Clopyralid and picloram are both herbicides in their own right, and are used in combination to treat broad leaved weeds of oilseed rape, increasing the flexibility of use and efficiency.  The post-emergance weeds controlled by a combination treatment of clopyralid and picloram include mayweeds, cleavers, creeping thistle, sow-thistle and groundsel. It also reduces the risk of admixture and seed return.  Picloram and clopyralid are both systemic herbicides that are translocated to the roots of the plant. Picloram is a synthetic plant growth regulator, specifically an auxin-mimic, meaning it imitates the growth promotion action of the plant hormone auxin, causing uncontrolled, disorganised growth ultimately leading to vascular tissue disruption and plant death.  Clopyralid is also a synthetic auxin, but it is more selective in its target organisms. Visual symptoms of treatment with picloram and clopyralid include foliar discolouration and leaf and stem distortion.
