Isolates of Pseudomonas spp. collected from the rhizosphere of sugarcane and cane stalks were screened for their antagonistic activity against Colletotrichum falcatum causing red rot disease in sugarcane. Talc formulations of the selected Pseudomonas spp. isolates improved the sugarcane vegetative sett germination and sugarcane growth under field conditions. Optimal talc formulations were assessed for their effect on induction of systemic resistance against the pathogen in the canes under artificial inoculation. All the four isolates CHAO, EP1, KKM1 and VPT4 were effective in inducing systemic resistance against C. falcatum in two seasons. In other studies, the bacterial formulations were assessed to induce resistance in sugarcane in a sick plot situation. In pathogen-infested soil the isolates KKM1 and CHAO suppressed the red rot disease development in susceptible sugarcane cultivar. Pseudomonas strains also protected sugarcane in a disease-endemic location. Pseudomonas spp treatment substantially improved the cane juice quality parameters affected by the pathogen infection. Standardization of talc formulations and application methods in the field offers potential for large-scale application of biocontrol formulations for the management of red rot disease in sugarcane growing regions Not Available |
