1,3-Oxazin-4-one derivatives represented by general formula (I) ##STR1## wherein R.sup.1 is a lower alkyl group, a lower alkenyl group, an aryl group which may be substituted, or an aralkyl group which may be substituted; R.sup.2 is a hydrogen atom or a lower alkyl group; R.sup.3 is a lower alkyl group, an aryl group which may be substituted, or an aralkyl group which may be substituted; and R.sup.4 and R.sup.5, independently, each is a lower alkyl group, or R.sup.4 and R.sup.5, taken together with the carbon atom to which they are bonded, combine to form a 3- to 8-membered carbocyclic group which may have a branch of a lower alkyl group. These compounds have broad herbicidal spectra and potent herbicidal activities and in addition high safety to useful crops, so that they are useful as herbicides.
以一般式(I)表示的1,3-Oxazin-4-one衍生物,其中R^1是较低的烷基团、较低的烯基团、可能被取代的芳基团或可能被取代的芳基烷基团;R^2是氢原子或较低的烷基团;R^3是较低的烷基团、可能被取代的芳基团或可能被取代的芳基烷基团;而R^4和R^5分别是较低的烷基团,或者R^4和R^5与它们结合的碳原子一起形成一个3到8成员的碳环族,该环可能有一个较低的烷基团的支链。这些化合物具有广泛的除草谱和强大的除草活性,而且对有用作物具有高安全性,因此它们可用作除草剂。
