticide is green and pollution-free, has no chemical residues, causes no harm to the environment and no injury to people, and can effectively prevent and control diseases and pests of wheat, the economic profit is increased and the production cost is lowered.

Description

technical field [0001] The invention belongs to the field of wheat insecticides, and in particular relates to a novel wheat insecticide and a preparation method thereof. Background technique [0002] Wheat is the second largest food crop in the world, after corn, and rice is the third.
