Abstract
\r\n Cool-season weeds become a major problem on most bermudagrass sport fields. Although bermudagrass usually out competes weeds during the summer, winter weeds can dominate during the dormant season. This is both unattractive and can delay spring green up and result in turf that cannot stand up to heavy use during the summer season. Incooperation with the City of Fort Worth Parks and Community Services Department and the City of Arlington Parks and Recreation Department, post-emergent herbicide trials were conducted at two Bermuda grass sports fields in preparation for the 2011 spring season. Because the herbicide products applied were on fertilizer carrier, a fertilizer only treatment was included at each location. Treatments and product rates were untreated control, fertilizer only (Lesco 24-0-11 at 150#/A), The Andersons 15-0-5 plus 0.03% LockUp at 200#/A, The Andersons 19-0-2 plus 0.03% LockUp + 0.07% Dicamba at 200#/A, Lebanon 19-06 plus 0.01% Penoxsulam + 0.08% Dicamba + 1.04% 2,4-D at 175#/A and Lesco Momentum 21-0-11 plus 0.01% MCPA + 0.08% Dicamba + 1.04% 2,4-D at 150#/A. A randomized complete block design with three replications was used at each field. Evaluations of percent weed control were made at four and eight weeks after treatment. All treatments resulted in statistically significant weed control when compared to the untreated and fertilizer only blocks. None of the products injured the bermudagrass turf. This study suggests that easily applied granular herbicide products can be an effective tool to prepare sports fields for play.
