Timing & weather

Apply Kerb SC in a single application during the fall or early winter months, but prior to soil freeze-up and snow cover.
Optimum herbicidal activity occurs when applications are made under cool temperature conditions (55° F or less) and are followed by rainfall or overhead irrigation.
Apply Kerb SC only during the fall or winter months. For optimum results, apply Kerb SC during November or December. Do not make applications when the ground is frozen.
