| Abstract/Contents: | Field studies were conducted from 1977 to 1981 on the control of dandelions (Taraxacum officinale L.) and other broadleaved weeds in creeping red fescue (Festuca rubra var. geniuna L.). Creeping red fescue was established either alone or with a companion crop of barley (Hordeum vulgare L.) or rapeseed (Brassica campestris L.). The barley was harvested in early August for fodder or in early September for grain. Several herbicide treatments were applied to each crop situation. Bromoxynil plus MCPA applied at 0.28 + 0.28 kg a.i./ha when the creeping red fescue was in the three-leaf stage (and 1-2 mo old) controlled 75% or more of the annual weeds during the year of seeding. This herbicide combination also provided substantial control of dandelions and other weeds during the year following seeding. A second herbicide treatment of dicamba plus 2,4-D at 0.28 + 0.56 kg a.i./ha in May of the year following seeding provided an improvement in the control of dandelions and other weeds over the single application of bromoxynil plus MCPA in some but not all seedings. The use of rapeseed as a companion crop without any herbicide treatments did not provide consistent weed control. Seed yields during the second production year were increased by 25% or more from the use of herbicide treatments when creeping red fescue was seeded alone or with barley harvested for fodder. First production year seed yields were not increased by any of the herbicide treatments. Similarily, first and second production year seed yields were not increased by any of the herbicide treatments when creeping red fescue was seeded with barley harvested for grain. Harvesting barley as fodder rather than grain produced marginally higher first production year creeping red fescue seed yields but had no effect on second production year seed yields. |
