When to Use:
- Use anytime weeds are actively growing. Most treated weeds usually show initial symptoms in 2–4 days and complete kill in 1 to 2 weeks. Larger more established weeds may take up to 4 weeks for complete kill. For best results, apply on a warm sunny day when daytime temperature is above 60°F and no rainfall is forecast for 24 hours. Warm, sunny weather will speed up weed control. Apply only when air is calm. Reapply if it rains within 2 hours after application. Rainfall or watering 2 hours after application will not wash away effectiveness. Hard-to-control weeds (such as bermudagrass) may require a repeat application if they regrow. NOT recommended for spot weed control in lawns since Concentrate Grass and Weed Killer 41% Glyphosate kills all green plants, including lawn grass.
Where to Use:
General Weed Control:
- Use along fences, paths, patios, sidewalks and driveways, around trees, shrubs, and ornamental plantings and flower beds, around buildings, and in brick and gravel walkways. Use to trim and edge landscape areas. DO NOT use for spot weed control in lawns since Concentrate Grass and Weed Killer 41% Glyphosate kills all green plants, including lawn grass.
- Use on actively growing weeds in and around flower beds, ornamental trees, fruit and nut trees, grapevines, shrubs, fences, driveways and walkways. Spray when air is calm. Make sure Concentrate Grass and Weed Killer 41% Glyphosate does not contact the leaves, green stems, or exposed roots of plants you don't want to kill. If necessary, use cardboard or plastic to shield plants. Concentrate Grass and Weed Killer 41% Glyphosate will not move in or on the soil to untreated plants. If Concentrate Grass and Weed Killer 41% Glyphosate is used to control weeds around fruit or nut trees or grapevines, allow 21 days before eating the fruit or nuts.

- Under dry conditions, water lawn every other day for a week before using this product.
- Do not mow for 7 days before or after treatment.
- After 7 days, prepare the soil for planting by raking or rototilling the lawn. Rake up and remove loosened thatch or debris.
- Mix in starter fertilizer and other amendments, if needed. Level the soil.
- Apply seed according to directions on seed package, or install sod.
- Grass seed must have a good contact with soil to germinate and grow.
- Keep area moist for 2 weeks to establish new lawn, then water as needed.
- Use when brush is green and growing. If plants are taller than 5 feet, cut back and spray regrowth. Brush sprayed in the fall may not be fully controlled until the following season. Hard-to-control species such as Blackberry, Kudzu, or Poison Oak may require a second application.
Stumps can be treated to prevent regrowth. For best results, treat when the vegetation is actively growing and within 5 minutes of being cut down.
- Cut the stump close to the soil surface.
- Drive 4-5 nail holes into the stump.
- Flood the stump with undiluted product.

To Kill Vines:
- If vine is growing up a pole, fences, or mature tree trunk, cut vine to a height of 3 to 4 feet and spray to thoroughly cover remaining vine.
