Abstract

The invention relates to an application of pseudomonas chlororaphis subsp.aureofaciens in preventing and controlling nematode. The pseudomonas chlororaphis subsp.aureofaciens is chlororaphis subsp.aureofaciens GDMCC NO. 60273. The invention relates to the application of pseudomonas chlororaphis subsp.aureofaciens in preparing a biological bacteriostatic agent for preventing and controlling nematode. The biological bacteriostatic agent includes the chlororaphis subsp.aureofaciens served as an active ingredient and a carrier. The biological bacteriostatic agent is chlororaphis subsp.aureofaciensfermentation liquor. A method for preventing and controlling nematode comprises the step of spraying the biological bacteriostatic agent containing chlororaphis subsp.aureofaciens in claim 1 and / or fermentation liquor thereof onto an affected part. According to the application of pseudomonas chlororaphis subsp.aureofaciens in preventing and controlling nematode provided by the invention, chlororaphis subsp.aureofaciens used for preventing and controlling nematode is free from pesticide residue, free from environmental pollution and safe to human and livestock. Application of pseudomonas chlororaphis subsp.aureofaciens in preparing the biological bacteriostatic agent for preventing and controlling nematode is characterized by simple preparation process, low cost, excellent effect and convenience in use.

Description

technical field [0001] The invention relates to biological control and biological bacteria agent, in particular to the application of Pseudomonas chloropinus in the control of nematodes. Background technique [0002] Phytopathogenic pests harm forests, food, vegetables, fruits and other plants. They have a wide range of hosts, strong concealment, and difficulty in prevention and control. They have become key diseases that threaten agriculture and forestry, and have caused great harm to national economic production. influences. The global control of plant and crop pests and diseases is still dominated by chemical control. Although chemical control measures have high insecticidal efficiency, they have defects such as high toxicity, easy residue, and environmental pollution. With my country's emphasis on green agriculture, research and development of green, safe and environmentally friendly pathogenic nematode control technologies is an inevitable measure to promote economic-e...
