NOVELTY - A Trichoderma viride strain ZBS6 deposited under CGMCC No.3538, is new.    USE - The Trichoderma viride strain ZBS6 is useful in prevention of wheat banded sclerotial blight, wheat Gaeumannomyces graminis var tritici, apple tan disease, hot pepper Fusarium oxysporum, cucumber Botrytis cinerea, and wheat powdery mildew (all claimed).    ADVANTAGE - The Trichoderma viride strain ZBS6 is toxic-free, simple in use, environment-friendly, and strong in inhibitory effect.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are: (1) a liquid or solid antimicrobial prepared by using Trichoderma viride strain; and (2) a method for preparing the liquid bio-control antimicrobial, comprising: (a) carrying out preparation of liquid fungicide: transferring stored T. viride ZBS6 on the potato dextrose agar (PDA) culture base flat plate; alternately culturing for 4 days at 26 degrees C in bright and dark environment; scraping meristematic robes with asepsis condition; using asepsis water to configure to 1x 107 meristematic robe suspension liquid; inoculating according to 1 ml robe suspension liquid/100 ml PDA culture base; placing at 26 degrees C and at speed of 150 rotations/minute condition for vibrating culturing for 3 days; where the electronic stirring machine stirs for 2 minutes at speed of 2000 rotations/minute; mixing with 1.9 L phosphoric acid buffering liquid comprising 0.1% assistant Tween 100 and 0.2% preservative benzoic acid to obtain the liquid bio-control antimicrobial; and (b) carrying out preparation of solid fungicide: transferring stored T. viride ZBS6 on the PDA culture base flat plate; alternately culturing for 4 days at 26 degrees C in bright and dark environment; scraping meristematic robes with asepsis condition; using asepsis water to configure to 1x 107 meristematic robe suspension liquid; inoculating according to 2 ml robe suspension liquid/100 g substrate culture base; placing at 26 degrees C and alternately culturing for 8-10 days; and mixing to be even to obtain solid bio-control antimicrobial.
