Robinson, Allison 23-OH-DMP RECD 5685.pdf As part of a multi-crop screening trial, Rely herbicide was applied broadcast 14, 6, or 3 days preplant at 43 or 87 fl oz/a (0.79 or 1.59 lb ai/a) to seeded ‘Southern Curled’ mustard greens 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 seeded mustard greens in a clay soil. Glufosinate caused no crop injury, stand reduction or yield reduction.
Wang, Zheng 23-CA-DMP RECD 5693.pdf 02/24 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 mustard greens seeded in a Handford fine sandy loam. With the exception of 43 fl oz/a applied 14 days before seeding, all treatments caused significant stand reductions, up to 42%. Pooled across both rates and all application timings, moderate foliar injury (approximately 40%) did not significantly increase between 22 and 49 days after planting.
