Adequate soil moisture must be present at application, or furrow irrigate after treatment. If pigweed is the primary species, desmedipham alone provides better control than in a mixture with phenmedipham. Do not apply within 75 days of harvest. Does not have soil activity. Treat when sugarbeets have 4-6 leaves.
Thorough coverage is essential.
Leaf burn will occur if applied in hot weather. Effective on fiddleneck, knotweed, smartweed, and volunteer cereals. For broad spectrum control, apply in combination with another herbicide such as desmedipham. Treat cotyledon-stage beets for best results. Control is erratic if weeds are larger than 2-leaf stage.
