Suggested Weed Control Calendar for Bermudagrass Sports Fields


Trimec/2,4-D if needed for broadleaves


Non-overseeded: apply atrazine (dormant bermudagrass) @ 1.5 qt/acre or simazine @ 1.5 qt/acre + Trimec or 2,4-D

Optional – for preemergence control of crabgrass and goosegrass apply oxadiazon - trade name Ronstar


Broadleaf weed control if necessary using Trimec/2,4-D

In 2,4-D restricted zones and non-overseeded bermudagrass apply metsulfuron (Manor/Blade) for most broadleaves


Monitor field for summer weed emergence


For dallisgrass, and crabgrass control apply MSMA and repeat in 7 to 10 days

Trimec or 2,4-D for broadleaves

In 2,4-D restricted zones and non-overseeded turf apply metsulfuron (Manor/Blade) for most broadleaves


MSMA for grasses + Sedgehammer, Certainty, or Monument for nutsedges repeat MSMA in 10 days.

MSMA + Sencor for goosegrass and dallisgrass repeat in 10 days

For Virginia buttonweed control apply multiple applications of Trimec/2,4-D.

In 2,4-D restricted zones apply metsulfuron (Manor/Blade) for most broadleaves


MSMA as needed for crabgrass or MSMA + Sencor for goosegrass repeat in 10 days. 2,4-D or metsulfuron for broadleaves.


MSMA as needed for crabgrass

Add nutsedge killer if necessary.








Non-overseeded bermudagrass: Apply simazine @ 1.5 qt/A after last home game on football fields for annual bluegrass and winter broadleaf control + 2,4-D


Common Herbicides Used for Athletic Turfgrass Weed Management

  • Atrazine – similar to simazine – apply in dormant bermudagrass usually in January or February after simazine in November – one of the best herbicides for winter weed management.

  • Glyphosate (Roundup and generics) – non-selective herbicide. Rate = 2.6 oz/gallon.

  • Metsulfuron (Manor/Blade) – Excellent broadleaf herbicide that also controls bahiagrass. Herbicide is a very effective alternative to 2,4-D containing products.

  • MSMA – good crabgrass and dallisgrass control – repeat application in 7 to 10 days. Add Sencor for goosegrass.

  • Nutsedge Killers (coco, nutgrass) – halosulfuron (Sedgehammer), sulfosulfuron (Certainty), trifloxysulfuron (Monument) – all are very effective and can be tank-mixed with MSMA.

  • Simazine – most often used after the last home game in football in November – provides preemergence and early postemergence annual bluegrass (Poa) and winter broadleaf weed control.

  • Sencor – often added to MSMA to increase effectiveness on goosegrass. Consult label for rates.

  • 2,4-D – economical herbicide that provides adequate control of most broadleaves. Herbicide is not effective on white clover. Observe restriction periods in cotton production areas of the state.

  • Trimec – contains three broadleaf herbicides 2,4-D, mecoprop, and dicamba. Usually more effective than 2,4-D alone and better on clovers, thistles etc. Observe 2,4-D restrictions for cotton areas.
