  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.

• 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.
