Robinson, Allison 23-OH-DMP RECD 5685.pdf As part of a multi-crop screening trial, Rely herbicide was applied broadcast 14, 7, or 3 days preplant at 43 or 87 fl oz/a (0.79 or 1.59 lb ai/a) to transplanted ‘Platinum Destiny’ cabbage in a muck soil. Glufosinate caused no crop injury, stand reduction or yield reduction.
Pena, Marco 23-AZ-DMP RECD 5664.pdf As part of a multi-crop screening trial, Rely herbicide was applied broadcast 14, 7, or 3 days preplant at 43 or 87 fl oz/a (0.79 or 1.59 lb ai/a) to transplanted ‘Supreme Vantage’ cabbage in a clay soil. Glufosinate caused no crop injury, stand reduction or yield reduction.
Wang, Zheng 23-CA-DMP RECD 5693.pdf As part of a multi-crop screening trial, Rely herbicide was applied broadcast 14, 7, or 4 days preplant at 43 or 87 fl oz/a (0.79 or 1.59 lb ai/a) to cabbage transplanted in a Handford fine sandy loam. Glufosinate caused no significant stand reduction in cabbage, regardless of rate or timing. When pooled across both rates and all application timings, slight foliar injury was seen 22 days after planting (DAP), but increased to more than 50% at 49 DAP.
