BUTACHLOR92TC

PHYSICAL CHEMISTRY Type: Herbicide Form (appearance): Light yellow to purple liquid with a faint, sweet odor. M.P.: -2.8C to 1.7C B.P.: 156C/0.5 mmHg V.P.: 2.4 × 10-1 mPa (25C) F.P.: >135C (Tag closed cup) Other properties Viscosity 37 cP (25C) S.G.: 1.076 (25C) Solubility.: In water 20 mg/l (20C). Soluble in most organic solvents, including diethyl ether, acetone, benzene, ethanol, ethyl acetate, and hexane. Stability: Decomposes at≥165 C. Stable to u.v. light. Stable indefinitely ≤45C. Henry: 3.74 ×10-3 Pa m3 mol-1 (calc.) APPLICATION Formulation types: EC; GR. Biochemistry: Inhibits cell division by blocking protein synthesis. Mode of action: Selective systemic herbicide, absorbed primarily by the germinating shoots, and secondarily by the roots, with translocation throughout the plant, giving higher concentrations in vegetative parts than in reproductive parts. Uses: Used pre emergence for the control of annual grasses and certain broadqeaved weeds in rice, both seeded and transplanted. It shows selectivity in barley, cotton, peanuts, sugar beet, wheat and several brassica crops. Effective rates range from 1.0 4.5 kg a.i./ha. Activity is dependent on water availability such as rainfall following treatment, overhead irrigation or applications to standing water as in rice culture. Storage: Butachlor shall be stored in a cool, dry and well ventilated place. It should not be stored or transported along with foods. Package: 200L drum, or according to the customer’s requirements.
