My apology for an error in the last issue of the Crop and Pest Report in the discussion of Beyond use in Clearfield lentil and wheat crops. The following information is correct.

CLARIFICATION OF ADJUVANT USE WITH BEYOND IN WHEAT, LENTIL, AND SUNFLOWER

The following adjuvant clarifications were submitted by Dr Brian Jenks, Weed Scientist at the Northcentral R&E Center in Minot and these recommendations supersede all adjuvant recommendations in the ND Weed Control Guide:

General adjuvant use with Beyond herbicide in Clearfield spring wheat, lentil, and sunflower:

Add a NIS and a nitrogen based fertilizer.

Clearfield lentil: Do not use COC or MSO with Beyond on Clearfield lentil.

Clearfield wheat: Do not use COC or MSO with Beyond on Clearfield spring wheat. COC or MSO can be used on Clearfield Plus spring wheat and will improve weed control.
