Turfgrass as a possible route for pollinator exposure to lawn applied imidacloprid
Jonathan Gunn, junior in the Department of Animal and Dairy Sciences, evaluated pollinator exposure to insecticides. His objective was to explore guttation, a process by which grasses exude moisture, as a possible route for pollinator exposure of a lawn-applied insecticide call imidacloprid. Sod was harvested and transferred to plastic flats to simulate field conditions. Turfgrass was sub-irrigated with and without an application of imidacloprid. Guttation fluid was collected. While the results indicate insecticide levels were significantly lower than concentration levels reported lethal to the European honey bee and the insidious flower bug, similarly low concentrations have been associated with sub-lethal effects in honey bees. Future research will evaluate insecticide concentrations of more commonly broadcast foliar applications. James McCurdy, assistant professor in the Department of Plant and Soil Sciences, served as Gunn's advisor.
