近来,在福建闽东菇区发现一种香菇的新病害——香菇菌筒线虫病。据在发病较重的屏南县调查,发病面积达30％～40％,菌筒发病率在40％以上,病筒损失率在74％～80％。因此,香菇菌筒线虫病是一种对香菇生产具有潜在威胁的一种重要病害。为了给病害防治提供科学依据,我们于1993年对该病病原、病害的发生规律、危害性进行了初步观察,现将结果记述如下:
Recently, a new disease of mushrooms was discovered in mushroom zone in Fujian Province - Lentinus edodes. According to the survey in Pingnan County, where the incidence is heavier, the incidence area is up to 30% -40%, the incidence of bacteria tube is above 40%, and the loss rate of pathological tube is between 74% and 80%. As such, Lentinus edodes is an important disease that poses a potential threat to mushroom production. In order to provide a scientific basis for the prevention and treatment of diseases, we carried out preliminary observations on the pathogen and disease occurrence and the harmfulness of the disease in 1993. The results are as follows:
