Abstract

The invention discloses a microbial agent for controlling crop diseases and insect pests and a bacterial fertilizer thereof. The microbial agent comprises Bacillus subtilis, Paenibacillus kribbensis, Bacillus licheniformis and Acremonium strictum at a living bacteria count ratio of (1-60):(1-60):(1-60):(1-60), wherein the living bacteria count of the microbial agent is more than 1*10<10> / ml. The bacterial fertilizer comprises the microbial agent, a fertilizer and a carrier. Through combination of the microbial agent and the fertilizer, the microbial agent of the invention can archive the effect of controlling cucumber root-knot nematode disease and blight and can promote the nutrition supply for plant growth.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a microbial bacterial agent and bacterial fertilizer which can be used for preventing and controlling crop diseases and insect pests. Background technique [0002] As a soil-borne disease, cucumber wilt is one of the main diseases in cucumber production all over the world. The disease is caused by Fusarium oxysporum Cucumber specific. Continuous cropping for three years will cause the incidence of cucumber wilt to reach 70%, and the yield will decrease by 60%-100%, causing significant losses. At present, the prevention and control of soil-borne cucumber wilt mainly include physical and chemical control methods. The former is time-consuming and laborious, and it is difficult to carry out large-scale promotion in production, while the latter is harmful to the environment and human body. The biological control of soil-borne Fusarium wilt has attracted more and more attention....
