Young mushroom primordia may die for several reasons, reducing yield and quality. Examine the following factors to identify the problem and act promptly.
1. Poor varietal tolerance: some strains cannot adapt to fruiting-stage temperature changes. A day–night difference above 10°C may stop growth and cause mushrooms to shrink and die.
2. Diseases in the casing layer can infect young primordia, while mites and nematodes may consume nutrients and cause shriveling or death. Inspect symptoms to identify the pest or disease and choose an appropriate mushroom treatment.
3. Chemical injury: some organophosphorus pesticides inhibit or kill mycelium and mushrooms. The source cites dichlorvos-related mortality and deformity, and carbendazim-related wood ear deformity. Do not apply treatments indiscriminately; use approved products and follow authorized rates and methods.
4. Mechanical damage: densely clustered mushrooms may suffer damage to young mushroom bases during harvest, causing them to die.
5. Excessively dry, wet or hot conditions can all cause young mushrooms to die.
