Evaluation of Bio-control agents against Root rot disease of French bean caused by Rhizoctonia solani under field condition

Abstract

Seed treatment with Trichoderma viride @ 5.0 g/kg seed showed maximum seed germination (85.82%) and minimum pre- emergence (13.93%) and post- emergence (17.00%) root rot incidence and The maximum yield (63.44 q/ha) was also recorded by seed treatment with T. veride @ 5.0 g/10-6 spores/ml followed by Aspergillus niger @ 5.0 g/10-6 spores/ml (62.33 q/ha). Correlation coefficient studies exhibited negative and highly significant association of pre- and post-emergence root rot disease incidence with green pod yield during both the years Rabi 2014-15 and 2015-16 cropping seasons.
