Product Overview

Spectracide Weed and Grass Killer With Extended Control is a non-selective herbicide that is ready-to-use and fast-acting. It kills all types of grasses and roots, targeting the roots to prevent regrowth. It works by seeping through the leaves then quickly moving down to the roots. This action ensures that the entire plant is killed leaving no chance for regrowth. It also produces a protective barrier which prevents weeds and grasses from appearing for up to 90 days. It works quicker compared with competitor brands, it is rainproof within 15 minutes while visible results start to show just 3 hours after initial application. This particular product comes in a 1-gallon jug.

  • 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.

  • 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.
