The present invention provides a strain of Rhodothrothia thiarophilum, said strain of Rhodothrothia thiaphila IV-1, preserved in China Center for Typical Culture Collection, and the preservation number is CCTCC NO: M2012369, Compared with the prior art, the present invention has the following beneficial effects: low production cost, fast growth rate, high efficiency, non-toxicity, and environmental protection, and the bacterial agent can be prepared by a simple and fast operation method, which can be obtained by using the bacterial strain of the present invention The bacterial agent is convenient to use, has good control effect on rice sheath blight, and can effectively guarantee the safe production of rice.

Description

technical field [0001] The invention relates to the technical field of biopesticides, in particular to the application of a thiarophilic oomycete in preventing and controlling sheath blight. Background technique [0002] Rice sheath blight is one of the three major diseases of rice, caused by Rhizoctonia solani (Rhzioeotniasoalni). The disease can occur throughout the rice growth period, and mainly damages the leaf sheaths and leaves. It is highly harmful, highly prevalent, and has a wide range of hosts. [0003] Due to the strong saprophytic ability and wide range of hosts of sheath blight, no high resistance varieties to the disease have been found at home and abroad. Jinggangmycin, the main control agent for this disease, has produced obvious drug resistance, and the number of times of application per season has increased from 2 times 20 years ago to 3-5 times now. The use of chemical agents has caused major problems such as environmental pollution and agricultural prod...
