Abstract

Cowpea [Vigna unguiculata (L.) Walp.] is an important legume that suffers from several diseases caused by Macrophomina phaseolina (Tassi.) Goid from seedlings until harvest. The present study involved the biological management of Macrophomina diseases by six pesticide-tolerant non-pathogenic isolates of rhizobacteria, including species of Bacillus and Pseudomonas. All isolates were tolerant to methomyl, imidacloprid, or carbendazim at different concentrations. Antibiosis, competition, the production of volatile and non-volatile compounds, cell wall-degrading enzymes, siderophores, growth hormones, and phosphate solubilisation were attributed to the biocontrol and growth promotion mechanisms of all the selected rhizobacteria. The disease severity index (DSI) and plant health index (HI) were calculated after applying bioagents under controlled conditions in pot and field trials for three consecutive years. A t-test was performed on the DSI data for the different treatment groups and time periods. A formula has been devised correlating changes in DSI with time in different culture conditions, revealed a progressive increase in DSI in treatments without bacteria, hydropriming, or pathogens. Treatment with Bacillus cereus, Pseudomonas donghuensis, and Pseudomonas aeruginosa showed lower DSI compared to the other treatments. The HI of Vigna plants was found to be maximal after treatment with P. aeruginosa. The link between DSI and HI was inversely proportional, and a highly significant correlation was found at p
