Abstract

Wheat (Triticum aestivum L. ‘Waldron’) tolerance to barban (4-chloro-2-butynyl m-chlorocarbanilate) applied at 0.42 to 3.36 kg/ha 4 to 24 days after crop emergence was determined in the field and greenhouse and barley (Hordeum vulgare L. ‘Nordic’) tolerance in the field only. Wheat and barley tolerance to barban increased as application was delayed from 4 to 16 days after emergence. Wheat yields were reduced by barban at 0.84 kg/ha applied 4 days after emergence or by 1.68 and 3.36 kg/ha applied 4, 8, and 12 days after crop emergence. However, barban applied 16, 20, and 24 days after crop emergence did not reduce wheat yield regardless of barban rate. Barley yields were reduced by 1.68 kg/ha barban applied 4, 8, 12, and 16 days after emergence or by 3.36 kg/ha applied at all dates; however, greatest yield reductions occurred with applications 4, 8, and 12 days after crop emergence.
