Abstract

The invention belongs to the technical field of pesticides, and in particular relates to a preparation method and an application of a Bacillus mortis suspension agent for killing citrus pest mites. The suspending agent is Bacillus death valley ( Bacillus vallismortis ) NBIF‑001 fermentation broth mixed with sodium lignosulfonate, xanthan gum, potassium sorbate, and ethylene glycol. The suspending agent prepared by the invention has a good acaricidal effect on citrus spider mites and rust ticks, is a highly efficient biological pesticide, and has good application and popularization prospects.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a preparation method and an application of a Bacillus mortis suspension agent for killing citrus pest mites. Background technique [0002] All kinds of pest mites of citrus belong to Arachnida, mainly including three families: spider mites, gall mites and tarsal mites. Common spider mites in China include Panonychus citri, Eotetranychus kankitus and Schizotetranychus baltazarae. Gall mites include the citrus rust tick (Eriophyes oleivorus). Polyhagotarsonemus latus has side polyhagotarsonemus latus. The above pest mites suck with piercing-sucking mouthparts. It is harmful to a wide range of hosts, such as citrus, loquat, grape, cherry, peach, pear, strawberry, etc., especially to citrus. Spider mites mainly damage the leaves, twigs, young fruits, flower buds and other parts of the host, especially young leaves and shoots. The affected part fades green first, a...
