Application Notes
Dicamba has similar activities to other auxins, e.g., adventitious root formation, induction of somatic embryos, cell division, callus formation and growth, inhibition of axillary buds, inhibition of root elongation. Other activities of dicamba have been observed. It has been reported that disruption of normal growth with morphological and cytological aberrations were observed when wheat and barley were treated with dicamba during their high meristematic activity. 2

Typical working concentration of dicamba varies by application and plant species. Effective concentrations of dicamba have been reported on various monocotyledons in inducing embryogenic callus formation. 3 Treatment of monocot species such as Dactylis glomerata at 40 µM, Musa at 90.5 µM and rice at 4.5 – 18.1 µM with dicamba have been reported3 ; however; a low concentration of dicamba at 0.09 µM has been reported for use in wheat regeneration. 4

Dicamba is heat labile5 and should be added aseptically to autoclaved medium that has been cooled enough to handle.

PhytoTechnology Laboratories® also carries Dicamba Solution (1 mg/mL), Product No. D165.
