Product Information

Segment Herbicide (Vantage)- 1 Gallon

Segment Herbicide has been replaced with Segment II with a higher percentage of Sethoxdim.

Segment Herbicide, with Sethoxydim 13.0% targets weeds without harming crops or ornamentals accidentally. It controls weed problems in annual bluegrass, centipedegrass, tall fescue (established), and fine fescue (established). Sethoxydim has had a long history of success in the post-emerge grass control as tough on perennial and annual grass weeds. Segment is a selective, post-emergent, broad spectrum herbicide. This herbicide is an "over-the-top" herbicide that may be used on more than 350 species of ornamentals and is rainfast in one hour. Segment Herbicide does not control broadleaf weeds or sedges.

Segment's benefits include not causing injury to listed ornamental plants at any stage of growth. It can be applied directly to trees or shrubs even in seedling stages. It may be applied on any non-grass species without issue. Segment is very compatible with other herbicides as a tank mix for flexibility. See label for tank mix suggestions.

Segment's Mode of Action

Segment's active ingredient, Sethoxydim is introduced rapidly to the plant through its foliage. It travels(translocates) throughout the plant. The effects range from slowing/stopping growth to foliage leaf tip burn and foliage burnback. Depending on environmental conditions, symptoms may be observed within 3 weeks.

Keys To Success

  • Apply Segment when grasses are actively growing and free of stress
  • Use a standard high-pressure flat fan or hollow cone nozzle for application.
  • Irrigate prior to application to enhance uptake.
  • Spray the area thoroughly enough to wet the target grass.
  • Add Nitrogen Source (AMS) for optimum performance.

We also carry Sethoxydim 13.0%, Bonide's Grass Beater Over The Top Grass Killer. It is packaged in a smaller 8 oz size.

More Instructions
  • Coverage: Apply Segment uniformly and completely to the foliage of grasses on a spray-to-wet basis. Dense leaf canopies shelter smaller grassy weeds and can prevent adequate spray coverage.
  •  DO NOT spray to the point of runoff.
  • Cultivation/Mowing: If cultivation is an option, DO NOT cultivate during the time between 5 days before and 7 days after applying Segment. Cultivating 7 to 14 days after treatment may help provide season-long control of perennial grasses. Centipedegrass and fine fescue areas should not be mowed within 7 days before or after applying Segment. Increased control has been observed when mowing is delayed until 14 days after application. Grass weeds that have been mowed or have regrown from mowed stubble may be controlled poorly. Repeat application if new germination or regrowth occurs.
  • Stress: DO NOT apply to grasses or crops under stress, such as stress due to lack of moisture, hail damage, flooding, herbicide injury, mechanical injury, or widely fluctuating temperatures, as unsatisfactory control will probably result.
  • DO NOT apply to crops that show injury (leaf phytotoxicity or plant stunting) produced by any other prior herbicide applications because this injury may be enhanced or prolonged. Note: Applications to tall fescue will result in discoloration and growth suppression. If reduced turf quality is not acceptable, applications should not be made to tall fescue.
