Abstract:
Groundnut (Arachis hypogaea L.) is an economically important edible oil seed crop of the world. Collar rot disease incited by Aspergillus niger is the major constraints in groundnut crop in Rajasthan and almost all groundnut growing states. Field experiment was conducted to find out effective seed treatment fungicides and bioagents (Mancozeb, Carbendazim, Tebuconazole, Hexaconazole, Trichoderma, viride alone and soil application with T. viride and seed treated with tebuconazole) for control of collar rot of groundnut. All the treatments recorded significantly more seedling emergence (84.20 - 95.23%) in comparison to control (72.62%). The highest seedling emergence (95.29%) was recorded where soil application with T. viride and seeds treated with tebuconazole. Among fungicides and bioagents, minimum disease incidence (8.15%) and maximum pod yield (21.33 q/ha) was recorded by soil application with T. viride and seed treated with tebuconazole followed by seed treatment with tebuconazole disease incidence (10.53%) and pod yield (20.71 q/ha) in comparison to other treatments.
