Combining Reduced Herbicide Rates and Cultivation for Effective Weed Control in Corn

Abstract

Though the combination of cultivation and reduced herbicide rates has been experimentally shown to offer effective weed control in corn, few New York field corn growers cultivate for weed control. In fact, according to a 1997 survey, most growers who do cultivate corn still use broadcast, full rate herbicides. Three on-farm experiments were performed in New York State in 1997 to demonstrate the effectiveness of banded herbicides and cultivation in protecting corn from weed-induced yield loss.
