Winter/Spring Recommendations Bayer offers two premium preemergence herbicides for use in warm-season turf. The first, Ronstar ® , remains a standard for weed control, while Specticle ® FLO offers a novel mode of action and a different class of chemistry than Ronstar. Both products provide outstanding control and have unique features and benefits that are outlined below: Specticle ® FLO // Broad-spectrum control
Ronstar ® // Excellent control of goosegrass // Controls weeds via shoot uptake in the presence of sunlight (protox inhibitor) // No effect on turf root systems // For sites with winterkill concerns, use instead of Specticle FLO for first PRE application // Choose between Ronstar FLO and Ronstar on Fertilizer Application Best Management Practices: // Do not apply to saturated soils // Activate with light irrigation (0.1-0.125”) or rainfall soon after application // Delay application when major rain events are predicted soon after application // Cool-season turf options: only Ronstar on Fertilizer
// Excellent control of Poa annua , goosegrass, doveweed and annual kyllinga and sedges // Up to 6 months of residual control // Low amount of ai/A // Compatible with postemergence herbicides // Great complement to Ronstar Application Best Management Practices: // Apply when the soil is as dry as possible – do not apply to saturated soils // Activate with light irrigation (0.1-0.125”) or rainfall soon after application // Delay application when major rain events are predicted soon after application // Avoid application to cool-season turf
