Anthracnose on Pepper in Florida

P. D. Roberts, K. L. Pernezny, and T. A. Kucharek

This document is about anthracnose disease in pepper plants, caused by fungi in the genus Colletotrichum. It describes the symptoms, disease cycle, and environmental conditions that favor its development, particularly during warm and wet weather. The document also outlines integrated management strategies for controlling the disease, including sanitation practices, crop rotation, use of pathogen-free seeds, and appropriate fungicide applications. Original Publication Date: September 2001.

Anthracnose Fruit Rot of Strawberry

James C. Mertely, Bruna B. Forcelini, and Natalia. A. Peres

Anthracnose fruit rot, caused by the fungus Colletotrichum acutatum, is an important disease for strawberry production worldwide. Other species of Colletotrichum, such as C. fragarie and C. gloeosporioides, are less frequently involved in fruit rot. Although fruit rot is the most important symptom caused by C. acutatum, the fungus can also attack other parts of the plant including the crown, leaves, petioles, and roots.

Colletotrichum Crown Rot (Anthracnose Crown Rot) of Strawberry

Natalia A. Peres, M. S. Oliveira, and Steven J. MacKenzie

Describes this serious disease of strawberries in warm production region, its causal agent and symptoms, disease development and spread, and control. Includes a table of products labeled for control of colletotrichum crown rot.

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.

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.
