Two isolates of Trichoderma koningii were evaluated for efficacy in control of damping-off diseases in seedlings of Capsicum annuum grown in pasteurized potting medium in a glasshouse. A selected isolate of binucleate Rhizoctonia and two fungicides were also included as standards for control of Rhizoctonia solani and Pythium ultimum var. sporangiiferum. Both isolates of T. koningii reduced seedling death caused by R. solani in one of two experiments, and by P. u. sporangii-ferum in two of three experiments. Neither isolate of T. koningii suppressed damping-off caused by either pathogen as consistently as the binucleate Rhizoctonia or fungicides. The implications of these results for commercial disease management are discussed.
对两株康氏木霉分离株在温室中经巴氏消毒的盆栽基质中生长的辣椒幼苗猝倒病防治效果进行了评估。还选用了一株双核丝核菌分离株和两种杀菌剂作为防治立枯丝核菌和终极腐霉变种孢囊腐霉的对照标准。在两项实验中的一项中，两株康氏木霉分离株均降低了由立枯丝核菌引起的幼苗死亡率，在三项实验中的两项中降低了由终极腐霉变种孢囊腐霉引起的幼苗死亡率。两株康氏木霉分离株对两种病原菌引起的猝倒病的抑制效果均不如双核丝核菌或杀菌剂稳定。讨论了这些结果对商业病害管理的意义。
