The present invention provides a novel pyridine derivative having the following general formula and its salt: ##STR1## wherein R is a hydrogen atom, a hydroxyl group, an alkoxy group, an alkoxyalkoxy group, and derivatives; R.sup.1 and R.sup.2 may be the same or different, and are a hydrogen atom, an alkoxy group, a halogen atom, an alkylamino group, a dialkylamino group; Z is a methine group or a nitrogen atom; X.sup.1 is an acylamino group, a cycloalkyl group, a halogen-substituted alkoxy group, an alkenyloxy group, an alkynyloxy group, an alkoxycarbonyl group, an alkylamino group, a dialkylamino group, a phenyl group. The pyridine derivative and its salt of the present invention achieve an excellent herbicidal effect on annual and perennial weeds growing in paddy fields and upland fields at a very small dosage. The pyridine derivative and its salt of the present invention have safety to rice, wheat, cotton and corn, and can be suitably applied as a herbicide to a field where these plants are cultivated.
本发明提供了一种新型吡啶衍生物及其盐,其具有以下通用式:##STR1## 其中R为氢原子,羟基,烷氧基,烷氧基烷氧基,以及其衍生物;R.sup.1和R.sup.2可以相同也可以不同,是氢原子,烷氧基,卤素原子,烷基氨基,双烷基氨基;Z为亚甲基基团或氮原子;X.sup.1为酰胺基,环烷基,卤素取代的烷氧基,烯丙氧基,炔丙氧基,烷氧羰基,烷基氨基,双烷基氨基,苯基。本发明的吡啶衍生物及其盐,在极小剂量下对稻田和旱田中生长的一年生和多年生杂草具有优异的除草效果。本发明的吡啶衍生物及其盐对水稻、小麦、棉花和玉米具有安全性,并可适当地应用于这些植物栽培的田地作为除草剂。
