Abstract
Efficacy of three strains of Pseudomonas aeruginosa multiplied on wheat bran, rice husk and saw dust evaluated in the control of soil-borne root infecting fungi under screen house and field conditions. Wheat was found as a good substrate for mass multiplication of the bacterium as compared to saw dust and rice husk, Wheat bran inoculum of P. aeruginosa strains significantly (p < 0.05) controlled infection of Macrophomina phaseolina, Fusarium solani and Rhizoctonia solani on cotton under green house and also on sunflower, soybean, uridbean and cotton under field conditions with enhancement in plant growth. Bacterial antagonists showed better biocontrol and growth promoting effects in the screen house as compared to their use in the field.
