| Abstract/Contents: | Trials were initiated on established turfgrass to evaluate pre- and postemergent herbicides for control of smooth crabgrass [Digitaria ischaemum (Schreb.) Muhl.]. The effects of rate, formulation, application date, and application frequency were investigated. Effectiveness of treatments was based on percent crabgrass control and turfgrass injury. In the preemergent test, bensulide, butralin, DCPA, diclofop, and prosulfalin provided excellent control (90-100%). A second application of bensulide or DCPA was not needed to obtain seasonal control. Wettable powder formulations of DCPA caused more injury than granular formulations. Certain rates and formulations of oxadiazon gave excellent control, and 2% granular formulations provided better control than their 5% counterparts. Benefin applications at 3 lb ai/A resulted in good (80-89%) to excellent control. May application of benefin or oxadiazon resulted in greater turf injury than March application. Siduron provided excellent control when applied in May, but less control when applied in March. Excellent postemergent control was achieved with two applications of DSMA or MSMA. Diclofop provided less control and resulted in objectionable turf injury. DPX-4129 provided poor control (less than 70%), but higher rates could be investigated. Surfactant applications at several rates and frequencies resulted in no effective crabgrass control. |
