Abstract/Contents:"Isolates of Pseudomonas aeruginosa from spent mushroom substrate were evaluated for efficacy and timing of application to control blast disease (gray leaf spot) of perennial ryegrass. Bacteria and the fungicides, azoxystrobin and propiconazole, were applied to 7-week-old plants at 1, 3, and 7 days prior to inoculation with Pyricularia grisea. Disease severity was assessed at 7 days after inoculation. Bacterial isolates provided a level of control that was comparable to that of propiconazole, but significantly lower than that of azoxystrobin. Timing of application was significant at all three intervals tested. Disease severity decreased with reduced time intervals between applications of P. aeruginosa and P. grisea. A comparison of disease severity for plants maintained in controlled-environment chambers and an outdoor setting showed no significant effects on the efficacy of P. aeruginosa. Further, the biocontrol activity of the bacterial isolates was not comprised by an exposure to UV radiation. This study indicates that P. aeruginosa may be employed in an integrated ryegrass blast disease management program."
