glyphosate herbicide

Glyphosate products come as concentrates that you mix with water and as ready-to-use (RTU) spray products. Some are sold in pourable refill jugs for reusing a sprayer or refilling RTU containers.

Timing varies by product. Some labels permit planting within about 1 to 30 days after application; products that include a preventer or extended-action ingredient may advise waiting roughly 4 months before planting sensitive ornamentals. Always follow the specific label instructions for the product you used.

Rainfast times vary by formulation: some products state they are rainproof in as little as 30 minutes, while certain lawn-focused formulas list a 3-hour rainfast period. Check the product label for the exact rainfast time.

Coverage varies widely by product size and concentration. Examples from product details include about 56 sq ft for a 24 fl oz trigger bottle, roughly 300 sq ft for a 1‑gallon RTU, 800–1,500 sq ft from a 16 oz concentrate mixed as directed, and up to about 10,000 sq ft for larger pourable refill jugs. See the product label for exact coverage and mix rates.

Recommendations vary by product. Examples include applying in warm, sunny weather above about 60°F, and for lawn-focused products applying in spring or fall when daytime temperatures are roughly 45–90°F. Follow the label for the specific product and local conditions.

Some formulations that include a preventer report up to about 4 months of prevention against new weeds; certain lawn-ready products list up to 3 months of weed control. Check the product label for the stated duration.

The lawn-targeted product is labeled for several cool- and warm-season grasses, including Kentucky bluegrass, perennial ryegrass, tall, red, and fine fescues, and zoysiagrass (as listed on the product label).

Concentrates are labeled “mix with water” and include mixing directions (for example, a 16 oz concentrate can make multiple gallons when mixed as directed). Some refill bottles advertise “no mixing, no measuring” and are designed to refill or reuse a one-handed sprayer.

Product details advise keeping people and pets out of treated areas and away from treated plants until sprays have fully dried. Follow the specific product label for any additional access or re-entry restrictions.
