Postemergence Grass Control in Landscapes and Nurseries
Joe Neal | NC State University | 9/21/2018
Annual and perennial grasses can be selectively controlled in most broadleaf crops and landscapes using postemergence herbicides that control only grasses — chemicals often referred to as “postemergence graminicides.” There are four graminicides labeled for use in horticultural crops — fenoxaprop, fluazifop-p, sethoxydim, and clethodim. Each graminicide is systemic (translocated) and has short-term soil residual (about 2 weeks). Although each herbicide kills grasses in the same way (acting upon the same site of action), they differ in their effectiveness on some grass weeds, safety on crops, and labeled uses.
