Spectracide® Weed & Grass Killer2 (Ready-to-Use)

This product is a non-selective herbicide that will kill any vegetation contacted. It enters plants through the leaves and moves down to the roots. This will ensure that the entire plant is eliminated. Avoid direct spray or drift onto desirable plants, lawn grasses, shrubs, and trees. Protect desirable plants and vegetation with a piece of plastic or cardboard. If desirable plants are accidentally sprayed, wash plants with water immediately. This product has no soil activity and thus will not affect nearby untreated plants.
  • Visible results as fast as 3 hours
  • Kills the root
  • Use around trees and shrubs, in flower beds and on patios and walkways
  • Replant flowers, trees and shrubs the same weekend

1 Gallon container

  1. Shake well before each use.

  4. Firmly press black hose tip into opening in cap until it snaps into place.
  5. Hold sprayer below the level of the container and prime by pumping trigger several times until product is dispensed.

  1. To store, turn sprayer nozzle off.
  2. DO NOT disconnect hose.
  3. Return sprayer to its slot. Hose can be pushed back into sprayer handle.

32 fl oz container

  1. Shake well before each use.
  2. Adjust nozzle to narrow fan spray to prevent excessive wetting and waste of product. Spray just enough to cover area to be treated.
  3. Avoid contamination of food, feedstuffs and domestic water supplies. All food-processing surfaces and utensils should be covered during treatment or thoroughly washed before use. Remove pets and birds, and cover fish aquariums before spraying.

  • Completely wet the leaves of the target vegetation. Do not overspray.
  • Sprayed plants begin yellowing and wilting in about 24 hours, with complete kill, including the roots, in one to two weeks.
  • Protect desirable plants with a piece of plastic or cardboard.
  • If desirable plants are accidentally sprayed, wash plants with water immediately.
  • 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.
  • 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.

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

  • All ornamental flowers, trees and shrubs may be planted one day after application.
  • Determine size of area to be treated — measure length and width in feet, then  multiply to determine coverage area in square feet (length x width).
  • Use Spectracide® Weed & Grass Killer2 to kill the old lawn and existing weeds and grasses.
  • For best results, apply in spring or fall, when daytime temperatures are at least 60°F.
  • Under dry conditions, water lawn every other day for a week before applying Spectracide Weed & Grass Killer2.
  • Do not mow for seven days before or after treatment.
  • One gallon treats 300 sq ft.
  • Wait seven days after last application to rake, till or replant with seed or sod.
  • Rake up and remove loosened thatch or debris.
  • Mix in starter fertilizer and soil amendments, if needed. Level the soil.
  • Apply seed according to directions on seed package, or install sod. Grass seed must have good contact with soil to germinate and grow.
  • Keep area moist for two weeks to establish new lawn, then water as needed.
Refill only with Spectracide® Weed & Grass Killer Concentrate2. Remove cap. Carefully measure and mix 7 fl oz (14 Tbsp) in 1 gal of water. Replace and tightly close cap. Wipe off any spilled product.
