Integrated management of stem and pod rot of groundnut

Abstract

An integrated approach was followed for the management of groundnut stem and pod rot disease, caused by Sclerotium rolfsii under fi eld conditions using different biological agents, fungicides, oilcakes and organic manure as well as their combinations. Based on pooled analysis of two years performance of different treatments, two effective treatments were identifi ed for the management of stem and pod rot of groundnut. The treatment combination of deep ploughing + seed treatment with Trichoderma harzianum @ 4 g/kg of seed + furrow application of T. harzianum @ 4 kg enriched with 250 kg FYM/ha + neem cake @ 250 kg/ha was signifi cantly superior in recording least disease incidence of stem rot (9.9%) and pod rot (24.5%) and also recorded highest mean pod yield (13.64 q/ha), mean fodder yield (49.78 q/ha) and B:C ratio 3.03 followed by deep ploughing + seed treatment with T. harzianum @ 4g/kg of seed + furrow application of T. harzianum @ 4 kg enriched with 250 kg FYM/ha
which recorded mean stem rot incidence of 12.3% and pod rot incidence of 30.7% and mean pod yield 11.28q/ha, mean fodder yield of 42.81 q/ha and B:C ratio 2.18.
