Abstract

Banded leaf and sheath blight disease of maize is incited by Rhizoctonia solani f. sp sasakii (RSS) and it can be effectively managed by biointensive management package, such as use of biofumigation of soil with mustard plant material in combination with potential P. fluorescens and Trichoderma harzianum for enhanced yields. The viability of RSS inoculum decreased in all the biofumigation treatments as compared to untreated control. The decrease in the viability ranged from 81.7 to 99%. Maximum reduction in the viability was recorded in treatment biofumigation + seed treatment + soil drenching + foliar spray with P. fluorescens. The radial growth of the inoculum in different treatments showed significant differences when compared to control which ranged from 44.7 to 90 mm. Total bacteria, Trichoderma spp. and Pseudomonas spp. population were high in all bio-fumigant treatments 50 days after incorporation of mustard plant material in both green house and field studies.
