Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts. Check the label of any pesticide referenced to ensure your use is included.

Prowl H2O recently received a federal label for use on carrots. The label currently is a supplemental label, which should be available from BASF or dealer representatives.

Prowl H2O should be applied to carrots grown on mineral soil at 2.0 pints per acre in a minimum of 10 gallons of water. Prowl H2O should be applied within two days of planting carrots. It needs to be applied to damp soil or watered in after application to be effective.

Prowl H2O controls annual grasses and several broadleaves. It is weak on composite weeds such as ragweed, groundsel and marestail. It does not control yellow nutsedge.

The label indicates that it should not be used on peat or muck soils. At the rate of 2.0 pints per acre, Prowl H2O would give minimal weed control on organic soils.
