Aquatic CEU Update

Pesticide Mode of Action and Chemical Families
Jason Ferrell, Assistant Professor, Extension Weed Specialist, University of Florida, Gainesville.Herbicide toxicity to plants and people will be addressed. Proper handling and pesticide safety will also be discussed.

New Weeds to Watch For
Ken Langeland, Professor; and Collette Jacono, Aquatic and Invasive Plants, University of Florida, Gainesville. Identification, biology, and management of emerging and potential aquatic plant pests will be discussed

Ponds: Careful of the Fish
Charles Cichra, Professor, Fish Ecology and Management, University of Florida, Gainesville.This presentation will discuss factors affecting aquatic macrophyte and algal growth, with an emphasis on nutrients; the role of aquatic plants as habitat; the relationship between aquatic plants and fish abundance; the source, dynamics, and management of dissolved oxygen in aquatic systems; and how aquatic plants and their control can affect fish populations.

New Herbicides on the Horizon
William Haller, Professor, Invasive Weed Control, University of Florida, Gainesville. Herbicide resistance and herbicides that we have historically used in aquatic weed control will be discussed as well as best application techniques. Characteristics of the perfect aquatic herbicide which will include selectivity, non-target effects, downstream concerns and particularly irrigation issues will be discussed. Experimental Use Permits, rules and regulations and limitations of use, and data requirements will also be discussed. New modes of action of possible new products and current registration status will be covered.
