Weed problem on the newly established prairie cordgrass (Spartina pectinata) plantations intended for energetic purposes

In our research conducted in years 2009-2011 three herbicides were examined in the respect of their usefulness at the plantation of prairie cordgrass (Spartina pectinata) intended for energetic purposes. In the light of the conducted observations, it seems that selectivity of particular herbicides for prairie cordgrass plants and their effectiveness on particular weed species depend mainly on the growing phase of the plants as well as on particular weed species.
