Potential New Fungicides for Control of Powdery Mildew of Cantaloupe - 1990 Evaluation

Abstract

Powdery mildew of cantaloupe, caused by the plant pathogenic fungus Sphaerotheca fuliginea, is usually found in some melon fields every year. Disease development is favored by low relative humidity, moderate temperatures, and succulent plant growth. In the spring of 1990, potential new fungicides were evaluated for disease control in a field trial All tested materials provided significant control when compared to untreated plants. Bayleton is the only tested material that is currently registered for use on cantaloupe for control of powdery mildew.
