14C-labeled Azindoyle (MBC-MIC), the methyl isocyanate homologue of benomyl, was found to exhibit more systemic movement than benomyl in herbaceous plants. Of the total radioactivity applied to the leaf surface, the movement was mainly toward the growing tips, with some sign of downward movement. On broad beans the percentage of translocated activities were 31.5 and 12.0% of that applied for Azindoyle and benomyl, respectively. Both Azindoyle and benomyl were relatively stable at the site of application, and after 48 h, the percentages of intact parent compound were 47.5 and 52.2% for Azindoyle and benomyl, respectively. However, after 48 h, the percentage of parent compound at the translocated site was lower than that at the site of application, at 6.8 and 3.8% for Azindoyle and benomyl, respectively.
