| Abstract/Contents: | "Lesser swinecress (Coronopus didymus (L.) Sm.) is a summer annual or biennial broadleaf weed that emerges from February to October with peaks of emergence in April and September. Tolerance to low mowing, heavy traffic, and prolific seed production has increased the prevalence of this weed in turfgrass environments. Field experiments were conducted at the Pecos County Municipal Golf Course in Fort Stockton, TX in the summer of 2009 to examine the postemergence control of lesser swinecress. Studies were located on established infestations of lesser swinecress present in a 'L-93' creeping bentgrass putting green cut to a height of 0.3 cm. Plots measured 1.5 x 1.5 m and were arranged in a randomized complete block design with three replications of treatments. Treatments were applied using a CO2 backpack sprayer equipped with XR8004VS nozzle tips and calibrated to deliver 375 L/ha at 221 kPa. Treatments were initiated on June 19, 2009 and consisted of single or sequential applications of MCPP + 2,4-D + dicamba at 0.5 kg ae/ha, sulfentrazone at 0.14 kg ai/ha, and carfentrazone at 0.017 kg ai/ha. Sequential applications of MCPP + 2,4-D + dicamba were made on July 17, 2009. Visual estimates of percent lesser swinecress control and creeping bentgrass phytotoxicity were taken 1, 2, 4, 6, and 8 WAIT. Data were subjected to analysis of variance (ANOVA) and means were separated using Fisher's Protected LSD at the 0.05 significance level. No creeping bentgrass phytotoxicity was observed throughout the length of the trial regardless of treatment or application timing. Carfentrazone treatments exhibited 0% control throughout the length of the trial. MCPP + 2,4-D + dicamba and sulfentrazone treatments exhibited 82 to 84% control 2 WAIT. Control with sulfentrazone decreased to 11% 8 WAIT. Control remained constant (83%) with single applications of MCPP + 2,4-D + dicamba, while sequential applications increased control to 91% 8 WAIT." |
