Two fungicides (carboxin and thiram) and two bio-control agents (Pseudomonas fluorescens and Trichoderma harzianum) were evaluated as seed treatment in different combinations against Sclerotium rolfsii, the causal organism of collar rot of chickpea (Cicer arietinum). Seed treated with T. harzianum (4g/kg seed) + carboxin (0.5g/kg seed) provided maximum protection to the crop by giving maximum seedling emergence (495.0/20 m2), final plant stand (480.4/20m2) and grain yield (18.2q/ha). Other treatment combinations significantly increased seedling emergence, final plant stand and grain yield compared to control.
