| Abstract/Contents: | "RP EXP31130A herbicide was applied on AUgust 3 and September 4, 1995, on perennial ryegrass turf which was infested with uniform amounts of bermudagrass. Two rates were applied, 0.18 and 0.36 lb. AI/A, as single or tandem (sequential) applications. EXP31130A caused leaf bleaching (chlorophyll loss) visible at 5DAT, which was also rate dependent and showed maximum expression at 10-14 days after treatment. The bermudagrass did recover somewhat by 24 days after the first treatment. Regrowth of the turf was weak in color, but it did eventually recover. Sequential applications having at least one rate at 0.36 lb. AI/A, caused the greatest changes in color, but not necessarily for leaf bleaching. Based on re-greening of treated bermudagrass after leaf bleaching, decreased time intervals appear warranted. Bermudagrass suppression was achieved from two treatments during the late summer of 1995. Suppression ranged from 12% to 42% based on rates. No damage was visually realized on the host ryegrass turf. Final determination of potential latent necrotic bermuda can be determined during the spring of 1996. The apparent selectivity between ryegrass and bermudagrass may be beneficial for golf course managers." |
