We are pleased to share this information from the National Water Quality Monitoring Council with our students:
"Changing Pesticide Use: Challenges for Water-Quality Monitoring and Ecological Implications" Featuring a presentation by Michelle Hladik, U.S. Geological Survey Research Chemist ABSTRACT:
Pesticide use is constantly changing due to pest resistance, regulations, crops planted, and the introduction of new chemicals. In the past few decades there have been changes in the types and amount of insecticides, fungicides, and herbicides used in agricultural and urban areas. In recent years, application techniques for agricultural use pesticides have also changed with an increase in seed coatings in addition to more traditional application methods such as foliar sprays. Most seeds coatings consist of one insecticide and up to five fungicides; many of these pesticides have not been used extensively prior to their inclusion on seed coatings. A change in the pesticide active ingredient or application technique can impact the environmental fate and transport of these pesticides and their potential effects on non-target organisms. For example, a shift in the mid-2000s from the pyrethroid to neonicotinoid insecticides required new analytical methods, sampling of different environmental matrices, and toxicological concerns focused on different species.
