N-aryloxyacyl-n-phenyltetrahydrophthalamic acid derivatives, methods of producing same, and herbicides containing same as effective components

Abstract From the Canadian patent

An N-aryloxyacyl-N-phenyltetrahydrophthalamic acid derivative represented by general formula (I) a process, for producing the same, and a herbicide containing the same as the active ingredient which is very useful as a, herbicide because it can be widely applied to upland field lowland, orchard, pasture, turf, forest and non-crop land and is highly safe for crop. In formula (I) X and Y represent each independently hydrogen or halogen; R1 represents hydrogen, halogen, lower alkyl, lower alkoxy lower alkenyloxy, lower alkynyloxy, lower alkoxyalkoxy or lower alkoxycarbonylalkoxy; R2 represents hydrogen or lower alkyl; R3 represents hydroxy lower alkoxy, lower alkenyloxy, lower alkynyloxy lower …
