Abstract: Crossandra infundibuliformis var. Danica is a very valuable ornamental flowering potted plant that has been introduced to the international floriculture market. A wilt caused by Fusarium oxysporum is a major problem in the production of C. infundibuliformis plants. Control of F. oxysporum causing wilt disease of C. infundibuliformis var. Danica was investigated using Trichoderma isolates. The isolates effected the growth of Fusarium in laboratory experiments. The results suggest that the effect on fungicidal. The Trichoderma isolates also effectively reduced the wilt incidence in field experiments. Further, the isolation promoted the growth of the plants. The study strongly suggests that Trichoderma isolates, especially T. viride Tv1 can be exploited for the biological control of wilt disease at field level.
