Substituted propionanilide

Available evidence suggests that arylamide bonds generally are quite resistant to hydrolytic attack in plant tissues. A notable exception, however, is the substituted propionanilide propanil (2), which is rapidly hydrolyzed in resistant rice plants but not in susceptible weeds such as Echinochloa crus-galli (Figure 10.2). Hydrolysis of propanil is mediated by a specific...
