Abstract

Subsurface application of liquid or granular formulations of ethyl N,N-dipropylthiocarbamate (EPTC) at planting time effectively controlled annual grass weed species in new seedings of alfalfa (Medicago sativa L.) and birdsfoot trefoil (Lotus corniculatus L.). Control of annual broadleaf weeds by EPTC was incomplete. A postemergence application of 4-(2,4-dichlorophenoxy)butyric acid (2,4-DB) in addition to the EPTC treatment resulted in excellent overall weed control. Benefits of weed control were more evident in birdsfoot trefoil than alfalfa.
