Abstract

NEW MATERIAL:A 2-amino-5-oxo-2,5-dihydro-1,2,4-triazine derivative of formulaI(R is H, halogen, lower alkyl, lower alkoxyl, nitro or trihaloalkyl; R1 is methylthio or dimethylamino).
EXAMPLE: 2-Amino-5-methylthio-6-phenyl-5-oxo-2,5-dihydro-1,2,4-triazine.
USE: A herbicide, capable of exhibiting an effect on weeds in plowed fields, e.g. Deccan grass or large crab-grass, and broad-leaved weeds in plowed fields, e.g. green amaranth or smooth pigweed, without toxicity to main crops, e.g. corn, wheat or rice plants, safely usable for vegetables, e.g. lettuces or tomatoes, and exhibiting powerful action on annual and perennial weeds in paddy fields, e.g. barnyard grass.
PROCESS: A compound of formula II is reacted with a compound of formula III (R2 is acyl, sulfonic acid, etc.) in the presence of a base to give the compound of formulaI.
