Prevention of soft rot of edible fungi

Last Updated: 2024/11/22, Symptoms: When the disease occurs, white hyphae appear on the mushroom bed and spread rapidly. If it is not controlled in time, it can be extended to the whole mushroom bed. In the case of higher humidity, all the fruiting bodies can be "swallowed" and only a mass of white hyphae can be seen. In the later stage, the white hyphae become water red. 2. Occurrence characteristics: soft rot bacteria widely exist in soil, form colonies on the surface of soil or mushroom body, and produce spores in a short period of time. These spores spread by means of air flow, water droplets splashed when spraying water and exudation of mushroom body. Overwet and cold soil cover

2. Occurrence characteristics: soft rot bacteria widely exist in soil, form colonies on the surface of soil or mushroom body, and produce spores in a short period of time. These spores spread by means of air flow, water droplets splashed when spraying water and exudation of mushroom body. This disease is easy to occur under the condition of overwet soil and low temperature. This disease often occurs in small areas in mushroom houses and rarely prevails in large areas.

III. Control methods:

1. Cover soil for disinfection.

2. When the disease occurs locally, the number of spraying water on the mushroom bed should be reduced, the ventilation of the mushroom house should be strengthened, and the humidity should be reduced. Spray 2%~ 5% formaldehyde solution or 500 times thiophanate-methyl solution on the affected parts for control, or sprinkle quicklime powder for control.
