A pyridine derivative represented by general formula (I), a process for producing the same, and a herbicide comprising the same. In formula (I) W represents oxygen, sulfur, NH or N-C(O)B wherein B represents hydrogen or alkoxy; and Z represents methine or nitrogen. This compound has an excellent herbicidal effect on annual and perennial weeds growing in lowland and upland fields even in an extremely low dose. Since it is harmless to wheat, cotton and corn, it can be used as a herbicide in the fields where these crops are cultivated.
由通式(I)代表的吡啶衍生物、生产该衍生物的工艺以及包含该衍生物的除草剂。在式 (I) 中,W 代表氧、硫、NH 或 N-C(O)B,其中 B 代表氢或烷氧基;Z 代表甲烷或氮。这种化合物对生长在低地和高地的一年生和多年生杂草具有极佳的除草效果,即使剂量极低。由于它对小麦、棉花和玉米无害,因此可用作种植这些作物的田地的除草剂。
