Management of Powdery Mildew on Cantaloupe: Efficacy of Fungicides in 1995 Field TrialPowdery mildew of cantaloupe and other melons in Arizona is caused by the plant pathogenic fungus Sphaerotheca fuliginea. The disease is found in melon fields each year; however, the incidence and severity of the disease is quite variable. Disease development is favored by low relative humidity, moderate temperatures, and succulent plant growth. Potential new fungicides were evaluated for disease management in a field trial conducted in the spring of 1995. In this study, BAS-490 and Reach provided the highest level of efficacy among the materials and rates tested. Generally, lower levels of disease led to increased yield of marketable fruit.
