| Abstract/Contents: | "Mugwort (Artemesia vulgaris) is a major perennial weed of field nursery in New Jersey with limited chemical control options under grower's conditions. Two rates (X and 1.5X) each of clopyralid (Stinger) (9 & 14 oz/A), clopyralid + 2,4-D (Weedar 64) (9 + 16 & 14 + 16 oz/A), clopyralid + 2,4-D + dicamba (Millennium) (44 & 65 oz/A), clopyralid + dicamba + MCPA (Trupower) (44 & 65 oz/A), and dicamba + MCPA + triclopyr (Coolpower) (52 & 78 oz/A) were applied for mugwort control at 4, 6, and 8 weeks after planting (WAP). An untreated control was added for comparison. Herbicides were applied with a calibrated greenhouse sprayer fitted with 8002VS-nozzle tip and operated at 30 psi and 68 gpa. Mugwort was raised under greenhouse conditions (75 to 90°F day, 60 to 70°Fnight, 14 to 16 h light) from 3- to 4-inch rhizome fragments planted in 2-gal plastic pots filled with regular mix (2:1 v/v peat moss:vermicullite mix plus lime, fertilizer, and micronutrients). The experiment was set up in four randomized complete blocks. Mugwort control was assessed based on foliage dry weight (live portions only) four to eight weeks after herbicide application as well as dry weight of regrowth five weeks after top renewal. All herbicide treatments applied 4 WAP controlled mugwort 100% within four weeks after treatment. With herbicide application 6 WAP, Trupower and Millennium controlled mugwort more then 95% within six weeks after treatment while Coolpower, Stinger or Stinger + 2,4-D caused 90 to 95% control. When applied 8 WAP, Millennium, Trupower or Coolpower caused only 60 to 67% control four weeks after treatment and Stinger or Stinger + 2,4-D killed less than 50% mugwort foliage. When observed for five weeks after top removal, there was no regrowth from all herbicide treatments applied at 4 or 6 weeks WAP except Coolpower applied 6 WAP at 52 oz/A which produced regrowth with dry weight 2.1% of untreated control. When mugwort was treated 8 WAP, Millennium caused the least regrowth of approx 0.5% dry weight of untreated control followed by Stinger + 2,4-D (2.2%), Trupower (3.8%), Stinger (4.1%) and Coolpower (48.5%). It was concluded that all the herbicides tested are effective for the control of 4- to 6-week old mugwort at the rates evaluated, but for 8-week old mugwort stands, Millennium is the most effective, followed by Stinger + 2,4-D, Trupower, and Stinger in that order. Coolpower, a non-clopyralid containing herbicide mixture, is ineffective at 52 to 78 oz/A for the control of 8-week old mugwort stands." |
