1. Trichoderma: You should give up strains which have been jeopardized by Trichoderma. Currently, there are no ideal preventive drug on Trichoderma. Once Trichoderma is found, immediately ventilate and lower the humidity to control its extension. If compost is affected by Trichoderma during the spawn running period, inject one solution to inhibit its extension. Common solutions are 5% Carbolic Acid Solution, 2% Formaldehyde Solution and lime water with the PH Value of 10. Spraying quick lime facilitates reaching good prevention effect.  
2. Neurospors Crassa: it presents villiform, white or gray in early growth stage. The growth of Neurospors Crassa is slow and can reduce the pollution when the temperature is controlled under 20 degrees during spawn-running period. At the same time, controlling the humidity is conductive to effectively prevent the occurrence of Neurospors Crassa. When finding that fungi sacks are influenced by Neurospors Crassa in the late period of spawn running, immediately bury them in 30-40 cm depth of soil with poor permeability. After 10-20 days of anaerobic treatment, the harm of Neurospors Crassa could be effectively reduced. The prevention measure is as same as the one with Trichoderma.
3. Mucor: it is also called Black Mucor, presents white or black in the late growth stage and holds higher incidence in the condition of high temperature, high humidity and poor ventilation. The prevention measure is as same as the one with Trichoderma.
