216.67
Structure Formula:

Properties:
the pure compound is colorless crystal,solubility:710mg/l in water(20℃),soluble in other organic solvent.
Application:
Terbacil is a selective herbicide used for control of both annual grasses, broad-leaved weeds, and some perennial weeds in sugarcane, apples, alfalfa, peaches, pecans, and mints. It is sprayed on soil surfaces preferably just before, or during, the period of active weed growth. Terbacil works in plants by inhibiting photosynthesis. It is a member of the substituted uracil chemical family.
Formulation:
95% TC、80%WP
Toxicity:
Terbacil has low acute toxicity [128]. Clinical signs of poisoning in rats include weight loss, pallor, prostration, and rapid breathing. In dogs, a single dose of 5 mg/kg caused repeated vomiting [128]. Terbacil may irritate the skin, eyes, and mucous membranes of the nose and throat. It is not a skin sensitizer [129]. The oral LD50 of terbacil is 5000 to 7500 mg/kg in rats [1,22]. The dermal LD50 is greater than 5000 mg/kg (the maximum feasible dose) in rabbits [1]. These rabbits did not show clinical signs of toxicity, nor any obvious gross changes caused by disease. No skin irritation and only mild eye irritation was seen in rabbits at this dose [23]. Similarly, there was no skin irritation or sensitization in terbacil-treated guinea pigs [23]. Dogs given 5000 mg/kg of terbacil exhibited vomiting and a lack of eye pupil responsiveness [128].
Packing:
