Induced systemic resistance (ISR) in blackgram using organic amendments and biocontrol agents against Macrophomina phaseolina was studied under pot culture conditions. Soil application of FYM 12t ha-1 combined with seed treatment (4g kg-1) and soil application (5kg ha-1 on 30 DAS) of T. viride significantly increased defense related proteins, viz., peroxidase (14.34 units min-1 g-1) and polyphenoloxidase (3.96 units min-1 g-1) activities as a sign of systemic resistance coupled with reduction in ischolar_main rot incidence from 99.6 to 13.8 per cent and also increased the yield and yield attributes of blackgram.
