Abstract

An experiment was conducted to assess the efficacy of a Trichoderma harzianum formulation on the wilt disease of cumin caused by Fusarium oxysporum f, sp. cumini and crop yield. The results showed that in Trichoderma seed treatment plots, percent wilt disease was 9.2 to 23.8 and 8.5 to 21.4 compared to 68.3 and 69.67 in control during first and second years of experiment, respectively. In Trichoderma treatment the yield recorded was 6.17 to 6.73 and 6.33 to 6.89 q/ha compared to 4.39 and 4.73 q/ha in untreated control during first and second years of experiment, respectively. The application also did not lead to any phytotoxic symptoms on the host plants.
