Abstract/Contents:"RP EXP31130A herbicide was applied on two occasions at 0.18 + 0.36 lbs. AI/A on `Penncross' creeping bentgrass turf during the summer of 1995. Creeping bentgrass quickly developed the symptoms of bleaching (white leaves-loss of chlorophyll). From the initial application, the degree and extent of bleaching was rate dependent, with maximum expression at 9-10 days after treatment (DAT). After a second treatment of these rate combinations one month later, bleaching was generally a linear and cumulative response. After bleaching occurred, the turf turned straw (necrotic in color), but generally showed regrowth, except for some plots at the high (0.36 lb. AI/A) rate. Sequential treatments caused overall color loss of tur as well at both 5DAT/2 and 14DAT/2. Turfgrass color was restored 7-8 weeks after treatment from single initial applications at either rate, however, the turf did not tolerate sequential applications, and was visibly damaged for 30 days from the sequential treatment. At 25DAT/2 loss of turf occurred on treatments which received at least one application at the 0.36 lb. AI/A rate, and as well as from any sequential combination. The tolerance of `Penncross' creeping bentgrass is very low to RP EXP31130A."
