Abstract
Hand transplanting onion requires significant labor but using PlantTape® could significantly reduce input cost, but production using this method has not been evaluated for herbicide tolerance and weed control. Herbicide options for weed control and transplanted Vidalia onion (Allium cepa L.) tolerance using PlantTape® establishment methods were evaluated in Georgia. Using PlantTape® technology and greenhouse grown onion seedlings allowed for rapid field mechanical transplanting. Oxyfluorfen, pendimethalin, and S-metolachlor, alone, and in combination, at multiple rates, were applied either on the day of, or 10 days after, transplanting. Either oxyfluorfen alone, regardless of rate, or used in combination with other herbicides, provided 92 to 99% cutleaf eveningprimrose (Oenothera iaciniata Hill) season-long control consistently for the day-of, and 10-days after transplant applications. Pendimethalin and S-metolachlor control of cutleaf eveningprimrose was inconsistent, and should not be applied alone for weed control in Vidalia onion. Injury in the form of plant stunting was noted with minor height reduction, but this was transient and did not affect growth. Production was reflective of weed control, with maximum onion bulb count and yield obtained with herbicide combinations of pendimethalin, oxyfluorfen, and S-metolachlor. PlantTape® technology can be used to establish Vidalia onion using current registered herbicides, but an emphasis on consistent transplants in the tape to ensure adequate stand is needed.
