Harnessing microbial consortia for induced systemic resistance and sustainable management of dry root rot in cluster bean under hot arid climatic conditions.

ABSTRACT: Dry root rot, caused by Macrophomina phaseolina, severely threatens cluster bean production, necessitating sustainable management strategies. This study aimed to screen, characterize and evaluate microbial isolates with antagonistic potential against M. phaseolina. Among 763 isolates, Trichoderma breve 37F, Pseudomonas sp. 8B, Aneurinibacillus aneurinilyticus 16B, and Bacillus velezensis 32B exhibited strong biocontrol and plant growth-promoting traits. All four biocontrol agents demonstrated good compatibility. Pot experiments revealed that the four-microbe consortium comprising T. breve 37F + Pseudomonas sp. 8B + A. aneurinilyticus 16B + B. velezensis 32B significantly suppressed M. phaseolina, achieving 87.13%
