Abstract
The invention discloses a plantpesticide and preparation method thereof, wherein the raw material of the plantpesticide comprises tea waste matter, prickly ash seed and bark, dry tobacco leaf and branch, sulfurpowder, medicinal evodia fruit or the like. The temperature and operation time are rigidly controlled using different method according to different medical properties and constituents of various plant herbal medicines and the effective ingredients are extracted to produce the pesticide and then the pesticide is diluted using a special diluent formed by Siberian Cocklebur tree, cuckoo-bud grass, joint vetch, polygonum hydropiper, dogbane and bead tree to be used for plant and cropper disinsection and insect prevention to replace the chemical pesticide with disinsection rate of above 96%.
Description
technical field [0001] The invention relates to a pesticide made from plants, and also relates to a preparation method of the plant pesticide. Background technique [0002] There are many kinds of life in nature. As the climate warms, temperature and humidity create favorable conditions for the reproduction and development of organisms, especially various plant pests; the rapid development of human beings and the increasing variety of food have created many sources of pollution. The destruction of the natural ecological environment has aggravated the development and regeneration of various pests. Since ancient times, humans have used plants and Chinese herbal medicines to decoct water to kill insects and pests. With the development of science, people have invented the method of using high-efficiency toxins of chemical pesticides to kill insects and pests. Chemical pesticides contain high toxins. They are used to kill insects on crops and vegetables, and are easily absorbed ...
