Effect of Iron sulfate and Trimmit on turf quality and poa invasion
View Larger
In this 2 year study, iron sulfate (FeS) and Trimmit (paclobutrazole) were evaluated for their impact on poa control and on turf quality. The best poa control and the highest turf quality resulted from FeS combined with Trimmit at FeS rates of 0.5 and 1.0 lbs. For more information, see this report. Data from N. Ream et. al., Virginia Agricultural Experiment Station.
