The main use of picloram salts and esters is for the management of unwanted vegetation in rangeland, grass pastures, forestry, as well as non-crop land and rights-of-way sites such as around industrial and military installations, roads, railways, airports, under powerlines and along pipelines. In some countries, there are additional uses in rice, sugar cane, cereals and oilseed rape.
