2 Revolver 0.19L (4.4 – 17.4 fl oz/A). Revolver rate and temperature will influence the speed of removal. Higher labeled rates and air temperatures will result in quicker removal. For best results to control mature weeds, make applications when the daily temperature is above 70 degrees. Including Harrell’s Methylated Seed Oil (up to 1% v/v) may improve efficacy while increasing the chance of phytotoxicity under some conditions. Not for use in California. 27 Tenacity (5 fl oz/A) + Harrell’s Nonionic Penetrant Plus (0.25% v/v). Apply Tenacity in at least 30 gallons of water per acre at two to three-week intervals for up to three applications. Bentgrass control may be more effective in the late summer/early fall just prior to onset of renewed bentgrass growth, than spring/early summer applications. 4 Make 2 sequential applications of Harrell's ProtectMAX Quinclorac (44 fl oz/A) + Harrell’s Methylated Seed Oil (1.5 pt/A) followed by an additional sequential application of HPM Quinclorac (39 fl oz/A) + MSO (1.5 pt/A) on 14-day to 21-day intervals. 2 Katana (0.5 to 1.5 oz/A) + Harrell’s Nonionic Penetrant Plus (0.25% v/v). Applications during spring transition do not negatively impact bermudagrass greenup. Katana herbicide shows a slight rate response with control occurring within 3-4 weeks after application with the highest labeled rate giving better and faster control. Therefore, bermudagrass or zoysiagrass turf needs to be at 50 to 60% greenup at the time of application to facilitate an optimal transition. 2 Revolver 0.19L (8.8 – 17.4 fl oz/A). Revolver rate and temperature will influence the speed of removal. Higher labeled rates and air temperatures will result in quicker removal. For best results to control mature weeds, make applications when the daily temperature is above 70 degrees. Including Harrell’s Methylated Seed Oil (up to 1% v/v) may improve efficacy while increasing the chance of phytotoxicity under some conditions.

2 Revolver 0.19L (4.4 – 17.4 fl oz/A). Revolver rate and temperature will influence the speed of removal. Higher labeled rates and air temperatures will result in quicker removal. For best results to control mature weeds, make applications when the daily temperature is above 70 degrees. Including Harrell’s Methylated Seed Oil (up to 1% v/v) may improve efficacy while increasing the chance of phytotoxicity under some conditions. Not for use in California. 2 Katana (2.25 to 3 oz/A) + Harrell’s Nonionic Penetrant Plus (0.25% v/v). Applications for spring transition do not negatively impact bermudagrass greenup. Katana herbicide shows a slight rate response with control occurring within 3-4 weeks after application with the highest labeled rate giving better and faster control. Therefore, the bermudagrass or zoysiagrass turf needs to be at 50 to 60% greenup at the time of application to facilitate and optimal spring transition.
