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 […]
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.

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 […]
Papaya ringspot virus
Papaya ringspot virus (PRSV) belongs to the genus Potyvirus, a large and economically important group of plant infecting viruses in the family Potyviridae. PRSV is transmitted in fields by aphids. Insecticide application is not effective for disease control. The most effective and economic management strategy would be through the use of a disease-resistant cultivar. CucCAP’s watermelon […]
Cucumber mosaic virus
CMV causes a systemic infection in most host plants. Symptoms of cucumber mosaic can vary greatly depending on the crop infected and the age of the plant when infection occurs. For more information about plant viruses visit the Emerging Viruses in Cucurbits Working Group (EVCWG) website and the CucCAP Melon page. Infomation about CMV CucCAP: Breeding Cucumber […]
