Comparing spp. Fungicide Resistance Profiles in Florida and East China Cucurbit Production Systems.

Gummy stem blight, caused by spp., is a major disease of cucurbits in the United States and China that is managed primarily through the use of fungicides. The objective of this study was to monitor and compare the recent fungicide resistance profiles of spp.

Evaluation of Rotational Biopesticide Programs for Disease Management in Organic Cucurbit Production.

Downy mildew (Pseudoperonospora cubensis) and powdery mildew (Podosphaera xanthii) are two of the most economically important and widespread cucurbit diseases. Disease management relies primarily on fungicide use, but frequent fungicide applications can lead to the development of resistant pathogen populations. In addition, more vegetables are being produced with organic practices, which prohibit the use of many fungicides.
