Abstract

BACKGROUND: Herbicides are the primary weed management method for processing vegetable growers, but challenges such as limited chemical options, herbicide resistance, crop injury risks, regulatory changes, and shifting consumer preferences are driving interest in nonchemical alternatives like laser weeding. In 2024, three research trials in New Jersey and New York evaluated the effectiveness of laser weeding using a commercial unit and comparing it with pre-emergence- and postemergence-applied herbicides on beet (Beta vulgaris L.), spinach (Spinacia oleracea L.), and pea (Pisum sativum L.).
