Follow all label directions. 1Use Ronstar FLO 2.5 lb. ai./A rate in northern part of transition zone and 3 lb. ai./A rate in southern part of transition zone. New labeling on Ronstar FLO makes it a restricted use
pesticide and limits application area. Check your specific label prior to application. 2Do not apply if turf injury is present and assess turf quality before each application. 3Spread rate should be minimum of 250 lbs. of fertilizer per acre for regular granule size and 200 lbs. per acre for mini granule size. 4If winterkill is not a concern, other options include dithiopyr or prodiamine. 5Avoid applications of Echelon to zoysiagrass during periods of transition. For improved efficacy apply an additional 12 fl. oz./A 60-90 days later.
