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.

Chun-Hsiang (Sean) Wang, Mason J. Newark, Nicholas S. Dufault, Jeffrey A. Rollins, Fanny B. Iriarte, Robert Hochmuth, Danielle Treadwell, yMathews Paret

Alternaria leaf blight is a persistent and economically damaging foliar disease of cultivated carrot in Florida, capable of causing disease severity up to 95% and leading to significant yield loss through defoliation and mechanical harvest failure. This publication provides commercial carrot producers, county Extension faculty, crop consultants, and other agricultural professionals with current information on the disease. Integrated management strategies are detailed, including cultural controls, certified seed selection, and specific fungicide programs tailored for both conventional and USDA-certified organic production systems. Emphasis is placed on proper disease diagnosis and fungicide resistance management to assist producers in making effective management decisions.

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).
