The optimal methods on preventing mushroom diseases and pests

2017-02-16 16:25:50

Disease and pests are fatal as long as they appear during mushroom cultivation, therefore, you could prevent them in advance, the followings are four optimal methods:
1. Cut off route of transmission:
A. Strains usually carry pests and source of the disease.
B. Compost and earthing carry pests and sources of the disease.
C. The natural spreading in inside and outside of mushroom house. Cutting the three mentioned sources is the priority among priorities.
2. Environmental control:
A. Lower the temperature of the material: When the temperature of material in spawn running is controlled under 21 degrees, it will be effective to prevent Diehliomycesmicropours. The pollution on fungus sacks could be controlled when the temperature of spawn running on Enoki mushroom is controlled under 20 degrees and when the temperature of fungus sacks on Oyster mushroom is controlled under 20 degrees.
B. Enhance the ventilation: Ventilation is the best air disinfection method, hence be sure not to create clammy fruiting environment.
C. The regulation of illumination: The requirements on illumination vary from variety to variety. Button mushroom requires partial dark illumination while Pleurotus nebrodensis needs partial hard light.
3. Agronomic measures: Different soil holds different microfloras while different ecological environment possesses different biocoenosis. Practice has proven that in the cultivation of solar greenhouse, the first year is better than the second year on cultivation situation, the main reason is that the ecological environment of solar greenhouse will become worse ans worse as the increasing diseases and pests and bad air quality. Therefore, you should improve the ecological conditions and optimize the fruiting environment and lower the occurrence rate of diseases and pests.
4. Chemical control: Chemical control is mainly used during the prevention measures, during the fruiting period, it is improper to use drugs as the organization structure of sporocarps are easy to leave drug residues and affect export and edible quality. Therefore, you could spray drugs before fruiting as a last resort and it is best to spray galenica or matrine.
