S.g./density 1.*3 (*2 °C) Solubility In water *3 mg/l (pH 7, *2 °C). In ethyl acetate *4, acetone *1, dichloromethane *8, ethanol *5, toluene 4.0, n-hexane 0.*1, n-octanol 8.7 (all in g/l, *5 °C). Stability Relatively stable in neutral, weakly acidic and weakly alkaline media. Rapidly hydrolysed to the hydroxy derivative in strong acids and alkalis, and at *0 °C in neutral media; DT*0 (pH 1) 9.5, (pH 5) *6, (pH *3) 5.0 d. pKa 1.6, v. weak base |
| APPLICATIONS |
| Biochemistry Photosynthetic electron transport inhibitor at the photosystem II receptor site. Maize tolerance is attributed to rapid detoxification by glutathione transferases. Mode of action Selective systemic herbicide, absorbed principally through the roots, but also through the foliage, with translocation acropetally in the xylem and accumulation in the apical meristems and leaves. |
| Uses Pre- and post-emergence control of annual broad-leaved weeds and annual grasses in maize, sorghum, sugar cane, pineapples, chemical fallow, grassland, macadamia nuts, conifers, and industrial weed control. In Europe, use is concentrated in maize and sorghum, at ≤1.5 kg/ha. Used also in combinations with many other herbicides. Phytotoxicity Phytotoxic to many crops, including most vegetables, potatoes, soya beans, and peanuts. |
| MAMMALIANÂ TOXICOLOGY |
| IARC class. 3 Oral Acute oral LD*0 for rats ***9–***0 mg tech./kg, mice >***2–***2 mg/kg. Skin and eye Acute percutaneous LD*0 for rats >***0 mg/kg. Non-irritating to skin; minimally irritating to eyes (rabbits). Not a skin sensitiser in guinea pigs, nor in humans. Inhalation LC*0 (4 h) for rats >5.8 mg/l air. NOEL (2 y) for rats *0 ppm (3.5 mg/kg daily), for dogs **0 mg/kg diet (5.0 mg/kg daily), for mice *0 mg/kg diet (1.4 mg/kg daily). ADI/RfD (EPA) aRfD 0.1, cRfD 0.**8 mg/kg b.w. [***3]; (EPA) cRfD for hydroxytriazine metabolite 0.*1 mg/kg b.w. [***3]. Water GV 2 μg/l. Toxicity Class  WHO (a.i.) U; EPA (formulation) III EC classification Xn; R*8/*2| R*3| N; R*0, R*3 |
| ECOTOXICOLOGY |
| Birds Acute oral LD*0 varies from **0 mg/kg for bobwhite quail to >***0 mg/kg for mallard ducks and ***7 mg/kg for adult Japanese quail. Dietary LC*0 (8 d) for Japanese quail (chicks) >***0, (adults) >***0 mg/kg. Fish LC*0 (*6 h) for rainbow trout 4.5–*1.0, bluegill sunfish *6, carp *6, catfish 7.6, guppies 4.3 mg/l. Daphnia LC*0 (*8 h) for D. magna *9, for Ceriodaphna dubia 4.9 mg/l. Algae EC*0 (*2 h) for Scenedesmus subspicatus 0.**3 mg/l, (*6 h) for Selenastrum capricornutum 0.*1 mg/l. Other aquatic spp. Long-term studies in aquatic ecosystems indicate no permanent damage up to 0.**0 mg/l. Bees LD*0 (oral) >*7 μg/bee; (contact) >**0 μg/bee. Worms LC*0 (*4 d) for Eisenia foetida *8 mg/kg soil. Other beneficial spp. No effect on ground beetles at 1.5 kg/ha. |
