Abstract: The authors compared fall (October), spring (April), and late summer (August) applications of glyphosate and paraquat at different rates in Missouri. The authors recommend spring and late summer applications of glyphosate at 1.68 and 2.52 kg ai/ha because they reduced tall fescue cover to less than 15% 30-50 DAT (days after treatment). Fall applications of glyphosate at 0.42 and 0.84 kg ai/ha resulted in 56 and 42% tall fescue cover respectively. April and August were identified as the best times to spray tall fescue. Overall, herbicide applications were not as successful as reported by studies previously mentioned. The authors noted tall fescue grows through fall in the South more so than in the Midwest. The increase in active growth as well as greater rainfall and average daily temperatures may explain the increased effectiveness of fall applied herbicides on tall fescue in the South
