Trichoderma longibrachiatum and application thereof

Abstract

The invention discloses trichoderma longibrachiatum and application thereof, and belongs to the field of biological control of plant diseases. The trichoderma longibrachiatum is preserved in the China General Microbiological Culture Collection Center (CGMCC) on March 25, 2021, and the preservation number is CGMCC NO.21474. The trichoderma longibrachiatum T23 strain is obtained in the separation process of rhizoctonia solani, is parasitized on a rhizoctonia solani colony, has the characteristics of fast growth, more spores and the like, and is suitable for large-scale production. Trichoderma longibrachiatum T23 aerial hyphae are not developed, bacterial colonies are white at the beginning, the bacterial colonies become green at the later stage along with growth of the hyphae, and the trichoderma longibrachiatum and rhizoctonia solani are cultured oppositely, so that the growth of the bacterial colonies of the rhizoctonia solani can be inhibited, the bacterial colonies of the rhizoctonia solani can be completely covered at the later stage, and the rhizoctonia solani can be parasitized in a winding manner. The strain has a good application prospect in the green disease prevention and control direction of millets.

Description

Technical field [0001] The invention belongs to the field of plant disease biological control, and in particular, the present invention relates to a long branched wood mold and its application thereof. Background technique [0002] Valley originated in my country, its planting area and production accounted for more than 80% of the world. Xiaomi is rich in nutrients, which is increasingly favored in the world's small grains. Valley drought resistance, is a high-quality drought-drought crop in the arid area in northern my country, plus grain is the high-quality forage of cattle and sheep. In the case of cultivated land, it is the first choice for the development of livestock farming industry. It can be seen that Valley has shown increasing strength in the current planting structure adjustment, and the development prospect is unlimited. There are a variety of diseases in different parts of the valley, and the main disease of the leaves is a variety of crute, grain, and millet bendel...

AI Technical Summary

Problems solved by technology

After the onset, it will pollute the millet and affect its variety and safety

There are many physiological races in many diseases of millet, such as cereal blast and rust, which are prone to variation in physiological races, resulting in the loss of disease resistance of millet, and the varieties bred in production have a lack of resistant varieties

The spraying of chemical pesticides on millet is likely to cause environmental pollution and pesticide residues, which is not conducive to the green production of millet

For a long time, the prevention and treatment of millet diseases has mainly relied on frequent spraying of pesticides, which is not only time-consuming and labor-intensive, but also pollutes the environment, causes pesticide residues and produces drug resistance, which does not meet the trend of people's demand for green food
