Title: Applying butylate- and EPTC-impregnated fertilizer to a cover crop for weed control in no-till corn, Zea mays L.
Abstract: Herbicides used for weed control in no-till corn are generally restricted to materials that are applied preemergence and postemergence. This study was conducted to determine the effectiveness of preplant-incorporated herbicides when impregnated on dry fertilizer and surface-applied to a winter cover crop at corn planting. Butylate plus atrazine or EPTC plus atrazine impregated on dry fertilizer and surface-broadcast reduced weeds and produced greater grain and silage yields than did untreated areas. Butylate or EPTC applied alone were not as effective as combinations with atrazine but did increase yield and weed control over untreated areas. When impregnated on dry fertilizer and placed in a standing small-grain cover crop, preplant-incorporated herbicides such as EPTC and butylate, when applied in combination with atrazine, reduced weed populations to levels similar to those with surface-applied herbicide combinations such as metolachlor plus atrazine or alachlor plus atrazine.
