HOARY CRESS
Hoary cress is a deep-rooted perennial that reproduces by creeping roots as well as seed. These plants emerge in early spring, blooms, and set seed by mid-summer. A single plant can spread up to 12 feet in diameter in one year. Once this plant is established, it is difficult to control. Hoary cress can be found growing along roadways, ditch banks, pasture, rangeland, and cultivated fields.
Control
Cultural: Adequately managed perennial crops and vegetation can give a competitive edge. On non-irrigated ground, established crested wheat or early grasses can provide some competition. It is extremely difficult to revegetate an area covered by this weed.
Biological: There are no known insects available to target this particular noxious weed, and it is not desirable to livestock.
Mechanical: Cultivating fallow ground can eliminate Hoary cress if it occurs within 10 days of weed emergence and continues thereafter, every two weeks. Hand pulling small areas can be effective if you include the entire root.
Herbicide: Hoary cress can be effectively controlled in rangeland, pastures, and other non-crop areas by applying products containing metsulfuron or chlorsulfuron at the bud to bloom stage.
When choosing any kind of control method, assure that your choice is suited for your particular situation. Always read and follow the entire product label before applying any herbicide. |
