The collor rot incidence in groundnut was reduced by the application of Trichoderma viride as seed treatment along with fungicides. In vitro studies of fungal and bacterial antagonists, viz., Trichoderma spp. and Pseudomonas fluorescens indicated that T. viride was more effective in inhibiting the pathogen A. niger. In pot culture experiment, the combined effect of seed treatment with T. viride and captan resulted in significant reduction of collor rot. Combination of antagonist and fungicide also improved the growth parameters like length of the plant, biomass and yield besides decreasing the disease incidence. Biointensive disease management of collar rot is not only effective but also economical.

In vitro studies of fungal and bacterial antagonists, viz., Trichoderma spp. and Pseudomonas fluorescens indicated that T. viride was more effective in inhibiting the pathogen A. niger. In pot culture experiment, the combined effect of seed treatment with T. viride and captan resulted in significant reduction of collor rot. Combination of antagonist and fungicide also improved the growth parameters like length of the plant, biomass and yield besides decreasing the disease incidence. Biointensive disease management of collar rot is not only effective but also economical.
