Crop and herbicide rotation effects on weed population dynamics and the characterization of imidazolinone-resistant smooth pigweed (Amaranthus hybridus)
… pigweed plants in Painter, VA were treated with imazethapyr or nicosulfuron from 1992 to 1994, and no ALS-inhibitor-resistant plants were identified. Smooth pigweed in Marion, MD and Oak Hall, VA, and livid amaranth in Warren County, NJ were reportedly escaping control from imazaquin or …

A Study of the Effect of Herbicides on Mycorrhizae Associated With Native Warm Season Grass
Imazapic, imazethapyr, and imazapzyr were applied to seedlings of Tripsacum dactyloides, Andropogon gerardii, Panicum virgatum L., and Sorghastrum nutans (L.) Nash. growing in native prairie and sterile soil. All herbicide treatments caused a negative effect on plants and mycorrhizal colonization. …
