Abstract

The invention relates to the technical field of pesticides, in particular to a diatomite-beauveria bassiana pesticide composition and application thereof. According to the invention, the diatomite-beauveria bassiana pesticide composition is prepared by compounding diatomite with a specific zigzag structure and beauveria bassiana; the insecticidal composition is good in pesticide effect and wide ininsecticidal range, and has good pesticide effects on various pests such as citrus red spiders, citrus scale insects, frankliniella occidentalis, whiteflies, liriomyza sativae, prodenia litura, tea lesser leafhoppers, tea yellow thrips, tea geometrids, green plant bugs and grape aphids. Besides, the diatomite-beauveria bassiana wettable powder is further prepared by adopting a specific wetting agent and a dispersing agent, and the prepared diatomite-beauveria bassiana wettable powder is relatively good in wetting property and spreading property, relatively high in suspension rate and relatively short in wetting time.

Description

technical field [0001] The invention relates to the technical field of pesticides, more specifically, the invention relates to a diatomaceous earth-beauveria bassiana pesticide composition and its application. Background technique [0002] Pesticides refer to chemical synthesis or sources used to prevent, eliminate or control diseases, insects, grasses and other harmful organisms that endanger agriculture and forestry, and to regulate, control, and affect the metabolism, growth, development, and reproduction of plants and harmful organisms. A substance or a mixture of several substances and its preparations produced by biology, other natural products and applied biotechnology. Specifically refers to pesticides used in agriculture to control diseases and insect pests, regulate plant growth, and kill weeds. Among them, pesticides such as organophosphates, carbamates, and pyrethroids are mainly used to kill insects. However, such drugs not only pollute the environment and des...
