Abstract
NEW MATERIAL:The compound of formula I (R is halogen, lower alkyl, lower alkoxy, nitro or trihaloalkyl; R1 is lower alkyl; R2 is lower alkoxy; n is integer 0W 5; provided that when n is 0, R1 is not methyl and R2 is not methoxy).
EXAMPLE: 2-Methyl-3-methoxy-6-(m-chlorophenyl)-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 is prepard by reacting the compound of formula II (R3 is lower alkylthio) with an alkali metal alkoxide of formula R2M (M is alkali metal).
