Abstract
NEW MATERIAL:To compound of formula I (R is halogen, lower alkyl, lower alkoxy, NO2, or trihaloalkyl; R1 is lower alkyl; n is an integer 0W5).
EXAMPLE: 2-Methyl-3-dimethylamino-6-phenyl-5-oxo-2,5-dihydro-1,2,4-triazine.
USE: Herbicide effective remarkably against the weeds of plowed field by the soil treatment before sprouting of the weeds or by the foliar treatment of the weeds at the growing stage. It has also strong effect against annual and perennial weeds in the paddy rice field.
PROCESS: The compound of formula I can be prepared by reacting the 5-oxo-2,5- dihydro-1,2,4-triazine derivative of formula II (R2 is lower alkyl) with dimethylamine. The compound of formula II is obtained by the reaction of the compound of formula III with the alkyl halide of formula R1X in the presence of a base.
