Management of coriander wilt using biocontrol agents

Abstract

Coriander is severely affected by the most common and wide spread wilt disease caused by Fusarium oxysporum f.sp. coriandri. Among the Bio-control agents, Trichodermma harzianum was found most effective to inhibit 83.69 per cent inhibition of mycelia growth of fungus in vitro and Seed treatment with Trichoderma harzianum at 4 g kg/seed was found to be more effective in reducing the wilt incidence to 20.81 per cent and 61.75 per cent disease control under field condition and maximum 801.33 kg/ha seed yield.
