摘要: Past research has shown that a postemergence (POST) mixture of residual herbicide, such as Smetolachlor, with glyphosate can result in improved weed control and maximize cotton yield. Published is limited on the tolerance POST an aqueous capsule suspension (ACS) formulation pendimethalin applied at different growth stages to cotton. Research this issue important producers continue search for cost savings production, inclusion herbicides planting regimen needed abate expansion glyphosate-resistant (GR) weeds. This was conducted 2006 2007 evaluate effects combinations ACS second-generation GR growth, development, Treatments evaluated study included factorial arrangement [glyphosate (®Roundup Weathermax) 1540 g ha -1 alone or combination (®Prowl H2O) 1064 2128 S-metolachlor (Dual Magnum) ] stage (4- 5- 6- 8-leaf). Ammonium sulfate 2524 each treatment. Results indicated visual crop response form veinal yellowing slight leaf malformation be observed following tank-mixture glyphosate. Response contacted leaves. Visual minimal 21 d after both application timings not manifested reductions plant height seedcotton yield compared alone.
