Abstract
Abstract Normal use rates of atrazine (2‐chloro‐4‐ethylamino‐6‐isopropylamino‐s‐triazine) for weed control in corn ( Zea mays L.) applied for 3 consecutive years at three locations across Nebraska had no significant effect on corn yield or eight other corn yield components. Annual application rates of 9 kg/ha of atrazine during 1963–1965 caused a 21, 23, and 2% corn yield reduction in 1965 at Alliance, North Platte, and Lincoln, respectively. Generally there is a wide margin of safety when using atrazine to control annual weeds in corn.
