| Abstract: | Carbendazim was quantified employing reversed-phase high-performance liquid chromatography in rice coleoptiles, radicles and shoot portions of seedlings of different ages grown from seeds treated with the fungicide, and in shoot portions of adult plants at different times after foliar treatment with the fungicide. The highest levels of carbendazim were detected in the coleoptiles four days after germination of seeds and the radicals contained the lowest concentrations. Carbendazim residues declined with time in the shoot portions of seedlings and of adult plants. However, the levels of carbendazim detected in the shoot tissues of 21-day-old seedlings grown from treated seeds recommended dose of 10 mg a.i. 10g?1 seeds] and in adult plants 35 days after treatment (recommended dose of 0.25 g a.i. litre?1 spray fluid) correspond to the reported lasting ability of the fungicide in terms of protection against blast of rice. |
