Absorption translocation and metabolism of chlomethoxynil x 52 in plants


, : Absorption translocation and metabolism of chlomethoxynil x 52 in plants. Agricultural and Biological Chemistry 40(4): 683-690

Rapid absorption and degradation of chlomethoxynil were observed in seedlings of rice [Oryza sativa] and barnyard millet [Panicum crus galli]. The amounts of absorption by rice and barnyard millet, at the 2-leaf and 4-leaf stages of plants, were determined in water and soil cultures. The major metabolic products of chlomethoxynil were 2,4-dichlorophenyl 3'-hydroxy-4'-nitrophenyl ether, 2,4-dichlorophenyl 3'-methoxy-4'-aminophenyl ether and their conjugates, and 2,4-dichlorophenyl 3'-methoxy-4'-acetylaminophenyl ether. Several minor unknown substances were also detected. A major metabolic pathway of chlomethoxynil in plants was postulated.
