A kind of preparation method of spinosyn and avermycin composite polymer micelle insecticide

Abstract

The invention discloses a preparation method for a spinosad / avilamycin composite polymeric micelle insecticide. The insecticide is mainly composed of the following components: in parts by weight, 10 parts of spinosad, 8-12 parts of avilamycin, 140-160 parts of a hydrophilic segment material and 140-160 parts of a hydrophobic segment material. Compared with the prior art, the obtained spinosad / avilamycin composite polymeric micelle insecticide has the characteristics of strong drug effect and long persistent period. The spinosad / avilamycin composite polymeric micelle insecticide is capable of effectively killing insects comprising lepidoptera, diptera and thysanoptera insects, and also has poisoning effect on certain specific kinds of insects in coleoptera, orthoptera, hymenoptera, isopteran, siphonaptera, dermaptera and corrodentia.

Description

technical field

[0001] The invention relates to a preparation method of a biological pesticide, in particular to a preparation method of a spinosad and avermectin composite polymer micelle insecticide, which is applied in the field of agriculture. Background technique

[0002] Biopesticides refer to living organisms and their metabolites and genetically modified products used to prevent and control harmful organisms such as diseases, insects, and grasses, and can be made into commercial biological source preparations, including bacteria, viruses, fungi, nematodes, plants, natural enemies of insects, Agricultural antibiotics, plant growth regulators and transgenic plants resistant to diseases, insect pests and weeds, etc. Biological pesticides have been used in agricultural production for half a century, but the development has been relatively slow due to various reasons. In recent years, people pay more and more attention to the sustainable development of agricultural produ...
