Reed canary grass <br /> This species is extremely difficult to eradicate and requires repeated treatment over <br /> a period of one to three years.A combination of burning, chemical treatment and <br /> mowing can be used in accessible areas,or chemical treatment alone in inaccessible <br /> areas.The combination method starts by burning in late spring to remove dead <br /> vegetation and to stimulate new growth. When new sprouts have reached a height <br /> of 4 to 6 inches,the site can be sprayed with a 5% solution of a glyphosate herbicide <br /> appropriate for wetland habitat (e.g. Rodeo).The site is then mowed in late summer, <br /> followed by chemical application after re-growth.This treatment will stimulate new <br /> growth and germination to deplete the seed bank.The sequence of chemical <br /> treatment and mowing are repeated for at least a second season,and possibly a <br /> third until the grass is completely eradicated.Then native grass and forb seed can be <br /> broadcast or drilled. <br /> If reed canary grass is eradicated from an area, future management of the grassland, <br /> namely burning,will likely keep the reed canary in check. Monitoring and mapping <br /> new individuals or clumps should continue,however,and those individuals should <br /> be treated if burning is not adequately controlling them. If the plants are small they <br /> can be removed by digging out the entire root. Generally though, chemical treatment <br /> is more feasible. If plants are clumped,they can be treated by tying them together, <br /> cutting the blades,and treating the cut surface with herbicide. Otherwise, herbicide <br /> should only be applied in native planted areas on very calm days to avoid drift to <br /> non-target plants. <br /> Friends of the Mississippi River Bailey Point Nature Preserve NRMP <br /> 82 <br />
