Last week I wrote about the amine and ester 2,4-D formulations and that the ester formulation of 2,4-D have higher vapor pressures and tend to volatilize more than amines, therefore one should use an amine formulation when volatilization is a concern with sensitive plants. This week, I received an email about the DriftWatch program so I’ve included a recent press release from Tim Creger with the Nebraska Department of Agriculture below.

The Nebraska Department of Agriculture’s Pesticide Program would like to remind outdoor pesticide applicators – especially those applying volatile herbicides such as 2,4-D and dicamba – to be mindful of the increasing number of commercially-grown sensitive crops in our agricultural landscape.  Applicators are reminded to read and follow the label directions, including any timing, temperature, and wind speed restrictions.  In addition, please utilize DriftWatch™ to locate commercially-grown sensitive crops in your spray area, and adjust your application accordingly.  Sensitive crops include orchards, vineyards, fruits and vegetables, organic crops, nurseries, and tree crops.

DriftWatch™ is a voluntary service; however, new commercial crop locations are added frequently.  Applicators can register their business area in DriftWatch™, which then allows them to receive e-mail notifications when sensitive crops are added to their spray area.

All outdoor applicators should benefit from this service, including those making pesticide applications to roadsides, lawns and other turf sites, and agricultural fields. For more information about DriftWatch, go to the NDA’s website or call the NDA at (402) 471-6851.
