How to prevent and cure edible fungus diseases? Wonderful measures for Prevention and Control of Edible Mushroom Diseases

Winter and spring is the golden period for the cultivation of edible fungus. during this period, diseases often occur due to the use of materials and environmental disinfection, which affect the yield and benefit of edible fungi. According to experience, it is very important to master the following skills.

Focus on the treatment of culture materials and soil cover

The pathogens of various diseases of edible fungi mostly exist in culture materials and soil-covered materials, so clinker cultivation should be carried out as far as possible in addition to fermentation materials, especially in disease areas and old mushroom sheds. In the cultivation practice of Pleurotus ostreatus, yellow spot disease is common in recent years, and has a serious development trend, but the clinker cultivation basically does not cause harm.

Pay close attention to the disinfection of places and environment

Many pathogens naturally exist on the soil surface, air and various organisms, especially on the inner wall and bed frame of the old mushroom house, there will be pathogens left over from the previous production season. Environment and place * * A simple and economical way is to expose yourself to the sun. You can lift the roof of the mushroom shed, bask the ground first, then turn it over deeply, and then expose it again. Formaldehyde, peracetic acid, sulfur and bleaching powder are also good environmental disinfectants with no pollution.

First pick mushrooms and then apply pesticide

When using 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 chemical control, mushroom must be picked first, then applied, and the mushroom house should be managed to inhibit the formation of fruiting body primordium. At present, the residual period of fungicides is generally about 14 days, and the fruiting body of most edible fungi takes about 7 days from primordium formation to mature harvest, so mushrooms can be picked only 8 days after application.
