Abstract/Contents:"Annual grass weeds can inhibit establishment of perennial forage grasses. Field experiments were conducted in 1985 and 1986 to determine the effectiveness of fenoxaprop for annual grass weed control in seedling 'Climax' timothy (Phleum pratense L.) and 'Penlate' orchardgrass (Dactylis glomerata L.), each growing alone or ina mixture with 'Oneida' alfalfa (Medicago sativa L.). The purpose was to determine the stage of early development that the perennial grasses were most tolerant of fenoxaprop, concomitant with the most appropriate application rate of the herbicide. Fenoxaprop was applied to both grass and grass-legume mixtures at 0, 0.08, 0.12, 0.16 kg./ha in 260 1/ha of water at 40 kPa pressure. Stage growth at time of treatment follows: 1st 2nd 3rd 1985 timothy 3 leaf 4 leaf 4 to 5 leaf orchardgrass 3 leaf 4 to 5 leaf 6 leaf 1986 timothy 2 to 3 leaf 4 leaf 5 leaf orchardgrass 2 to 3 leaf 4 to 5 leaf 6 leaf For control of broadleaf weeds, all grass plots received a broadcast application of 2,4-D at 0.55 kg/ha and the alfalfa-grass plots received 0.8 kg/ha 2,4-DB in 1986 and 0.8 kg/ha bentazon in 1985. Forage and composition were determined the year of planting and the year following. Fenoxaprop, at all doses applied, controlled the annual grasses satisfactorily in both timothy and orchardgrass alone or with alfalfa. The time for visible effect on the annual grass species was rate dependent, with the largest quantity of fenoxyprop (0.16 kg/ha) showing the most rapid and lasting effect. The lower rates of fenoxyprop (0.08 and 0.12 kg/ha) gave adequate control albeit with not as rapid effect. Seedling orchardgrass tolerated fenoxyprop at all rates applied and and stages of growth to the sixth true leaf, both when growing alone or with alfalfa. Seedling timothy compared to orchardgrass was more susceptible to fenoxyprop but still exhibited considerable tolerance. Fenoxyprop applied at 0.08 kg/ha at the 2 to 3 leaf stage was tolerated by timothy and it controlled the grass weeds sufficiently. The o.16 kg/ha rate of fenoxyprop damaged seedling timothy but had no effect on timothy yields the year following planting. In summary, fenoxaprop is a viable herbicide for selective control of annual grasses in new plantings of timothy or orchardgrass alone or in mixture with alfalfa."
