12 results about "Rhizoctonia solani" patented technology

Rhizoctonia solani (teleomorph: Thanatephorus cucumeris) is a plant pathogenic fungus with a wide host range and worldwide distribution. It was discovered more than 100 years ago. R. solani frequently exists as thread-like growth on plants or in culture, and is considered a soil-borne pathogen. R. solani is best known to cause various plant diseases such as collar rot, root rot, damping off, and wire stem. R. solani attacks its hosts when they are in their early stages of development, such as seeds and seedlings, which are typically found in the soil. The pathogen is known to cause serious plant losses by attacking primarily the roots and lower stems of plants. Although it has a wide range of hosts, its main targets are herbaceous plants. R. solani would be considered a basidiomycete fungus if the teleomorph stage were more abundant. The pathogen is not currently known to produce any asexual spores (conidia), though it is considered to have an asexual lifecycle. Occasionally, sexual spores (basidiospores) are produced on infected plants. The disease cycle of R. solani is important in management and control of the pathogen.

This invention provides a strain of *Pseudomonas aeruginosa* RL76, its bacterial suspension, its preparation method, and its applications, belonging to the field of agricultural microbiology technology. The *Pseudomonas aeruginosa* RL76 was deposited at the China General Microbiological Culture Collection Center (CGMCC) on January 26, 2026, with accession number CGMCC No. 37531. This invention utilizes a mixture of filter mud and soil for sugar beet cultivation. It was found that, under the same pathogen inoculation conditions, the filter mud treatment significantly alleviated the occurrence of damping-off disease in sugar beets compared to the non-filter mud treatment, suggesting that the filter mud plays a role in increasing the relative abundance of beneficial microorganisms in the soil. Therefore, this invention isolated a strain of *Pseudomonas aeruginosa* RL76 with highly efficient antagonistic activity against *Rhizoctonia solani* from the rhizosphere soil of sugar beets cultivated using a mixture of filter mud and soil, and for the first time discovered its effective control of sugar beet damping-off disease while also promoting sugar beet growth, representing a groundbreaking achievement.
