A kind of preparation method of spinosad and griseofulvin composite microcapsule insecticide

Abstract

The invention discloses a preparation method for a spinosad / griseofulvin composite microcapsule insecticide. The composite microcapsule insecticide comprises the following components in parts by weight: 10 parts of spinosad, 5-15 parts of griseofulvin, 100-200 parts of a carrier material, 1-2 parts of a coagulant, 0.5-1 part of a cross-linking agent and 1-2 parts of a plasticizer. Compared with the prior art, the prepared spinosad / griseofulvin composite microcapsule insecticide has the characteristics of stability, strong drug effect and long persistent period. The spinosad / griseofulvin composite microcapsule 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 biological pesticide, in particular to a preparation method of a spinosad and griseofulvin composite microcapsule 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 production and the coordinatio...
