Downy mildew (Pseudoperonospora cubensis) is a serious pathogen that causes significant damage to cucurbit crops, including melons. Research on downy mildew is particularly important in the context of increasing environmental regulations and pursuing sustainable agriculture. The present study aims at investigating the efficacy of fungicidal products and their impact on yields under field conditions in Bulgaria. The highest level of disease control was achieved with the application of a combination of Fluoxapiprolin at 0.75 L/ha and Cyazofamid at 0.5 L/ha, resulting in maximum disease suppression and high yield.
