After it is found that there is straw mushroom infection, it is necessary to reduce the temperature of the mushroom room in time and maintain ventilation, which can effectively control Trichoderma. If you are infected with Trichoderma at the time of infection, you can take the method of injecting liquid to inhibit the expansion of Trichoderma. The commonly used agents are 5% carbendazim, 2% formaldehyde, 50% carbendazim, 100% thiophanate methyl, etc., or spread a layer of lime to control its spread.
