Abstract

The present invention relates to a new biocontrol fungus and its application in the prevention and treatment of gray mold of crops; the biocontrol fungus CGMCC No.15763 of the present invention can effectively prevent and control gray mold of crops, and has a growth-promoting effect on crops; especially In terms of capsicum planting and application, it not only has a significant control effect on capsicum gray mold, but also can improve the drought resistance of capsicum and promote growth and increase yield; moreover, compared with the chemical agents of the prior art, the biocontrol bacterium of the present invention has It is non-toxic to humans and animals, does not pollute the environment, has no residue, and is conducive to the sustainable development of the ecological environment.

Description

technical field [0001] The invention relates to a biocontrol bacterium and its application in the control of gray mold of crops, and belongs to the technical field of crop biological control. Background technique [0002] Botrytis cinerea is a relatively serious disease in my country's agricultural production, especially causing serious harm to the cultivation and production of peppers. Pepper is one of the favorite vegetables. With the specialization of planting, due to the single variety, it is difficult to stubble. Years of continuous cropping cultivation has increased the base of Botrytis cinerea in the field year by year, which has led to the increasing occurrence of Botrytis cinerea. The general loss rate Up to 15% to 20%; in serious cases, up to 30% to 50%; up to 100%, causing a large number of leaves to rot and lose their edible value; at the same time, it can also cause field losses, and even cause serious damage during fruit storage and transportation. [0003] At...
