Problems solved by technology

[0003] The control methods for wheat leaf rust are mostly based on the selection of disease-resistant varieties and chemical control. The use of chemical fungicides can easily cause pathogenic bacteria to develop resistance, pollute the environment, and endanger the ecological balance. They have good control effects, non-toxicity, and no pollutio

Abstract

The invention relates to paenibacillus polymyxa for controlling puccinia triticina of wheat and an application of the paenibacillus polymyxa and belongs to the technical field of microbial pesticides.The bacterial strain paenibacillus polymyxa is preserved in CGMCC (China General Microbiological Culture Collection Center) with preservation number being CGMCC No.14879 on November 14, 2017. An antibiological inoculant for controlling puccinia recondite of wheat can be prepared from the paenibacillus polymyxa, infection of puccinia recondite of wheat can be controlled effectively, the effect isremarkable, meanwhile, plant growth can be promoted, and the paenibacillus polymyxa has good application prospect in the aspect of control for puccinia recondite of wheat.

Description

technical field [0001] The invention belongs to the technical field of microbial pesticides, and in particular relates to a Paenibacillus polymyxa used for preventing and treating wheat leaf rust and an application thereof. Background technique [0002] Wheat leaf rust, caused by the leaf rust fungus Puccinia triticina, is one of the major diseases in wheat production in the world, and it can reduce wheat yield by more than 40% when it occurs seriously. There have been 4 major outbreaks of wheat leaf rust in the main wheat areas of my country, which caused serious yield loss to wheat production. In recent years, the disease has shown a trend of expansion and development in my country. In 2012, wheat leaf rust occurred in large areas in Gansu, Henan, Shaanxi, Anhui and Sichuan. [0003] The control methods for wheat leaf rust are mostly based on the selection of disease-resistant varieties and chemical control. The use of chemical fungicides can easily cause pathogenic bacte...
