A kind of enterobacteriaceae and application for preventing and treating plant root-knot nematode

Abstract

The invention relates to an enterobacter for preventing and treating root-knot nematode and its application. The preservation unit of the enterobacter is the China General Microorganism Culture Preservation Management Center, the preservation number is CGMCC No.16336, and the classification is named Ludwig enterobacterium Bacillus ( Enterobacter ludwigii ); the bacterial agent of the enterobacteriaceae has a control effect on nematodes, and has the purposes of improving plant resistance to nematodes and promoting plant growth; the bacterial agent of enterobacteriaceae proposed by the present invention has excellent control effect on plant root-knot nematodes, and simultaneously It can promote plant growth, improve plant resistance to nematodes, and provide new resources for the development of new seed treatment agents and inducers; the mixed use of Enterobacteriaceae and traditional nematicides has excellent control effect on nematodes and can reduce chemical agents The amount of application can reduce pesticide residues, which is of environmental protection significance.

Description

technical field [0001] The invention belongs to the field of biological pesticides, and in particular relates to an enterobacter for preventing and treating plant root-knot nematodes and its application. Background technique [0002] Plant parasitic nematodes occur and cause damage in many countries and regions in the world, and there are various types. On a global scale, the occurrence and harm of plant parasitic nematodes have become increasingly serious with the development of agriculture and forestry and the changes in farming and cultivation systems. According to Esser statistics, 207 genera and 4832 species of plant parasitic nematodes have been reported to have been found in the world until 1990. Plant-parasitic nematodes are estimated to cause an annual loss of 12.3% of the world's major crops, exceeding US$ 100 billion, while actual losses far exceed estimates, citing the fact that damage caused by many nematodes is limited by the absence of field-visible symptoms o...

Problems solved by technology

At present, the control of plant parasitic nematodes is still dominated by chemical control, but in recent years, the application of chemical nematicides is wasteful, pollutes the environment, has poor selectivity, strong extinction, and damages soil biota. The 21st century is called the century of environmental protection, and the application of some effective chemical nematicides is gradually restricted, so the research on the biological control of plant parasitic nematodes has naturally become a hot issue
