Selectively herbicidal 4-amino-6-tert-butyl-3-ethylthio-1,2,4-triazin-5(4H)-one

Selectively herbicidal 4-amino-6-tert-butyl-3-ethylthio-1,2,4-triazin-5(4H)-one. Eue, Ludwig; Schmidt, Robert; Dickore, Karlfried (Bayer A.-G. , Fed. Rep. Ger.). Can. CA 1167269 A1 15 May 1984, 30 pp. (English). (Canada). CODEN: CAXXA4. CLASS: IC: A01N043-64. APPLICATION: CA 81-385904 15 Sep 1981. PRIORITY: DE 80-3041587 4 Nov 1980. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 28 4-Amino-6-tert-butyl-3-ethylthio-1,2,4-triazin-5(4H)-one (I) [64529-56-2] at 0.01-5 kg/ha is suitable for selectively combating monocotyledon and dicotyledon weeds in wheat, barley, corn, and pea crops before and after emergence of the plants without causing any phytotoxic effects. Thus, I was prepd. by adding EtBr [74-96-4] (572 g) to a soln. of 1000 g 4-amino-6-tert-butyl-3-mercapto-1,2,4-triazin-5(4H)-one [33509-43-2] in 1N NaOH soln. at 50°. 4-Amino-6-tert-butyl-2-ethyl-1,2,4-triazin-5(4H)-one-3(2H)-thione [91990-73-7] was obtained with I as a byproduct (19%). A wettable powder formulation was prepd. contg. I 60, arylalkylsulfonate 3, spent sulfite liquor 3, HCHO-cyclohexanone-NaHSO3 condensate 5, and silicic acid + Al2O3 10 parts. I was superior to its homolog (4-amino-6-tert-butyl-3-methylthio-1,2,4-triazin-5(4H)-one) in weed control. Combinations of I with other known herbicides, e.g. triallate [2303-17-5], diallate [2303-16-4], difenzoquat [49866-87-7], benzoylprop-ethyl [22212-55-1], flamprop-isopropyl [52756-22-6], flamprop-methyl [52756-25-9], dichlofop-methyl [51338-27-3], or chlorfenprop-methyl [14437-17-3] also are claimed.

Selective herbicides based on triazinone

Selective herbicides based on triazinone. (Bayer A.-G. , Fed. Rep. Ger.). Belg. BE 899335 A1 31 Jul 1984, 35 pp. (French). (Belgium). CODEN: BEXXAL. ICI: A01. APPLICATION: BE 21-699 5 Apr 1984. PRIORITY: DE 84-3403332 1 Feb 1984. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 28 4-Amino-6-tert-butyl-3-ethylthio-1,2,4-triazine-5(4H)-one (I) [64529-56-2] is a pre- and postemergence herbicide against mono- and dicot weeds in cereals and legumes. Thus, preemergence 1.25 kg I/ha controlled Avena fatua without injury to wheat. Synthesis was given.
