Prowl H20 herbicide from BASF has received a Section 18 label for use in Texas Bermudagrass pastures and hay meadows, effective March 12, 2009. This label is good until June 30, 2009. The herbicide label requires application on dormant Bermudagrass, and activation by rainfall or irrigation prior to sandbur (grassbur) germination. And that time is upon us.

For a copy of the label or for more information contact the County Extension office or your local herbicide dealer. A few quick notes:

Application after sandbur emergence will not provide control of those plants, but will provide control of plants yet to germinate. Producers should scout areas of the field normally infested with grassbur to make a judgment on whether this treatment will be effective.

The herbicide label must be in the hands of the user at the time of the application.

As per the label, absolutely do not apply this product with any applicator equipment other than a multi-nozzle broadcast boom sprayer.

Good management of bermudagrass pastures and hay meadows will increase competition from bermudagrass and decrease sandburs. Proper grazing and or haying, fertilizer, weed control and aeration of your bermudagrass encourage grass to grow healthy, dense stands. These dense stands of Bermuda keep sandburs from germinating. For more information on sandbur control contact the County Extension office at 254/897-2809.
