| Abstract/Contents: | "RP-EXP 31130A (isoxaflutole) was applied in 1996 to perennial ryegrass turf infested with "Midiron" bermudagrass, as the second season of a two year study to determine the control or suppression capability of this compound on bermudagrass in perennial ryegrass turf. Mild suppression was achieved at the rate of 0.18 lb. AI/A, while moderate control was achieved at the 0.36 lb. AI.A rate. Double applications at the low rate did not favor suppression for very long, over the single application at the same rate (0.18 lb. AI/A). Reversal of rates at the second application did not enhance overall suppression. The 0.36/0.36 lb.AI/A treatment provided the highest level suppression, noting that the main effect of `chemical treatment' was not significant for suppression during year two of this test. Leaf bleaching and the percent of the bermudagrass foliage affected was rate dependent. All bermudagrass in the test increased considerably among treated plots (since spring 1995 when all bermudagrass was 80 square cm of plot surface area), to astronomically for the checks by the close of the test in year two (1996). Multiple applications appear warranted at the 0.36 lb. AI/A rate every 21 days to promote a high level of suppression of bermudagrass in perennial ryegrass turf under desert conditions." |
