| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Good IPM Fit; A postemergence application that allows the field to be scouted and determine if an application is needed. As a postemergence application it is compatible with a mechanical weeding (cultivation) and is applied at a time that minimizes pesticide runoff. Tolpyralate is a herbicide mode of action that is not registered for many specialty crops, so this is opportunity to use an alternative MOA for sweet potato:08/23
|
| Reasons for need: |
Postemergence control of Amaranthus species and other broadleaf weeds; Currently no herbicide is registered for postemergence applications in sweet potato and this crop is slow to provide sufficient canopy to compete with later emerging weeds:08/23; NJ/Developing sweet potato NJ industry would benefit from an effective herbicide for control of pigweeds, especially Palmer amaranth:09/23

| Requesting State(s): |
AR:Bertucci, M ; DE:VanGessel, M* ; MS:Shankle, M ; NC:Smith, C ; NJ:Besancon, T ;
|
| PCR Use Pattern: |
Make one or two broadcast applications over crop at small broadleaf weeds (5" or less in height) at 1 to 1.35 fl oz/a. Retreatment interval should be at least 14 days. See label for guidance on adjuvant type and rate
