Invasive to Watch This Month

The non-native, invasive grass tall fescue (Festuca arundinaria) can be treated with glyphosate on warm days during the winter. The recommended control is through a foliar application of glyphosate with surfactant added. Often multiple applications are necessary to eradicate an established stand. One quart of glyphosate per acre in the winter is recommended. For spot treatment of isolated tall fescue plants, use 1% to 2% of glyphosate with surfactant.
