Abstract

The invention belongs to the technical field of pesticides, in particular to a preparation method of a plant pesticide. According to the preparation method, cucumis bisexualis and white silkworm are used as nutrient supply sources, so that on one hand, nutrients are provided for fermentation, on the other hand, the surfaces of plants are protected, and plants are prevented from being eaten by pests, meanwhile, fermentation is carried out on a mixture containing soybeans and the like by using microorganisms to obtain colloidal substances, and viscosity of the pesticide is improved; then throughthe extraction of plants such as membranaceous marshmarigold, the pest resistance effect is increased; then under the catalysis of titanium dioxide, pest resistance beneficial substances are cross-linked with the colloidal substances through genipin, so that the beneficial substances are released slowly, the validity time is increased, and the frequency of spraying of the pesticide is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a preparation method of a plant pesticide. Background technique [0002] Pesticides are mainly used to control agricultural pests and urban sanitation pests. It has a long history of use, large dosage and many varieties. In the 20th century, with the rapid development of agriculture, pesticides greatly increased agricultural output. However, almost all pesticides seriously alter the ecosystem, most are harmful to humans, and others are concentrated in the food chain. We must strike a balance between agricultural development and the environment and health. According to the source, it can be divided into two categories: biogenic pesticides and chemically synthesized pesticides. The production methods of Bt pesticides mainly include liquid submerged fermentation and semi-solid fermentation. The two-step production method is an effective, simple and practical Bt i...
