Abstract

Abstract A series of 1, 3, 4 (2H)-isoquinolinetriones have been found to be fast-acting post- emergence herbicides, producing symptoms of desiccation. These redox-active compounds are very potent stimulators of the light-dependent consumption of oxygen at photosystem I in isolated chloroplasts. Pulse radiolysis studies on 2-ethyl-1, 3, 4 (2H)-isoquinolinetrione have shown it to have free-radical properties which could enhance the generation of ...
