| Abstract/Contents: | "Current recommendations for pasture renovation to non-toxic endophyte tall fescue (Festuca arundinacea) will cost producers' $200/ac, and three years improved animal productivity are necessary to defray expenses. Herbicide resistant corn allows the integration of no-tillage corn (Zea mays) production as a component in the no-tillage pasture renovation system. This will minimize renovation costs if economically positive grain yield is obtained. Herbicide control of winter and early spring vegetation is essential for stand establishment and plant vigor in no-tillage systems. In addition, warm season perennial grasses must be controlled to promote maximum grain yield. Field research was contucted at the Pontotoc Ridge-Flatwoods Branch Experiment Station, Pontotoc, MS in 2001 to evaluate weed management in no-tillage corn as a no-tillage pasture renovation system component. Preemergence burndown treatments included 1 lb/A glyphosate or 0.625 lb/A paraquat applied alone and tank-mixed with 1.2 lb/A metolachlor plus 2.0 lb/A atrazine and 0.6 lb/A metolachlor plus 1.0 lb/A atrazine. At 3 WAP (weeks after planting), postemergent treatments included at least 0.75 lb/A glyphosate alone and tank-mixed with either 3.0 lb/A simazine, 0.5 lb/A 2,4-D amine, or 0.02 lb/A primisulfuron + 0.02 lb/A prosulfuron. At 2 WAP, tall fescue control was at least 92% with all preemergence burndown treatments. Glyphosate alone or tank-mixed controlled dallisgrass (Paspalum dilatatum) at least 98% and bermudagrass (Cynodon dactylon) at least 85%, but conrol with paraquat alone or tank-mixed was less than 36%. At 7 WAP, all treatments controlled tall fescue at least 98%. Dallisgrass control was at least 92% with all treatments that included postemergence glyphosate alone and tank-mixed, except for paraquat followed by glyphosate + primisulfuron + prosulfuron. Bermudagrass control was at least 90% with treatments that included postemergence glyphosate, except for paraquat followed by glyphosate + primisulfuron + prosulfuron, glyphosate + 2,4-D amine, and glyphosate + simazine. Treatments that did not include postemergence glyphosate controlled dallisgrass and bermudagrass less than 38%. The highest grain yield was 134 bu/A with sequential glyphosate applications, suggesting the addition of a tank-mix partner is not necessary if postemergence application timing corresponds to appropriate weed species and size." |
