Problems solved by technology

For example, a company in the United States provides a toxin from the seeds of the tropical plant Neem to make an insecticide, which can effectively control small whiteflies and more than a hundred other pests, but the source of this raw material is extremely limited. Low yield, such as the insecticide developed by Pyrethrum in Africa, due to uneconomical land use and low yield, Japan and other producing areas have given up planting, and now the barren mountainous areas in Africa are planted, and the output is limited
Although "a wettable plant insecticide powder" (Chinese patent application number 00122074.8) selects some natural plants, such as rhizome plants such as Lei Gongteng, Sophora flavescens, and Snake Teng, these plants need 3-5 years to grow and have a drug effect. It is also subject to certain restrictions, which has affected production and development

Abstract

The pesticide power of macleaya cordata plant is prepared with natural plant material and through sorting, crushing to 60-100 mesh, putting it into a stainless steel reactor, adding water to the stainless steel reactor make material become damp, heating to 40-60 deg.C for 3-5 hr while stirring, then taking out, stoving, and grinding to 300-450 mesh into powder product. The pesticide is used to spray on leaves of crop, mix with seed and treat soil, and has high efficiency, wide pesticidal spectrum, low toxicity and other advantages.

Description

Technical field: [0001] The invention belongs to insecticides, and in particular relates to an insecticidal powder pesticide which is made from natural plants. Background technique [0002] Most of the pesticides currently used to control crop diseases and insect pests are chemical preparations. The second edition of "China Patent News" on June 2, 1993, "Summary of the Development of Pesticide Industry and Patent Status", introduced: In 1990, my country's pesticide products ranked second in the world, producing 156 kinds of pesticides, including 59 kinds of insecticides. There are 9 kinds of acaricides, 3 kinds of fumigants, 7 kinds of rodenticides, 39 kinds of fungicides, 33 kinds of herbicides and 6 kinds of plant growth regulators. Most of these pesticides are chemical agents. Such as methomyl, dimethomyl, beta-permethrin, monocrotophos, dimethoate, phoxim and other chemical preparations. The long-term use of these chemical preparations makes the disease resistant to pes...
