| Abstract/Contents: | "Pollinators are estimated to contribute over $117 billion globally and $8 billion in the US annually through improved crop production. The recent decline in pollinator abundance may impact global food production. Several common weeds of managed turfgrass systems attract pollinators, and these systems are often treated with insecticides that may harm pollinators. Field studies were conducted in 2021 and 2022 to evaluate the effect of various herbicides and herbicide-formulation constituents on pollinator foraging of white clover (Trifolium repens L.) flowers in managed tall fescue turf. Three separate experiments were implemented in Blacksburg, VA, as randomized complete block designs with six replications and seven treatments. Treatments included a nontreated control; MCPP; 2,4-D; dicamba; Trimec ClassicTM (2,4-D, MCPP, dicamba); SpeedzoneTM (carfentrazone, 2,4-D, MCPP, dicamba); and a formulation blank (inert ingredients of SpeedzoneTM). Plots were 3.2 m-2 and spaced 3 m apart with 6 m between blocks. All flowers in each plot were counted each morning, starting one day before treatment and ending 6 days after treatment (DAT). All insect foragers observed for one minute were recorded for each plot three times each day (10:00am, 1:00pm, and 4:00pm). Flower quality was visually rated for three flowers in each plot, and petal necrosis was calculated via digital image analysis each day. The formulation blank did not alter white clover flower density or quality compared to nontreated plots; however, all herbicides reduced white clover flower density equivalently, with complete reduction occurring 4 to 5 DAT. Furthermore, honey bees and other insects vacate herbicide-treated areas in less than 2 DAT, even though the loss of floral density and petal discoloration were observed at a much slower pace of 4 to 5-DAT. Research findings improve our understanding of best practices to mitigate bee exposure to insecticides by demonstrating rapid (2-d) insect evacuation in areas treated with auxin herbicides." |
