dc.description.abstractEXP31130A and EXP31598A were applied as repeat applications on June 5 and July 23, 1997 to perennial ryegrass maintained at 3.0 inches. Application rates were 0.18 and 0.36 lbs. AI/A (31130A) and 7.0 and 14.0 fl. oz/prod/A (31598A). Each treatment was applied with and without Sequestrene 338 iron chelate, at the rate of 0.1 oz/m². Untreated and iron-only controls were included in the test. Ryegrass was generally unaffected by either compound, under the conditions of this test. Inclusion of iron (in the tank mix) was more beneficial for EXP31598A, than for EXP31130A. Untreated controls generally had lower performance scores, than did turf which received either herbicide compound. Treatment effects for overall turfgrass quality were significant only on three of ten evaluation dates, and on one of ten evaluation dates for turfgrass color. In general both compounds appear safe to use on high cut perennial ryegrass turf under summer conditions in a desert environment.
