What It Controls

Before using any product, it’s a good idea to understand exactly what that product aims to do.

• Nutsedge (nutgrass): Both purple and yellow varieties.
• Kyllinga: A small sedge that looks like a nutsedge.
• Poa annua (annual bluegrass): A grassy weed that pops up in thin spots.
• Over 50 other broadleaf weeds: Including dandelions, chickweed, knotweed, plantain, spurge, and more.

How It Works

Understanding the process can help users get the best outcome.

• The formula consists of sulfentrazone 1.4%, which is a contact herbicide and stops weed growth on contact at the leaf level.
• It works on the foliage of the plant. When the leaves take up the chemical, the weed’s growth is stunted. Subsequently, the plants turn yellow and die.
• Grass types are naturally tolerant of sulfentrazone, so it only affects unwanted plants.

When to Apply

Timing is critical for lawn health and for efficacy.

• Apply to weeds that are green, healthy and less than 3 inches tall. This ensures a good application of herbicide uptake.
• For new seed or sod, don’t apply until lawn has been mowed 3 times or is 4-6 weeks old.
• Schedule application of this homemade weed killer on a day with no wind to avoid drift onto flowers or vegetables. Make sure no rain is in the forecast for at least two hours after applying.

Step-by-Step Application Guide

Users benefit from a clear routine for product application.

1. Attach the spray head to a garden hose and turn on the water.
2. Turn the thumb switch on the bottle to the “On” position.
3. Walk slowly and at a constant pace, holding the nozzle no closer to the weed than 12-18 inches. Make sure to completely coat the foliage and do not saturate.
4. Do not apply to flowers, vegetables, shrubs or ornamental beds. Shield these areas if needed.
5. Do not let children or pets on the treated areas until completely dry (approximately two hours).

Safety and Precautions

Label directions are there to keep people, pets and the environment safe.

• Keep Out of Reach: Always keep the product sealed in a safe storage place when not in use, and keep it out of reach of children and pets.
• Protect Non-Target Plants: Prevent spray drift on desirable plants. Heavy rain can knock over flowers and can also cause damage to some vegetables.
• Wear Protective Gear: Although it is low-toxicity once dry, wearing gloves and eye protection during application is best practice.
• Observe Re-Entry Time: Allow treated grass to dry fully. Then you can resume your regular routine.
