ORAL: LD50 = >5000 mg/kg (rat) (56)
B. SUBACUTE AND CHRONIC TOXICITY:
In 2-yr feeding trials rats receiving 1000 mg/kg diet suffered no
IV. ENVIRONMENTAL CONSIDERATIONS
Moderate hazard to birds, fish and beneficial insects.
Phytotoxicity has occurred when mixed with certain organophosphorous
It is rapidly metabolized in rats and is excreted in the urine as
the sulphate conjugate of 3,5-dichloro-4-aminophenol. In plants it is
metabolized to polar compounds (26).
