Table: Suggested Rates for Betanex and Betamix with Consideration of Sugarbeet Size, Application Method, and the Presence of Soil Applied Herbicide
The rates are conservative and assume adequate soil moisture, healthy unstressed sugarbeet, and that the weeds emerge about the same time as the sugarbeet. Betanex or Betamix should be applied in late afternoon or evening and another application should be made 5 to 7 days later if needed. Rates in the table may need to be increased for a dry, cool environment or reduced for a hot, wet environment.
