Abstract

Chemical modification of the herbicide 1‐[2‐(benzothiazol‐2‐yl)isopropyl]‐4‐methyl‐3‐phenyl‐5__H__‐pyrrolin‐2‐one (MI‐2826) has revealed a new oxazinone herbicide, 3‐[2‐(7‐chlorobenzothiazol‐2‐yl)isopropyl]‐2,3‐dihydro‐6‐methyl‐5‐phenyl‐4__H__‐1,3‐oxazin‐4‐one (MI‐3069), for use in paddy fields. In comparing the phyototoxicity of the two herbicides to transplanted rice, the latter was superior to the former and kept the same predominant characteristic to control Echinochloa oryzicola Vasin for a long period of time owing to its long‐lasting residual effect.
