Use Soil-Applied Herbicides with May Planted Sugarbeet (05/09/19)

Sugarbeet planting date dictates the weed control strategy – especially when waterhemp is the most important weed control challenge.

Sugarbeet planting date dictates the weed control strategy – especially when waterhemp is the most important weed control challenge. Waterhemp germinates and emerges in response to accumulated growing degree days or emerges approximately May 20 in Minnesota and eastern North Dakota. May planted beets simply will not achieve the 2-lf stage for S-metolachlor, Outlook or Warrant application before waterhemp emerges. That means sugarbeet growers need to use soil-applied herbicides applied at planting or after planting and before sugarbeet emerge. Consider the following options.
