Abstract

The invention discloses a strain of fluorescent pseudomonas (Pseudomonas protegens) XY2F4 and its application in preventing and treating crop verticillium wilt. The Pseudomonas fluorescens XY2F4 was deposited in the General Microorganism Center of China Committee for Microbial Culture Collection on June 24, 2019, with the preservation number CGMCC No.18017. The Pseudomonas fluorescens strain XY2F4 itself has no pathogenicity to plants, has a significant inhibitory effect on cotton verticillium wilt caused by Verticillium dahliae, can significantly reduce the occurrence of cotton verticillium wilt, and has Very good biological control effect. Genomic studies have shown that Pseudomonas protegens XY2F4 has a series of gene clusters for the synthesis of biological control-related compounds, which can be used to develop biopesticides for crop Verticillium wilt, providing new ideas and new ideas for the use of biological control of crop Verticillium wilt. method.

Description

technical field

[0001] The invention belongs to the technical field of plant disease biocontrol. More specifically, it relates to a strain of Pseudomonas protegens XY2F4 and its application in controlling crop verticillium wilt. Background technique

[0002] Cotton is an important economic crop in my country, providing renewable raw materials for the textile industry. Cotton verticillium wilt caused by Verticillium dahliae Kleb. is a devastating disease. The spread of the disease not only significantly reduces the cotton fiber quality, but also seriously affects the economic yield of cotton. Verticillium wilt caused by Verticillium dahliae causes direct economic losses in the billions of dollars worldwide each year. In 1982, cotton verticillium wilt had spread to nearly 130,000 hectares of agricultural soil in my country. By 1993, cotton verticillium wilt had become the main obstacle to high and stable cotton production in my country, and the affected area reached 2.666 m...
