Abstract

The invention discloses a spinosyn and avermectin composite polymeric micellar pesticide. The spinosyn and avermectin composite polymeric micellar pesticide is mainly prepared from the following components: 10 parts of spinosyn, 8-12 parts of avermectin, 140-160 parts of hydrophilic material and 140-160 parts of hydrophobic material. Compared with the prior art, the prepared spinosyn and avermectin composite polymeric micellar pesticide has the characteristics of strong efficacy and long-lasting effect, can effectively kill pests, including lepidoptera, diptera and thysanoptera pests, and has a certain poisoning and killing effect on certain specific types of coleoptera, orthoptera, hymenoptera, isoptera, siphonaptera, dermaptera and corrodentia pests.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to a spinosyn and abamectin composite polymer micelle pesticide, which is applied in the agricultural field. Background technique [0002] Biological pesticides refer to living organisms and their metabolites and transgenic products that are used to control diseases, insects, grasses and other harmful organisms, and can be made into commercial biological preparations, including bacteria, viruses, fungi, nematodes, plants, insect natural enemies, Agricultural antibiotics, plant growth regulators and transgenic plants resistant to diseases, insects 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 have paid more and more attention to the sustainable development of agricultural production and the coordination between humans and the environment, especia...
