Alion herbicide now registered for grapes

March 18, 2014, Guelph, Ont – Bayer CropScience Canada recently announced the registration of Alion as a pre-emergent residual herbicide for grapes.

The Group 29 herbicide provides long-term residual control of annual grassy and broadleaf weeds and is currently registered for use with tree fruit. It prevents weeds from emerging by inhibiting the growth of the developing radicle in the seed germination zone.

“Canadian grape growers will see the benefits of a completely new mode of action that provides longer lasting control compared to competitive products,” explained David Kikkert, portfolio manager for horticulture with Bayer CropScience. “This unique mode of action combined with its tank-mix flexibility makes it an excellent resistance management tool especially for glyphosate, triazine and ALS-resistant weeds.”


Alion can be tank-mixed with glyphosate, Gramoxone herbicide, and Ignite herbicide in grapes to provide control of already emerged weeds. It can be applied to established grapes of at least five full growing seasons after transplanting and when soil disturbance is finished, including hilling and de-hilling operations.

Alion is now also registered as a tank-mix with Sencor herbicide or Gramoxone herbicide in tree fruit, in addition to the previous registered tank-mixes of glyphosate and Ignite.
