Hexazinone

Hexazinone is an example of an atypical triazine herbicide used for control of woody plants in reforestation areas and for selective weed control in sugarcane, pineapple, and alfalfa. The degradation of hexazinone in the rat, alfalfa, and sugarcane was originally reported by Holt (1981). The mass spectral identification of hexazinone metabolites isolated from rat urine and from sugarcane extracts was reported by Reiser et al., (1983). Established sugarcane plants grown in the greenhouse were treated by soil drench with 14C-hexazinone and harvested at plant maturity 6 months later. The total radioactive residues in mature sugarcane were less than 0.1 ppm, and the intact parent was not detected. Three major plant metabolites were identified by gas chromatography/mass spectroscopy (GC/MS) as their trimethylsilyl derivatives. They were metabolites A [3-(4-hydroxycyclohexyl)-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4(1H,3H)-dione], C [3-(4-hydroxycyclohexyl)-6-(methylamino)-1-methyl-,3,5-triazine-2,4(1H,3H)-trione], and E [3-(4-hydroxycyclohexyl)-1-methyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione]. The three major rat urine metabolites were A, B [(3-cyclohexyl-6-(methylamino)-1-methyl-1,3,5-triazine-2,4(1H,3H)-dione)], and C. Minor metabolites in urine were D [3-cyclohexyl-1-methyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione] and F [3-cyclohexyl-6-amino-1-methyl-1,3,5-triazine(1H,3H)-dione]. The metabolic pathway for hexazinone in plants and animals is presented in Figure 7.11 and involves the processes of hydroxylation, demethylation, and deamination.


Active ingredientHexazinone
Chemical name3-cyclohexyl-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4-(1H,3H)-dione
ClassificationHerbicide / Agrochemical
Formulation75%WDG, 25%SL
BiochemistryPhotosynthetic electron transport inhibitor at the photosystem II receptor site.
Mode of actionNon-selective, primarily contact herbicide, absorbed by the leaves and roots, with translocation acropetally.
UsageA post-emergence contact herbicide effective against many annual and biennial weeds and, except for Sorghum halepense, most perennial weeds, at 6-12 kg/ha. Used for selective control in alfalfa, pineapples, sugar cane and in plantations of certain coniferous species; also on non-crop areas, but not on sites adjacent to deciduous trees or other desirable plants.
Mammalian Toxicology

Oral: Acute oral LD50 for rats 1690, guinea pigs 860 mg/kg.

Skin and eye: Acute percutaneous LD50 for rabbits >5278 mg/kg. Reversible irritant to eyes (rabbits); non-irritating to skin (guinea pigs).

Inhalation: LC50 (1 h) for rats >7.48 mg/l.
