weed killer concentrate

Most weed killer concentrates are mixed with water and applied with a tank sprayer, hose‑end sprayer, or pump‑style sprayer. Some products come in pourable jugs or as ready‑to‑spray hose‑end solutions.

Pre‑emergent concentrates prevent weeds by killing seeds as they germinate rather than controlling established plants. They are used around ornamental trees, shrubs, flowers, roses, groundcovers and in some vegetable garden applications—always follow the product label for approved uses and timing.

Planting windows vary by product; some labels specify intervals from 1 to 30 days after application. Always follow the product label for the recommended safe planting interval for vegetables, flowers, or turf.

Some lawn concentrates list specific active ingredients such as sulfentrazone and quinclorac.

When mixed per label directions, many product details state one gallon of spray solution typically covers about 300 square feet.
