Abstract
This invention provides 1,3-oxazin-4-one derivatives represented by general formula (I):
in which R1 represents a phenyl group which may be substituted; R2 represents a hydrogen atom or a lower alkyl group; R3 represents a hydrogen atom, a lower alkyl group, an aralkyl group or a phenyl group which may be substituted; R4 and R5 each independently represent a lower alkyl group; and W represents an oxygen atom or a group represented by the formula -N(R6)- in which R6 represents a hydrogen atom, a lower alkyl group, a lower alkenyl group or a lower alkynyl group. There are also provided herbicidal compositions containing the derivatives represented by general formula (II):
