The results of two powdery mildew fungicide trials conducted in 2021 were just published in Plant Disease Management Reports. In these trials, 17 unique products were evaluated for performance against powdery mildew under greenhouse conditions (Fig. 1). Weekly disease incidence and severity was assessed one day prior to each of five fungicide applications and two weeks after the final application. Disease severity was based on the percent of the upper and lower leaf surfaces covered by visible mycelial growth of each fully emerged trifoliate leaf one week after the final fungicide application (Fig. 2). The full reports can be accessed here (Spring Trial, Summer Trial).
