Abstract/Contents:Presents a study that "evaluated the effects of several postemergence herbicides on newly-established bermudagrass seedlings. In addition, a second technique was evalauted which used activated charcoal to protect bermudagrass seed rows from preemergence herbicides." Details methods and materials used in the study, stating that "prior to planting, both plot areas were fumigated with methyl bromide (67%) and chloropicrin (33%) at a rate of 392 lb [pounds]/acre to ensure a weed-free site. Since the weed control effectiveness of the herbicides tested was previously established, it was easier to rate herbicide injury without interference from weeds. 'Princess' seeded bermudagrass was chosen for both studies because of its high quality and commercial availability." Lists herbicides evaluated in the study, including MSMA, metsulfuron, diclofop, clopyralid, dicamba, 2,4-D Amine, qunclorac, prodiamine, oxadiazon, and diuron. Reports that "time after emergence for herbicide applications had no effect on the injury caused by the various postemergence herbicides...All postemergence herbicides caused some degree of injury on newly seeded 'Princess'...Diclofop, metsulfuron, and 2,4-D produced the highest level of injury." Also reports that "activated charcoal successfully protected seeds from preemergence herbicides...while those not treated with charcoal failed to germinate...In addition, there were no significant differences between control, charcoal-banded treatments and control, non-charcoal banded plots."
