QBEEN is a systemic herbicide, absorbed from the leaf surface, with translocation throughout the plant, moving in both the xylem and phloem, and accumulating in the meristematic tissue. Growth ceases soon after foliar application, the actively growing tissues such as the intercalary meristem of grasses are affected first. Older leaf tissue may turn purple, orange or red before eventually becoming necrotic.

Selective post-emergence control of annual and perennial grass weeds in potatoes, soya beans, sugar beet, peanuts, oilseed rape, sunflowers, vegetables, cotton and flax.
