Title: Selective Mode of Action of Naproanilide in Rice and Paddy Weeds- II. Uptake and Translocation of Naproanilide in Rice and Paddy Weeds
Abstract: In order to determine selective mode of action of naproanilide between rice and paddy weeds, absorption and translocation of -naproanilide in rice, Echinochloa crus galli, Cyperus serotinus, and Sagittaria pygmaea were studied, Rice plant and Echinochloa crus-galli absorbed less amount of -naproanilide than Sagittaria pygmaeo and Cyperus serotinus. Less amount of -naproanilide was translocated into shoots and translocation rate was slower in rice and Ecl:inochloa crzis-galli than that of Sagittaria pygmaea and Cyperars serotinus. Also, 30-40% of -naproanilide was distributed at tubers of Sagittaria pygmaea and Cyperus serotinus, which explained that higher amount of -naproanilide was absorbed from tubers. -naproanilide was gradually decreased in all plant species and finally more radioactivity was determined in Sagittaria pygmaea and Cyperus serotinus than in Echinochloa cars-galli and rice plant after -naproanilide treated plants were transferred to Kasugai solution.
