Picloram is a pyridinemonocarboxylic acid that is pyridine-2-carboxylic acid
It is a systemic herbicide used to control deeply rooted herbaceous weeds and woody plants in rights-of-way, forestry, range lands, pastures,
and small grain crops. It has a role as a herbicide and a synthetic auxin.
It is an aminopyridine, a pyridinemonocarboxylic acid, a chloropyridine and an organochlorine pesticide.
It derives from a picolinic acid.
Picloram is a systemic herbicide used for general woody plant control.
It also controls a wide range of broad-leaved weeds, but most grasses are resistant.
A chlorinated derivative of picolinic acid, picloram is in the pyridine family of herbicides.
|Oral Acute oral LD50 for male rats >5000, mice 2000-4000, rabbits c. 2000, guinea pigs c. 3000, sheep >1000, cattle >750 mg/kg. Skin and eye Acute percutaneous LD50 for rabbits >2000 mg/kg. Moderate eye irritant; mild skin irritant (rabbits). No skin sensitisation. Inhalation LC50 for male and female rats >0.035 mg/l. NOEL (2 y) for rats 20 mg/kg daily. ADI 0.2 mg/kg. Toxicity class WHO (a.i.) U; EPA (formulation) I (based on inhalation toxicity values; however, because of low volatility, picloram can only be tested at low doses, when no deaths occurred, and any effects at higher doses cannot be determined)|
|of action Selective systemic herbicide, absorbed rapidly by the roots and leaves, and translocated both acropetally and basipetally, accumulating in new growth. Uses 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. Phytotoxicity Phytotoxic to most broad-leaved crops (except crucifers). Non-phytotoxic to established grasses, but seedling grasses may be susceptible. Formulation types SL. When picloram is formulated as a stand-alone product, it is typically as the potassium salt. When in combination with other active ingredients, picloram is formulated either as an ester or an amine salt.|
