Abstract

The invention provides a daubing type microbial powder, a preparation method and application thereof in control of tree diseases and insect pests. The daubing type microbial powder is formed by mixingof the following raw materials by mass percentage: 3%-40% of microbial agent original drug, 2%-20% of nutrients, 1%-10% of a dispersant, 2%-20% of a binder, 1%-5% of an auxiliary material, and the balance filler. The invention provides a brand new daubing type microbial agent product, the daubing type microbial agent product provided by the invention not only has good bactericidal and insecticidal effects, but also can maintain long-acting and stable bactericidal and insecticidal activity in intense illumination and other external environments. In addition, the production process is simple, low in cost, and convenient for use, and the metabolites produced by microorganisms have a repair effect on tree damages.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, and in particular relates to a smear-type microbial powder, a preparation method thereof and an application in preventing and treating tree diseases and insect pests. Background technique [0002] Microbial pesticides refer to the use of living microorganisms and their metabolites to prevent and control agricultural pests and diseases. They have strong selectivity, are safe for humans, livestock, crops and the natural environment, and are not easy to produce drug resistance. Therefore, they have been extensively studied. At present, there are relatively mature microbial agent products on the market. [0003] With the rapid development of economic globalization, my country will face increasingly stringent pesticide residue standards in international agricultural products and food trade, which requires my country's agricultural products to gradually transition from traditional plantin...
