在盆栽条件下,9个木霉菌株对棉花丝核菌立枯病的防治效果为39.71%-82.35%,14个菌株对棉花枯萎病的防治效果为37.5%-75.00%,9个菌株对棉花黄萎病的防治效果为30.49%-65.85%。制备了绿色木霉LTR2的可湿性粉剂,田间条件下处理种子及灌根,菌剂对棉花枯萎病的防治效果达50.1%-80.0%。
Under the condition of pot culture, the control efficacy of 9 Trichoderma strains on Rhizoctonia solani was 39.71% -82.35%, and that of 14 strains was 37.5% -75.00% on Fusarium wilt. Verticillium wilt control effect of 30.49% -65.85%. The wettable powder of Trichoderma viride LTR2 was prepared, and the seed and irrigation root were treated under the field conditions. The control effect of the fungicide against cotton blight was 50.1% -80.0%.
