Picloram has similar mode of actions 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. It is active over a wide range of plant species. Picloram has been reported to be a better choice of auxin over 2,4-D in inducing callus as it is active at a lower concentration.

Typical working concentration of picloram varies by plant species.
It has been reported that strawberry culture treated with 2 mg/L of picloram produced a high percentage of embryogenic calli and embryos at globular stage; while at 1 mg/L of picloram produced highest number of embryos at cotyledonary-stage. Other plant species such as tomato have been reported to induce calli when treated with 2 mg/L (8.88 µM) of BA and 0.99 mg/L (4.13 µM) of picloram. It has also been reported that sugarcane treated with 4 mg/L of picloram resulted in better callus induction and proliferation when compared with 2,4-D, IAA, and dicamba.
