Abstract Title: AMINOPYRALID: A NEW HERBICIDE FOR SELECTIVE BROADLEAF WEED CONTROL AN INTRODUCTION AND EFFICACY SUMMARY. Cassey Mattke, Vernon B. Langston, Pat Burch, Vanelle Peterson, W. N. Kline, M. B. Halstvedt, Dow AgroSciences, LLC. Indianapolis, IN.
Abstract Text: Aminopyralid is a new systemic herbicide developed by Dow AgroSciences specifically for use on rangeland, pasture, rights-of-way, such as roadsides for vegetation management, Conservation Reserve Program acres, non-cropland, and natural areas. The herbicide is formulated as a liquid containing, 240 g ae/liter of aminopyralid as a salt. The herbicide has postemergence activity on established broadleaf plants and provides residual control of germinating seeds of susceptible plants. Field research has shown aminopyralid to be effective at rates between 52.5 and 120 g ae/ha, which is about 1/4 to 1/20 less than use rates of currently registered rangeland and pasture herbicides with the same mode of action including, clopyralid, 2,4-D, dicamba, picloram, and triclopyr. Aminopyralid controls over 40 species of annual, biennial, and perennial broadleaf weeds including Acroptilon repens, Artemisia absinthium, Carduus acanthoides, Carduus nutans, Centaurea diffusa, Centaurea maculosa, Centaurea solstitialis, Chrysanthemum leucantheum, Cirsium arvense, Cirsium vulgare, Lamium amplexicaule, Matricaria inodora, Ranunculus bulbosus, Rumex crispus, Solanum carolinense, Solanum viarum, and Xanthium strumarium. Most warm- and cool-season rangeland and pasture grasses are tolerant of aminopyralid applications at proposed rates. Research continues to determine the efficacy of aminopyralid on other key invasive weeds and on the role of aminopyralid in facilitating plant community improvement in land management programs.
