N2 - The comparative toxicity of 17 commonly used turfgrass pesticides and recovery of earthworm populations following exposure were studied for 2 yr in Poa pratensis turf. A single application of the fungicide benomyl or the insecticides ethoprop, carbaryl, or bendiocarb at labeled rates reduced earthworm populations by 60-99%, with significant effects lasting for at least 20 wk. These compounds also significantly reduced the rate at which earthworms incorporated mineral soil into buried pieces of thatch. None of the herbicides tested significantly affected earthworm populations. Abundance of Cryptostigmata, Collembola, and ants also was drastically reduced by some treatments. -from Authors
