| Mol. wt. **7.3 M.f. C9H*7N5S Form White powder. M.p. *6.3–*7.0 °C B.p. **7 °C/*8.6 kPa V.p. 0.**5 mPa (*5 °C) (OECD **4) Kow logP = 2.*3 (*5 °C) Henry 4.1 × ***4 Pa m3 mol*1 (calc.) S.g./density 1.*8 (*2 °C) Solubility In water **0 mg/l (pH 7.1, *2 °C). In acetone **0, methanol **0, toluene **0, n-octanol **0, hexane *2 (all in g/l, *5 °C). Stability Stable in neutral, weakly acidic, and weakly alkaline media. Hydrolysed by strong acids (pH 1) and alkalis (pH *3) to the herbicidally-inactive *-hydroxy derivative. Slowly decomposed by uv light. pKa 4.1, weak base |
| APPLICATIONS |
| Biochemistry Photosynthetic electron transport inhibitor at the photosystem II receptor site. Mode of action Selective systemic herbicide, absorbed by the leaves and roots, with translocation acropetally in the xylem, and accumulation in the apical meristems. |
| Uses Pre- and post-emergence control of most annual grasses and broad-leaved weeds in pineapples, sugar cane, bananas, citrus fruit, maize, cassava, coffee, tea, sisal, cocoa, oil palms, and on non-crop land.
