Abstract
A method of aiding in ripening and curing tobacco by application to the tobacco plant of an effective amount of a compound selected from a group comprising imidazolinones; sulfonylureas; triazolopyrimidinesulfonanilides; and pyrimidinylthiobenzoic acids and related compounds.
Claims29
A method of aiding in the ripening of a tobacco plant wherein ripening is induced by preharvest application to the tobacco plant of an effective but non-phytotoxic amount of a compound:
- 2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]arylcarbox ylate, wherein the arylcarboxylate is selected from a group comprising quinolin-3-COOR.sup.1, R.sup.2 -benzene-COOR.sup.1, and 5-R.sup.3 -pyridine-3-COOR.sup.1 ;
- R.sup.1 is H, CH.sub.3, ammonium, or lower alkylamine, R.sup.2 is 4-CH.sub.3 or 5-CH.sub.3, R.sup.3 is H, CH.sub.3, CH.sub.2 CH.sub.3, or CH.sub.2 OCH.sub.3.
A method of aiding in the ripening of a tobacco plant wherein ripening is induced by preharvest application to the tobacco plant of an effective but non-phytotoxic amount of a sulfonylurea:
- QNHCONHSO.sub.2 W,
- where if Q is 4-methoxy-6-methyl-triazin-2-yl, W is 2-R.sup.4 -phenyl, and R.sup.4 is 3,3,3-trifluoropropyl, 2-chloroethoxy, chloro, or methoxycarbonyl;
- where if Q is 4-R.sup.5 -6-R.sup.6 -triazin-2-yl, W is 6-R.sup.7 -2-methoxycarbonylphenyl, R.sup.5 is ethoxy or 2,2,2-trifluoroethoxy, R.sup.6 is methylamino or dimethylamino, and R.sup.7 is hydrogen or methyl.
A method of aiding in the ripening of a tobacco plant wherein ripening is induced by preharvest application to the tobacco plant of an effective but non-phytotoxic amount of a sulfonylurea:
- XNHCONHSO.sub.2 Y,
- where if X is 4-methoxy-6-methyl-pyrimidin-2-yl, Y is 3-R.sup.8 -pyridin-2-yl, and R.sup.8 is dimethylaminocarbonyl;
- or Y is 4-methoxycarbonyl-3-chloro-1-methyl-1H-pyrazole-5-, 1-methyl-4-(2-methyl-2H-tetrazol-5-yl)pyrazole-5-, or 2-cyclopropoxycarbonylphenylamino;
- where if Y is 2-R.sup.9 -phenyl, and R.sup.9 is a carbonyl group substituted with ethoxy-, methoxy-, or 3-oxetanyloxy-, X is 4-R.sup.10 -6-R.sup.11 -pyrimidin-2-yl, where R.sup.10 is chloro, methyl, methoxy, or difluoromethoxy, and R.sup.11 is methyl, methoxy, or difluoromethoxy;
- where if X is 4,6-dimethoxypyrimidin-2-yl, Y is 3-ethylsulfonylpyridin-2-yl, or 2-ethylsulfonylimidazo[1,2-a]pyridin-3-yl.
