Management of Sclerotinia rot of mustard following biorationals approaches
Abstract
Sclerotinia rot caused by Sclerotinia sclerotiorum (Lib.) de Bary has become a significant agricultural problem in Indian mustard.The existing control measures are also the application of chemical fungicide which are often cost prohibitive, impractical and hazardous to environment and human health. Keeping this in view, the need was felt for an alternative method to manage this disease in eco-friendly manner following biorational approach.Sclerotinia rot of Indian mustard can be effectively managed by seed treatment (@ 10g/kg), soil application (@2.5 kg/ha) and two foliar sprays (@0.2%) at 50 and 70 DAS with talc based formulation (2x 106 cfu/g) of T. harzianum. This management practice will reduce the excessive use of chemical pesticides and ultimately save the expenditure
