Oriental red fungus bacterial strain, Oriental red fungus bacterial agent and application thereof

Abstract

The invention provides a kind of oriental bacterium bacterial strain, described oriental bacterium bacterial strain is oriental bacterium I-1-1, is preserved in China Typical Culture Collection Center, preservation number is CCTCC NO:M2012368, compared with prior art, The production process of the Dongfanghong strain is simple and the cultivation time is short, and the strain can be used to prepare a biocontrol fungicide through a simple, fast, and low-cost operation method, which can effectively prevent and control rice bacterial blight, and is environmentally friendly and easy to apply. Convenience, low cost, no pollution, no phytotoxicity to crops, etc.

Description

technical field [0001] The invention relates to the technical field of biopesticides, in particular to the application of a novel microbial agent (Redrobium orientalis agent) in the prevention and control of rice bacterial blight. Background technique [0002] Bacterial blight, one of the main bacterial diseases of rice, is caused by the infection of Xanthomonas oryzaepv. oryzae and occurs in various rice areas in my country. After the leaves are infected by pathogenic bacteria, yellow-green spots appear on the tips and edges of the leaves, and then develop into pale, yellow-brown long stripes along the veins, and finally turn gray and die. Diseased plants are prone to lodging, and rice ears are not solid, which has a great impact on yield. Once the yield reduction occurs, it can reach 10%-20%, and when it is serious, it can reach 50%-60%, which seriously threatens the safe production of rice. [0003] At present, the control of rice bacterial blight mainly depends on the b...

AI Technical Summary

Problems solved by technology

The diseased plants are prone to lodging, and the ears of rice are not solid, which has a great impact on the yield. Once it occurs, the yield reduction can reach 10%-20%, and it can reach 50%-60% in serious cases, which seriously threatens the safe production of rice.

[0003] At present, the prevention and control of rice bacterial blight mainly depends on the breeding of resistant varieties and the application of chemical pesticides. The long-term use of a large number of chemical pesticides leads to problems such as pesticide residues, increased disease resistance, and environmental pollution, which seriously affects the sustainable development of agriculture.

However, resistance breeding is difficult and takes a long period, and the corresponding agricultural measures are complicated and economically invested.
