Abstract/Contents:"Two field studies were conducted to evaluate postemergent control of various broadleaf weeds in turf. The first study evaluated the control of dandelion (Taraxacum officinale Weber) with DPX-6025 and DPX-6316 in combination with 2,4-D, dicamba, or MCPP and commercial herbicide combinations. The second study evaluated the control of dandelion, and white clover (Trifolium repens L.) with experimental and commercial herbicide combinations. Control was determined by comparing the percent dandelion and clover cover at the time of application to the percent cover at the time of rating. A randomized complete block design with three replications was used in both studies. Plots were 3 by 10ft in the first study and 3 by 8 ft in the second study. All treatments were applied with a compressed air powered hand held boom with two 6502 flat fan nozzles spaced 18 inches apart and delivering 655 1/ha. The first study was not irrigated and moisture stress occurred frequently during the test. The second test received enough irrigation to sustain growth. Treatments in the first study were applied July 30 and rated 10 weeks later. 2,4-D + 2,4-DP + dicamba, 2,4-D + MCPP + dicamba, DPX-6025 + 2,4-D, and DPX-6025 + nitrogen controlled dandelion 80 percent or better. All other treatments provided fair to moderate control, except for all rates of DPX-6316 + nitrogen and the lowest rate of DPX-6025 + nitrogen, which had no control. Treatments in the second study were applied July 12 and rated 13 weeks later. 2,4-D + 2,4-DP + dicamba and triclopyr + 2,4-D (ester) provided excellent control of dandelion and 2,4-D + 2,4-DP + MCPP, triclopyr + 2,4-D (amine) and MCPA + MCPP + dicamba provided good control of dandelion. 2,4-D + 2,4-DP + dicamba, 2,4-D + 2,4-DP + MCPP, MCPA + MCPP + 2,4-DP, and triclopyr + 2,4-D (amine) provided excellent control of white clover while slightly less control was found for triclopyr + 2,4-D (ester). It can be concluded from these experiments that control of dandelion (70%) can be accomplished using 2,4-D + 2,4-DP + dicamba, MCPA + MCPP + dicamba, triclopyr + 2,4-D (ester), triclopyr + 2,4-D (amine), 2,4-D + MCPP + dicamba, DPX-6025 + nitrogen, and DPX-6025 + 2,4-D. When control of white clover is also considered, 2,4-D + 2,4-DP + dicamba, 2,4-D + 2,4-DP + MCPP, and ttriclopyr + 2,4-d (ester) provided at least 70 percent of both weeds."
