Rhodobiumorientis strain, rhodobiumorientis fungicide and application of rhodobiumorientis strain and rhodobiumorientis fungicide

Abstract

The invention provides a rhodobiumorientis strain. The rhodobiumorientis strain is rhodobiumorientis I-1-1 and is preserved in the China Center for Type Culture Collection, and the preservation numberis CCTCC NO:M2012368. Compared with the prior art, the rhodobiumorientis strain is simple in production process and short in culture time, the antibiological inoculant can be prepared from the strainthrough a simple, rapid and low-cost preparation method, rice bacterial leaf blight can be effectively prevented and treated, and the advantages that environmental friendliness is achieved, application is easy and convenient, the cost is low, pollution is avoided, and no spray burn is caused to crops are achieved.

Description

technical field [0001] The invention relates to the technical field of biopesticides, in particular to the application of a novel microbial inoculum (Rhodobacterium orientalis inoculum) 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 depen...

AI Technical Summary

Problems solved by technology

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