Anthracnose on Cucurbits in Florida

Pamela D. Roberts, Gary Vallad, Shouan Zhang, Nicholas Dufault, and Mathews Paret

Watermelon (Citrullus lanatus), cantaloupe or muskmelon (Cucumis melo), squash (Cucurbita pepo), bitter gourd (Momordica charantia), and cucumber (Cucumis sativa) are commonly grown throughout Florida on both commercial farms and home gardens, while pumpkin (Cucurbita maxima) production is largely limited to north Florida.  Anthracnose on cucurbits, caused by the fungus Colletotrichum orbiculare, is a common disease that occurs worldwide and throughout Florida. While all cucurbits are susceptible to the disease, cucumber, cantaloupe, and watermelon are most frequently affected. This EDIS document provides information regarding the pathogen, disease cycle, diagnostics and symptoms, and an overview of management of this disease on cucucurbits.

Evaluating Pomegranate Cultivars for Resistance to Anthracnose Fruit Rot, a Severe Fungal Disease in Florida and Southeast United States

Alexander Schaller, Zhanao Deng, Gary E. Vallad, and John M. Chater

Pomegranate (Punica granatum L.) has primarily been cultivated at home in Florida and other southeastern states. Over the past 15 years, growers, nurseries, researchers, and Extension agents have explored the potential of pomegranate as an alternative fruit crop. Early field trials revealed that pomegranates are highly susceptible to Colletotrichum gloeosporioides, causing severe anthracnose fruit rot and premature fruit drop. The development and use of disease-resistant cultivars are considered some of the best methods to manage this disease. This publication presents our findings from evaluating 35 pomegranate cultivars under natural disease pressure in central Florida and by artificial inoculation. The susceptibility of such pomegranate cultivars varied widely, with six exhibiting resistance to anthracnose fruit rot. More comprehensive research is warranted to further develop anthracnose-resistant cultivars and to enhance our understanding of disease resistance in this crop.
