Abstract/Contents: | "Intense use of fungicides on golf courses has raised concerns about envrionmental pollution, effects on nontarget organisms including humans, and development of resistant pathogen populations. Systems utilizing the highly rhizosphere competent biocontrol fungus Trichoderma harzianum strain 1295-22 are being developed for biological and integrated biological/chemical control of soil and foliar pathogens. In field trials, this strain was sprayed in the presence of a surfactant or as a component of an integrated system containing either iprodione or triadimefon at 0.5x the label rate. The biologicals always gave significant disease control but not always at commercially acceptable levels. In general, however, the integrated treatments were most effective. Biologicals cannot totally replace chemicals, but they can help to ease detrimental effects by reducing the overreliance on chemical fungicides." |
