Chemical weed control strategies for sweet corn in Tükye'ris diverse production areas

Sweet corn production in T & uuml;rkiye is failing to match growing demand from consumers and the food industry. Weeds severely limit sweet corn production, yet only a single herbicide is registered in T & uuml;rkiye. Due to labor costs, hand weeding is no longer affordable and growers are demanding cost-effective weed control strategies for sweet corn production. Nine treatments including preemergence (PRE) and/or postemergence (POST) herbicides were tested across the country's diverse growing environments. Compared to the weedy control, all treatments increased the number of marketable ears. Only two treatments-s-metolachlor plus terbuthylazine followed by isoxaflutole plus cyprosulfamide plus theincarbazone-methyl and dimethenamid followed by mesotrione plus nicosulfuron-provided consistent late-season weed control and fully protected crop yield. This study quantifies the value that additional herbicide registrations in T & uuml;rkiye could have for controlling problematic weeds in the country's sweet corn production.
