Sulfentrazone was applied to perennial ryegrass turf as single applications at 0.125, 0.250 and 0.375 lb. AI/A, and split application combinations of 0.125/0.125, 0.250/0.250 and 0.375/0.125 AI/A. Respective treatments were applied on June 28 and July 31, 1996. Sulfentrazone caused a decrease in turfgrass color, which was most noticeable at the 0.375 lb. AI/A rate. Decreases in color were generally dependent on application rate. Sulfentrazone caused a slight "pocking" of the turf, which resulted from leaf twisting/cupping. This injury was most evident at seven days after the first application. There was no foliar burning or uneven discoloration however. The turf exhibited a lesser amount of discoloration and injury following the second (split) application.Series/Report no.
