Brown blotch disease is a bacterial infection that affects nearly every specie of mushroom. The infecting bacteria, Pseudomonas tolaasii, produces the toxin tolaasin that causes brown spots to cover the surface of the mushroom. Brown blotch disease is especially problematic on common mushroom farms, where it can spread quickly and cause huge economic losses.

High throughput isolation method of fungi
The invention belongs to the field of biotechnology, and provides an isolation method for highly parasitic pathogenic fungi, for study in the future. Single spore isolation is an effective method for isolating the highly parasitic pathogenic fungi, and is particularly suitable for isolating the pathogenic fungi that suffer severe pollution caused by isolation with a conventional method and are difficult to isolate successfully, namely, venturia nashicola, marssonina mali and cercospora chionea. A conventional single spore isolation technology is complex in operation and high in technical requirements, thereby restricting applications thereof. In the isolation method provided by the invention, by punching holes with capillary tubes having the diameter of 1 mm, an operation process is greatly simplified; operability of single spore isolation is stronger; and speed is faster. A general technical staff can master the technology through simple training, thereby broadening an application scope of the method.
