Broadleaf weed control in tribemiron tolerant sunflower with preemergence followed by sequential postemergence herbicides

摘要

Research plots were established on June 4, 2007 at the Agricultural Science Center, Farmington, New Mexico, to evaluate the response of tribenuron tolerant sunflower (var. Pioneer 63N81) and annual broadleaf weeds to preemergence followed by sequential postemergence herbicides. Soil type was a Wall sandy loam with a pH of 7.8 and an organic matter content of less than 1%. The experimental design was a randomized complete block with four replications. Individual plots were 4, 34 in rows 30 ft long.
