Applications

Selective systemic herbicide, absorbed rapidly by the roots and leaves, and translocated both acropetally and basipetally, accumulating in new growth. 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.

Stability

Very stable to acids and alkalis, but decomposed by hot concentrated alkalis. Readily forms water-soluble alkali-metal and amine salts. In aqueous solution, decomposed by u.v. irradiation, DT50 2.6 d (25^οC).
