Why You Need to Use A Preemergence Herbicide on Sugarbeet Fields in 2018
- Late spring requires use of a preemergence herbicide after planting when waterhemp is a production challenge.
- Use a chloroacetamide herbicide split lay-by with glyphosate and ethofumesate at the 2-4 lf sugarbeet stage followed by the 6-8 leaf sugarbeet stage.
- Control waterhemp escapes when they are small, less than 4-inches tall. Be aware that PowerMax and UpBeet do not control resistant biotypes; Betamix is in short supply.
- You may need to cultivate to control waterhemp escapes.
