Five key points for Prevention and Control of Edible Mushroom Diseases

First, prevention and control runs through cultivation all the time. In the whole process of cultivation, we should pay special attention to temperature and temperature control, strengthen ventilation, inhibit the growth and infection of pathogens, pay attention to the disinfection of appliances, and create a clean growth environment.

Second, focus on the treatment of culture materials and covering soil. The pathogens of various diseases of edible fungi mostly exist in culture materials and soil-covered materials, which is the initial infection source of edible mushroom diseases. therefore, in addition to fermentation material cultivation, especially in the disease area or old mushroom shed, clinker cultivation should be carried out as far as possible.

Third, pay close attention to the disinfection of places and environments. Many pathogens naturally exist on the soil surface, air and various organisms, especially the inner wall and bed frame of the old mushroom house, which will leave the pathogens left over from the previous production season. The simplest and most economical way to disinfect the environment and place is to expose yourself to the sun, which can lift the roof of the mushroom shed, bask in the ground first, then turn it deeply, and then expose it again. Formaldehyde, peracetic acid, sulfur and bleaching powder are also good environmental disinfectants with no pollution.

Fourth, early application of pesticides. Once the disease occurs in the mushroom stage, it should be treated as soon as possible, such as clearing the diseased mushroom, dealing with the focus, spraying fungicide and so on. If it is not dealt with in time, it is easy to cause the disease epidemic and difficult to control.

Fifth, first pick mushrooms and then apply medicine. In drug control, if the mushroom is not picked first, the fungicide is easy to pollute the mushroom body and cause a large number of residues. Therefore, in the process of chemical control, mushrooms must be picked first and then applied. After application, the mushroom room adopted dry management to inhibit the formation of fruiting body primordium. At present, the residual period of fungicides used is generally about 14 days, and the fruiting body of most edible fungi takes about 7 days from primordium formation to mature harvest.
