Potential for using<i>Lecanicillium lecanii</i>for suppression of strawberry powdery mildew

Abstract

Augmenting native populations of the hyperparasite Lecanicillium lecanii suppressed powdery mildew of strawberry, caused by Sphaerotheca macularis f. sp. fragariae in California field trials. Repeated sprays significantly reduced disease compared to the untreated controls for periods of the fruit production season, suggesting possible use as a partial, but not total disease control strategy.
