1 Segment II (1.5 pt/acre) + Harrell’s Crop Oil Concentrate (2 pt/A) or Harrell’s Methylated Seed Oil (1.5 pt/A). Do not apply more than 3.0 pt/A Segment II per season. 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. 1 Segment II (1.5 pt/acre) + Harrell’s Crop Oil Concentrate (2 pt/A) or Harrell’s Methylated Seed Oil (1.5 pt/A). Do not apply more than 3.0 pt/A Segmetn II per season. 3 Kerb SC T&O (1.25 – 2.5 pt/A). Apply Kerb to warm season grasses at 50% greenup for ryegrass removal. Avoid spraying on hill sides, fairways, or approaches that may drain onto bentgrass greens or to areas overseeded with sensitive cool season grasses. 1 Manuscript 16.4 oz/A. Add Adigor adjuvant or Harrell’s Methylated Seed Oil at 0.5% v/v. For best results, apply to actively growing perennial ryegrass before emergence of 3rd tiller. 2 Katana (0.5 to 1.5 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 for optimal spring transition.

5 Princep Liquid (1 qt/A). Apply after October 1 for Poa annua control. Refer to product label for tips to minimize desirable turf injury. 14 Sureguard SC (8 – 12 fl oz/A) + Harrell’s Nonionic Penetrant Plus (1 qt/100 gal). Apply only to fully dormant bermudagrass. 10 Cheetah Pro (56 – 82 fl oz/A) OR Finale (3-6 qt/A). Apply only to fully dormant bermudagrass. Avoid high volume and spot applications where spray volume exceeds 80 gallons per acre or injury or delayed green-up may occur. 8 Prograss 1.5 EC (1/2 to 1-1/3 gal/A). Treat young (1 to 5 leaf stage) weeds in fall. Will not adequately control mature plants or perennial biotypes. Multiple applications spaced 3-4 weeks apart may be necessary. Application during bermudagrass spring greenup will injure bermudagrass.
