Abstract

Where sugar beets followed the year after one year's use of 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine), the carryover, measured by beet response was correlated with the time, the method, and the rate of atrazine used, and the time of plow-down. Where beets were the second crop after an atrazine application, carryover was correlated with the rate of application only. Carryover was greatest following two consecutive years' use of atrazine. Sugar beets were more sensitive to atrazine than were soybeans, navy beans, or oats.
