Occurrence and Identification of Bacterial Brown Patch of Processing Mushrooms in Northern Xinjiang
[Objective] Brown blotch disease often makes edible fungi affected in Northern Xinjiang, which makes the commercial quality drop sharply in the cultivated Pleurotus ferulae and in the oyster mushroom (Pleurotus ostreatus). The infested cultivated Pleurotus ferulae and oyster mushroom (Pleurotus ostreatus) were observed in succession in Habahe Country and Banfanggou Township of Xinjiang during June, April and June in 2011. The purpose of this study was to determine the pathogens, which might make contribution to controlling the disease. [ Method ] Pathogenicity of isolates were measured by using pitting test inoculating. The strains were identified based on morphological, cultural and physiological; then antibacterial toxicity test in room was done. [Result] We can screen strains with pitting test inoculating button mushroom (Agaricus bisporus). They have pathogenicitian differences and their morphology and characteristics are of ivory colony, round, flatted, smooth surface, shining luster, smooth margin and show significant fluorescence reaction. [ Conclusion] The pathogenicity of brown blotch disease is Pseudomonas tolaasii. The antibacterial toxicity test result is 20% Bismerthiazol bactericide WP < 20% thiodiazole- copper SC<72% agricultural streptomycin, but new bactericide is the better choice.
