摘要: Abstract Field studies were conducted in Louisiana and Mississippi 2009 2010 to evaluate coapplications of glyphosate, pyrithiobac, residual herbicides on growth yield glyphosate-resistant cotton. Treatments a factorial arrangement glyphosate (0 860 g ae ha−1), pyrithiobac 470 ai two (pendimethalin [1,120 ha−1], S-metolachlor [1,070 no herbicide). Cotton injury was greatest 3 d after treatment (DAT) decreased at each evaluation interval until 28 DAT when coapplied with glyphosate. ranged from 4 17% through 14 applied alone (no herbicide) or pendimethalin, but ≤ 3% DAT. 21 following plus 31%, injured cotton 1 7%. When included, 15% greater than that fo...
