CASRN 51235-04-2 molecular formula C12H20N4O2 FW 252.30 Soil/Plant. Degrades in soil and natural waters releasing carbon dioxide. The reported half-life in soil is 1 to 6 months (Hartley and Kidd, 1987). Rhodes (1980) found that the persistence of hexazinone varied from 4 wk in a Delaware sandy loam to 24 wk in a Mississippi silt loam. [Pg.1586]

Hexazinone is subject to microbial degradation (Rhodes, 1980 Feng, 1987). Metabolites identified in soils, alfalfa, and/or sugarcane include 3-(4-hydroxycyclohexyl)-6-(dimethylamino)-1 -methyl-s-triazine-2,4 (1 //, 3/7) dione, 3-cyclohexyl-6- (methylamino) -1 -methyl-5-triazine-2,4-... [Pg.1587]

Feng (1987) monitored the persistence and degradation of hexazinone in a silt loam soil 104 d after treatment of the herbicide. After 104 d, 66% of the hexazinone degraded via hydroxylation to form the major metabolite 3-(4-hydroxycyclohexyl)-6-(dimethylamino)-l-methyl-s-triazine-2,4(l//,3//)dione (30-50% yield). A minor metabolite, 3-cyclohexyl-6-(methylamino)-1-methyl-s-triazine-2,4(1//,3//)-dione, forming via demethylation, accounted for only 0-12% of the applied herbicide. Hexazinone and its metabolites were not detected in soils at depths of 15-30 cm. [Pg.1587]

No traces of hexazinone or its metabolites were detected on treated blueberries (Jenson and Kimball, 1985). [Pg.1587]

Changing the nature of the triazine substitution pattern to the l,3,5-triazine-2,4-dione system leads to another series of herbicides, of which the best example is hexazinone (1) (75USP3902887). It is built up from cyanamide which is converted in several steps to the guanidine (2). Reaction with cyclohexyl isocyanate then gives an intermediate which can be cyclized to hexazinone (Scheme 2).
