*annual or perennial

This pesticide is toxic to aquatic invertebrates. To protect the environment, do not allow pesticide to enter or run off into storm drains, drainage ditches, gutters or surface waters. Applying this product in calm weather when rain is not predicted for the next 24 hours will help to ensure that wind or rain does not blow or wash pesticide off the treatment area.

Do not apply this product in a way that will contact any person or pet, either directly or through drift. Keep people and pets out of the area during application.


  • Clothing and protective equipment exposed to this product should be washed in detergent and hot water. Such items should be kept and washed separately from other laundry.

  • Completely wet the leaves of the target vegetation. 
  • Sprayed plants begin yellowing and wilting in as little as three hours, with complete kill, including the roots, in one to two weeks.
  • Thoroughly cover treated areas to prevent new weeds and grasses from growing.
  • Provides season-long protection
  • Protect desirable plants with a piece of plastic or cardboard.
  • If desirable plants are accidentally sprayed, wash plants with water immediately. 
  • For best results, apply during warm, sunny weather (above 60°F) when weeds are actively growing and no rain is forecast for 24 hours. Rainfall or watering 15 minutes after application will not wash away effectiveness.
  • To avoid drift to desirable plants, apply when the air is calm.
  • Do not mow, cut or otherwise disturb treated vegetation, weeds or plants for at least seven days following application.
  • Do not use on or around edible feed or food crops.
  • Do not use in areas that are to be planted or seeded within three months.
  • Do not use around newly planted trees, shrubs or flowers.
  • Do not make more than two applications per year to any given area.

Not recommended for spot weed treatment in established lawns since lawn grasses will also be killed.
