Abstract

Sesame (Sesamum indicum L.) is an important oilseed crop cultivated in various parts of the world. Alternaria sesami is a devastating fungal pathogen that causes significant yield losses in sesame crops worldwide. The survey conducted revealed a maximum disease incidence of 55.00 percent at Namakkal. Alternaria sesami was isolated from the leaf blight-infected sesame leaves. Trichoderma viride recorded significant results against Alternaria sesami in vitro. T1R2 showed the highest percent inhibition over control (PIOC) (77.77%) on mycelial growth of Alternaria sesami. 72.22 and 67.77 percentages of inhibition were recorded in T1R1 and T1R3, respectively.
