Product Information

Longer-lasting Alion® herbicide provides a superior solution for pre-emergence control of a broad range of grass and broadleaf weeds, including ALS- and glyphosate-resistant species. Alion is available for use in established citrus groves. Alion contains a unique class of chemistry (cellulose-biosynthesis inhibitor) as its active ingredient (Group 29). Alion offers excellent crop and environmental safety when used as directed. At 5 to 6.5 oz./A, Alion will provide up to 6 months of residual control, reducing the number of in-season sprays.
