| General info | Common name: terbutryn; terbutryne IUPAC name: N2-tert-butyl-N4-ethyl-6-methylthio-1,3,5-triazine-2,4-diamine Chemical Abstracts name: N-(1,1-dimethylethyl)-N'-ethyl-6-(methylthio)-1,3,5-triazine-2,4- diamine |
| Properties | PHYSICAL CHEMISTRY Composition: Tech. is 98%. Mol. wt.: 241.4; M.f.: C10H19N5S; Form: White powder. M.p.: 104-105C. B.p.: 274C/101 kPa. V.p.: 0.225 mPa (25C) (OECD 104). KOW: logP = 3.65 (25 oC, unionised). Henry: 1.5x10-3 Pa m3 mol-1 (calc.) S.g./density: 1.12 (20C). Solubility: In water 22 mg/l (22C). In acetone 220, hexane 9, n-octanol 130, methanol 220, toluene 45 (all in g/l, 20C). Also readily soluble in dioxane, diethyl ether, xylene, chloroform, carbon tetrachloride, dimethylformamide. Slightly soluble in petroleumether.Stability: Stable under normal conditions. The methylthio group is hydrolysed in the presence of strong acids or alkalis. At 70C, no significant hydrolysisCcurs at pH 5, 7, or 9. pKa: 4.3, weak base. |
| Applications | Biochemistry: Photosynthetic electron transport inhibitor at the photosystem II receptor site. Mode of action: Selective herbicide, absorbed by the roots and foliage, with translocation acropetally through the xylem, and accumulation in the apical meristems. Uses: Used pre-emergence in winter cereals, at 1-2 kg a.i./ha, to control blackgrass and annual meadow grass. Among the autumn-germinating broad-leaved weeds controlled are chickweed, mayweed, poppies and speedwell, but cleavers are rather resistant. Other pre-emergence uses are on sugar cane and sunflowers; and, in mixture with terbuthylazine, on beans, peas and potatoes. In mixture with metolachlor, used in cotton and peanuts. Also used post-emergence (0.2-0.4 kg/ha) in cereals, (1-3 kg/ha) in sugar cane, and as a directed spray in maize. As 'Clarosan', it is used to control algae and submerged vascular plants in waterways, reservoirs and fish ponds. |
