Disease Control for Snap Beans in Florida

Shouan Zhang, Nicholas Dufault, Mathews Paret, Pamela Roberts, Guodong Liu, and Qingren Wang

This publication suggests a sequential disease control program for snap beans in Florida. Postharvest disease problems are addressed only to the extent that they are affected by field practices. The application of the following sequential control program should minimize yield losses for the majority of plantings.

Amanda Strayer-Scherer, Ying-Yu Liao, Peter Abrahamian, Sujan Timilsina, Mathews Paret, Tim Momol, Jeff Jones, and Gary Vallad

Bacterial spot is one of the most detrimental diseases of tomato and is especially severe in the southeast United States when weather conditions (high temperature, high humidity, and rain) become conducive for disease development. This publication presents updated information about the causal pathogen and management of bacterial spot on tomato in Florida.

Ginger, Galangal, and Turmeric Production in Florida

Paul Fisher, Rosanna Freyre, Celina Gómez, Brian Pearson, Tatiana Sanchez-Jones, Shawn Steed, Wanda Laughlin, Robert Hochmuth, Jeff Wasielewski, Deah Lieurance, Carrie Harmon, Mathews Paret, Lance Osborne, Kevin Athearn, Steven Sargent, Mengzi Zhang

Ginger, galangal, and turmeric (Figure 1) are emerging crops for Florida production. All of these plants are in the Zingiberaceae family and share most aspects of their production. This publication describes production in containers or the field under Florida conditions to help guide growers interested in ginger, turmeric, and galangal production or expanding their market. All species have been evaluated by the UF/IFAS Assessment of Non-native Plants in Florida’s Natural Areas (UF/IFAS Assessment) using the Predictive Tool (an invasion risk assessment) and all present a low risk of invasion in Florida (https://assessment.ifas.ufl.edu).

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.
