甜菜植株在大田栽培。种植前每公顷沟施~(14)C-涕灭威3公斤。一部分植株(生长植株)于播种后99天收获。其余植株(成熟植株)于播种后196天收获。进入甜菜植株的~(14)C-涕灭威等效物(总涕灭威加涕灭威亚砜及涕灭威砜,加所有含~(14)C 的其它涕灭威代谢产物)对施入量的百分比值,在生长植株中为2.8,成熟植株中为1.8。在生长植株和成熟植株中,~(14)C-涕灭威等效物的浓度(mg/kg 鲜重)分别为:外叶片3.16和0.93;内叶片0.63和0.68;外叶柄0.51和0.26;内叶柄0.15
Beet plants are cultivated in the field. Before planting, apply ~ (14) C-aldicarb 3 kg per hectare. Some plants (growing plants) are harvested 99 days after sowing. The remaining plants (mature plants) were harvested 196 days after sowing. (14) C-aldicarb equivalent entering beet plants (aldicarb plus aldicarb sulfapride and aldicarb sulfone plus all other aldicarb metabolites containing ~ (14) C) The percentage values applied were 2.8 in growing plants and 1.8 in mature plants. The concentrations of ~ (14) C-aldicarb equivalent (mg / kg fresh weight) were 3.16 and 0.93 for the outer leaves and 0.63 and 0.68 for the inner leaves and 0.51 and 0.26 for the outer petiole in both growing and mature plants, respectively Inner petiole 0.15
