About Quack grass:
Quack grass is a perennial weed that reproduces by both seed and underground stems, also known as rhizomes. Quack grass stems generally can grow to be as tall as 4 feet. Quack grass has a thin stem and has flat smooth leaves. Quack grass grows all over Ontario, and can be sustained in all soil types, which makes this weed even more dangerous.
Family: Grass Family (Gramineae)
Quack grass Scouting and Prevention:
A good way to protect crops against Quack grass is to take frequent weed counts of crops. Doing these random checks will allow you to notice if anything in the field begins to change, and will allow you to notice if this wee does appear in fields or surrounding areas. Quack grass does however like to densely settle into concentrated areas.
Quack grass Control:
Tilling has been known to help reduce reproduction of Quack grass because it pulls up the rhizomes that reproduce the weed underground. Pre and post harvest herbicides are essential to controlling the reproduction and growth of Quack grass. Mowing on a regular basis has also been effective in some cases. Glysophate herbicides are effective in pre and post season, but pre-harvest herbicides are known to be the most effective.
