Apply after transplanting the crowns but before new shoots have developed 3 to 4 new leaves. Do not use higher rates of Kerb SC than 5.0 pints per acre in one season. A second application of Kerb SC at the same rate may be applied 60 days or more prior to harvest in a banded treatment directed to the untreated soil surface between the artichoke rows after the ditching operation is completed later in the season. |

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.
