Applications of sulfentrazone were applied to 2.75" mowed tall fescue under hot-humid desert conditions to assess post application response. A uniform decrease in color occurred shortly after application at the 0.375 lb. AI/A rate. The effect was short lived and tended to be minimal in split application treatments. Leaf cupping/twisting was exacerbated from applications of sulfentrazone, especially at the 0.375 lb. AI/A rate. At 0.125 and 0.250 lb. AI/ rates, the leaf cupping was much less noticeable. Percent plot showing the leaf cupping symptoms was also rate dependent and generally ranked with degree of effect. Leaf cupping dissipated rapidly after 14 days after treatment. Color changes were minor, while leaf cupping was the more noticeable symptom response on tall fescue from applications of sulfentrazone.
