symptom During the growth and development stage of the fruit body, the base of the stipe was dark brown and black eroded, and after the basal erosion, the fruit body was lodging. Mushroom clusters, although not the incidence of lodging, but can not continue upward growth and development, severe occurrence, needle-like young mushrooms into a black cluster erosion. pathogen Penicillium bottlenecks, belonging to the semi-known fungi, subsporidia, filariae, plexiformes, and plexiformis. The pathogens are white and powdery on potato sucrose medium. The medium was dark red brown and the colonies were pink. The sprigs grow from aerial hyphae and are symmetrically bifurcated.

Occurred in cottonseed husk raw material cultivation of the mushroom bed, the growth phase of the culture material moisture is too high, the bed surface for a long time with water, combined with long time covered the film, poor ventilation, wet fertility is too large, favorable to happen. Prevention 1. The appropriate water content is controlled during the growth stage of the fruit body, and it is often important to eliminate the water in the bed area, and it is particularly important to eliminate the accumulated water during the growth stage of the fruit. 2, after the discovery of mushrooms should be promptly eliminated, and then spray 1:500 times 25% carbendazim or 65% of dexamethasone, can receive a certain control effect.
