Weeds of the EAA

Welcome to the weed science website of the Everglades Research and Education Center, Institute of Food and Agricultural Sciences, at the University of Florida. The Everglades Research and Education Center is located in the city of Belle Glade within the Everglades Agricultural Area (EAA).

The EAA is a dynamic agriculturally diverse region with major production of sugarcane, rice, commercial sod, and winter vegetables located on the southern edge of Lake Okeechobee in south Florida . Today, the EAA covers 700,000 acres dominated by organic or muck soils (Histosols).

This website is intended to help county extension faculty, growers, consultants, agribusiness personnel, and other stakeholders with information on sustainable weed management practices in the EAA and surrounding areas of south Florida. Weed management in sugarcane and vegetables, herbicide stewardship, proper sprayer calibration, and correct weed identification are the major focus of the extension program. The research program focuses on solving current and potential weed management problems in sugarcane and vegetables. Management of potential bioenergy crop escapes in sugarcane and vegetables is also pursed by the research program.

Extension
Weed - Insect interactions
Extension activities center on a proactive program to deliver the latest information on weed control and related topics to county extension faculty, growers, consultants, agribusiness personnel, and other stakeholders.Modes of delivery include traditional hard-copy publications, grower meetings, field days, and web-based Electronic Data Information Source (EDIS) of the University of Florida-IFAS Extension. See our home page for the Events Calendar.

Research Science Research

Research focuses on development of effective integrated weed management programs for sugarcane, rice, and commercial sod in both organic and mineral soils of southern Florida. Other crop responsibilities include weed management programs for vegetables and biofuel crops grown in the region. Specific research areas include biology of weed-crop interactions, weed ecology, soil-herbicide interactions, evaluation of herbicides, and interaction between pest management strategies.
