Grumet et al.
R. Grumet is the lead PI for the USDA-SCRI CucCAP project: CucCAP: Leveraging applied genomics to increase disease resistance in cucurbit crops. The primary objectives of the CucCAP project are to develop genomic and bioinformatic breeding tool kits for accelerated crop improvement across the Cucurbitaceae; use these tools to facilitate introgression of disease resistance into commercially valuable cucurbit cultivars; and provide readily accessible information to facilitate disease control.
Fusarium wilt on melon
Fusarium wilt of melon is caused by Fusarium oxysporum f. sp. melonis (FOM). It is considered one of the more important diseases of melon in the United States. There are currently no economical or even viable chemical control strategies or methods that can control this soil-borne pathogen. For information about Fusarium wilt on melon, visit […]

Virus diseases of Squash
Watermelon mosaic virus Papaya ringspot virus Zucchini yellow mosaic virus Cucumber mosaic virus (CMV) Watermelon mosaic virus This aphid-transmitted virus can infect and produce symptoms on all commercially grown cucurbits. This virus causes milder symptoms on the foliage of most infected plants. Growers have seen a lessening of foliar symptoms following fertilization. Fruit distortion and […]
Downy mildew on melon
Pseudoperonospora cubensis Downy mildew causes angular, yellow to brown lesions on top of the leaves that are restricted by leaf veins. When conditions are favorable, for example early in the morning when moisture is higher, lesions observed on the underside of the leaf may be covered in dark “down”. This downy growth is masses of […]
Powdery mildew on cucumber
Podosphaera xanthii Cucurbit powdery mildew is caused worldwide by the fungal pathogens Podosphaera xanthii and Golovinomyces cichoracearum. Podosphaera xanthii is more common¹ and, apparently, may be the only one on cucurbits in North America². Early symptoms of powdery mildew include small, circular, yellow lesions on leaves and petioles. Lesions quickly become covered in white spores and […]
