由有害疣孢霉（Mycogone perniciosa）引起的双孢蘑菇褐腐病是八十年代末开始在上海蔓延的重要真菌病害,菇房一旦发病,产量大幅度下降,其初侵染源是蘑菇覆上,掌握适宜的栽培季节,避免过早播种和覆土;7～8月份曝晒覆土;覆土前一周用化学纯36％～38％甲醛熏土;结合蘑菇调水,施用混灭剂、特克多、多丰农、施保功、多菌灵以及甲基托布津等化学药剂,能有效控制病害;及时摘除病菇,防止孢子飞散,避免或减少蘑菇被再次侵染及采用抗病品种,能防止病害发生。
Agaricus bisporus brown rot caused by Mycogon perniciosa is an important fungal disease that started to spread in Shanghai in the late 1980s. Once the mushroom house is affected, its yield will drop sharply. The primary source of infection is the mushroom coating , To grasp the appropriate planting season, to avoid premature sowing and soil cover; 7-8 months of exposure to cover soil; chemical soil pure 36% to 38% of formaldehyde soil smoked soil the week before the soil cover; combined with mushroom water, the use of defoamers, Duofengnong, Shi Bao Gong, carbendazim and thiophanate-methyl and other chemical agents, can effectively control the disease; timely removal of mushrooms to prevent the spores fly to avoid or reduce the mushrooms were re-infected and the use of resistant varieties, to prevent diseases .
