| Abstract/Contents: | "Fenoxaprop effectively controls crabgrass (Digitaria spp.) in tall fescue (Festuca arundinacea L.) turf but antagonism with growth regulating herbicides reduces potential to apply fenoxaprop in combination with many herbicides registered for broadleaf weed control. Separate field experiments were conducted in Georgia, New Jersey, and Tennessee to investigate tank-mixtures of fenoxaprop with aminocyclopyrachlor or fluroxypyr for smooth crabgrass and white clover control. Rate titrations of fenoxaprop were applied with or without aminocyclopyrachlor in the first experiment or fluroxypyr in the second experiment. Fenoxaprop alone exhibited substantial activity on smooth crabgrass but control was greater with fenoxaprop + aminocyclopyrachlor treatments. By 4 and 6 WAT, approximately 22 and 44% less fenoxaprop was required to achieve 80% smooth crabgrass control when the herbicide was tank-mixed with aminocyclopyrachlor at 53 and 79 g ai ha-1, respectively. Fenoxaprop did not reduce white clover (Trifolium repens L.) control with aminocyclopyrachlor as 97% control was achieved by 4 WAT for all aminocyclopyrachlor + fenoxaprop treatments. In another experiment, smooth crabgrass control following treatment with mixtures of fenoxaprop and fluroxypyr was not significantly different than fenoxaprop alone. Smooth crabgrass control with mixtures of fenoxaprop with 2,4-D, plus dicamba, plus MCPP was nearly 50% less than fenoxaprop alone. White clover was completely controlled from mixtures of fenoxaprop and fluroxypyr which was similar to fenoxaprop applied with 2,4-D plus dicamba plus MCPP. Tall fescue was not injured from any treatment. Results suggest aminocyclopyrachlor enhances fenoxaprop efficacy for smooth crabgrass control in tall fescue while fluroxypyr may also be used in tankmixtures with fenoxaprop for broadleaf weed control." |
