Reasons for need: Dogbane, horsetail, bindweed, buckwheat, common mallow, Difficult to control weeds in highbush blueberries fit nicely.:08/23; NJ/ Excellent crop tolerance based on trial conducted in NJ in 2021 and 2022. Alternative to reluctantly used 2,4-D and glyphosate:08/23
Efficacy/Crop Safety (E/CS) Data Required: Mfg requires 'only CS data are needed from major blueberry growing states such as Michigan
E/CS Research Comments:
Comments: This new request is for spot spray or banded spray. Although PR# 08324 covers the spot spray, it has a Mfg Will Not Support status from 2002. This new request for both use patterns will be forwarded to the mfg for a current review:08/23; Mfg supports as "Potential, E/CS data before approval for Residue:08/23

Besancon, Thierry 22-NJ-DMP RECD 5612.pdf 8/23 Two-year trial with treatments applied to the same pots both years. Starane Ultra applied as a banded spray along ‘Draper’ blueberries established in a Downer loamy sand 6 years prior to trial establishment. Starane Ultra was applied twice per year, 30 to 45 days apart, at 11.2 or 22.4 fl oz/a (0.245 or 0.49 lb ai/a). Both rates controlled common grounsel significantly better than the glufosinate standard 14 and 28 days after first application (DAA). Fluroxypyr also provided significantly greater common purslane control at 7, 14 and 28 after the second application (DAB). Injury to new canes was similar or lower than glufosinate, regardless of fluroxypyr rate or evaluation timing. Little to no foliar injury occurred with fluroxypyr (3% or less). Berry yield, weight per berry and % commercial yield was not different between glufosinate and fluroxypyr treatments.
