Diflufenican is broad spectrum herbicide for gramineae and broad leaved weeds, such as cleavers , brooklime and violales.
Diflufenican
Chemical name: N-(2,4-difluorophenyl)-2-[3-(trifluoromethyl)phenoxy]-3-pyridinecarboxamide
Product category: herbicide
Appearance: white powder
MF: C19H11F5N2O2
CAS No. : 83164-33-4
Molecular Weight : 394.3
Melting point: 161-162°C
B.p.: V.p.: 4.25 × 10-3 mPa (25 °C, gas saturation method) Henry: 0.033 Pa m3 mol-1S.g.
Solubility: In water <0.05 mg/l (25 °C). Soluble in most organic solvents, e.g. acetone, dimethylformamide 100, acetophenone, cyclohexanone 50, isophorone 35, xylene 20, cyclohexane, 2-ethoxyethanol, kerosene <10 (all in g/kg, 20 °C).
Stability: Stable in air up to melting point. At 22 °C, very stable in aqueous solution at pH 5, 7 and 9. Fairly stable to photolysis.
Toxicity: (Rat):
Oral: Acute oral LD50 for rats >2000, mice >1000, rabbits >5000 mg/kg.
Skin and eye Acute percutaneous LD50: for rats >2000 mg/kg. Non-irritating to skin and eyes (rabbits).
Inhalation: (4 h) for rats >2.34 mg/l air.
Birds: Acute oral LD50 for quail >2150, mallard ducks >4000 mg/kg.
Fish: LC50 (96 h) for rainbow trout 56-100, carp 105 mg/l.
Bees: Non-toxic by ingestion or contact.
Daphnia: LC50 (48 h) - no effect at 10 mg/l.
Algae: No growth inhibition of algae (96 h) at 10 mg/l.
Worms: Non-toxic to earthworms.Other aquatic spp
Mode of action: Selective contact and residual herbicide, absorbed principally by the shoots of germinating seedlings, with limited translocation.
Uses: Applied at 125-250 g/ha pre- or early post-emergence in autumn-sown wheat and barley to control grass and broad-leaved weeds, particularly Galium, Veronica and Viola spp. Normally used in combination with isoproturon or other cereal herbicides. Phytotoxicity: Any slight phytotoxicity is in the form of small transient patches on basal leaves, with no adverse effect on crop development.
