Abstract

Field experiments were established to investigate the influence of terbufos on the response of five corn hybrids to postemergence applications of CGA-136872. In 1987, Asgrow RX404, Dekalb DK656, Funk's G4673A, and Pioneer P3165 were tolerant to CGA-136872 when no soil insecticides were applied. In 1988, terbufos was applied at 1.1 kg ai ha-1 in-furrow at planting. Injury was observed on all hybrids following CGA-136872 application in 1988. With the exception of Funk's G4307, all hybrids were tolerant to CGA-136872 in 1989 when no soil insecticide was used. When terbufos was applied in-furrow, injury increased with increasing herbicide rate for these hybrids.
