Groundnut regarded as “king of oil seed crops” is an economic important food legume and edible oilseed crop in India, which severely suffers from soil borne diseases of groundnut, collar rot (Aspergillus niger), stem rot (Sclerotium rolfsii) and root rot (Rhizoctonia solani) causing major havoc causes significant economic losses. The field experiments were conducted to find out the efficacy of Tebuconazole 6% FS as a seed treatment fungicide against collar rot, stem rot and root rot diseases complex in ground nut during Rabi 2014-15 and Rabi 2015-16. The treatment Tebuconazole 6% FS @ 4.0 ml/10 kg and Tebuconazole 6% FS @ 5.0 ml/10 kg of seeds were found be the best treatments for seed germination, root and shoot length in during both the seasons.During first season, Tebuconazole 6% FS @ 5.0 ml/10 kg of seeds and Tebuconazole 6% FS @ 4.0 ml/10 kg of seeds were recorded 1.77 and 2.14 per cent collar rot incidence, 3.07 and 4.23 per cent stem rot disease incidence and 4.93 and 5.05 per cent root rot disease incidence, respectively. Similarly during second season, Tebuconazole 6% FS @ 5.0 ml/10 kg of seeds and Tebuconazole 6% FS @ 4.0 ml/10 kg of seeds were recorded 1.89 and 2.06 per cent collar rot incidence, 4.05 and 5.13 per cent stem rot incidence and 5.74 and 5.94 per cent root rot incidence, respectively. The highest pod yield was obtained from seed treatment with Tebuconazole 6% FS @ 5.0 ml/10 kg of seeds i.e. 20.22 q/ha and 20.10 q/ha during first and second season, respectively and Tebuconazole 6% FS @ 4.0 ml/10 kg of seeds recorded 20.12 q/ha and 20.00 q/ha of pod yield during first and second season, respectively.
