Tribute Total (1 oz/A) + Harrell’s Nonionic Penetrant Plus (1 qt/100 gal).
2 Apply Sapphire at 24 fl oz/A + Harrell’s Nonionic Penetrant Plus (0.25% v/v). Treatments should be applied when removal of ryegrass is desired to accelerate the transition to the existing perennial bermudagrass. Applications on 14-21 day intervals. Consult label for application restrictions. 3 Kerb SC T&O (1.25 to 3.5 pint/A). The dosage rate required is dependent on the growth stage of annual bluegrass at time of application and the use site. For application onto golf course greens, do not apply more than 2.5 pt/A per application and ensure there is no overlap of the spray or turfgrass injury may occur. For most effective Poa annua control, particularly on golf course greens, make applications from early fall through December at reduced rates. 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.

Tribute Total (1 oz/A) + Harrell’s Nonionic Penetrant Plus (0.25% v/v).
Monument 75 WG (0.35 – 0.45 oz/A) + Harrell’s Nonionic Penetrant Plus (0.25 – 0.5% v/v).
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, 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 (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. To maximize control of mature weeds, make applications when the daily temperature is above 70 degrees. Tank mixing with Harrell’s Methylated Seed Oil (up to 1% v/v) may improve efficacy while increasing the chance of phytotoxicity under some conditions. 2 Monument 75 WG (0.1 to 0.35 oz/A) + Harrell’s Non-Ionic Penetrant Plus (0.25 – 0.5% v/v). The lowest rate allows for a more gradual transition, however the turf may be temporarily discolored. If applied to dormant bermudagrass, some delay in green-up may be observed. A activly growing bermudagrass base should be present before using this program to facilitate and optimal transition. 17 MSMA (1.8 pt/acre) + Harrell’s Nonionic Penetrant Plus (0.25% v/v). Tank-mixing Sencor 25DG at 0.33 lb/acre with MSMA increases control as well as bermudagrass phytotoxicity potential. Repeat applications 7 days apart are needed for control. For golf course application only spot treatments (100 square feet maximum per spot) are allowed. Spot treatment must not exceed 25% of total golf course acerage per year. Not for use in Florida. 2 Monument 75WG (0.53 oz/A) + Harrell’s Nonionic Penetrant Plus (0.25 – 0.5% v/v). Sequential applications may be required for full control. 1 Manuscript 9.6 fl oz per 10,000 sq. ft. + Adigor at 0.5% v/v followed by Manuscript 9.6 fl oz per 10,000 sq. ft. + Adigor at 0.5% v/v + Monument 75WG 0.53 oz/A. Do not apply more than 19.2 fl oz of Manuscript per acre per calendar year. 17 MSMA (1.8 pt/acre) + Harrell’s Nonionic Penetrant Plus (0.25% v/v). For golf course application only spot treatments (100 square feet maximum per spot) are allowed. Spot treatment must not exceed 25% of total golf course acerage per year. Not for use in Florida.

2 Revolver 0.19L (17.4 – 35.2 fl oz/A). Revolver rate and temperature will influence the speed of removal. Higher labeled rates and air temperatures will result in quicker removal.
