氯溴虫腈，试验代号HNPC-A3061，化学名称为1-（2-氯乙氧）甲基-4-溴-2-（4-氯苯基）-5-三氟甲基吡咯-3-腈，是我国自主研制的一种新型吡咯类杀虫剂，主要用于防治蔬菜、水稻和棉花害虫。通过两年三地田间试验，研究了氯溴虫腈在甘蓝和土壤中的残留与消解动态。结果表明：2012年氯溴虫腈在湖南、河北和江苏三个试验点甘蓝上的消解半衰期分别为5.28、5.14、6.16 d，土壤中的消解半衰期分别为13.05、7.87、11.12 d；2013年甘蓝上的消解半衰期分别为7.17、6.42、10.73 d，土壤中的消解半衰期分别为2.75、2.32、5.94 d。根据我国农药残留等级标准，氯溴虫腈属于易降解农药。以10%氯溴虫腈悬浮剂的有效成分施药剂量18 g a.i.· hm-2和27 g a.i.·hm-2各喷施3~4次，距最后一次施药14 d，氯溴虫腈在甘蓝和土壤中的最大残留量分别为0.290 mg·kg-1和0.141 mg·kg-1，建议氯溴虫腈在甘蓝上的最大允许残留限量为1.0 mg·kg-1，安全间隔期为14 d。

Brochlorfenapyr, test code:HNPC-A3061;chemical name:1-(2-chloroethoxy)methyl-4-brom-2-(4-chlorophenyl)-5-tirflu-oromethylpyrrol-3-nitrile), is a novel pyrrole insecticide discovered by Hunan Research Institute of Chemical Industry, and is used to con-trol pest insects on crops such as vegetables, rice and cotton. Field experiments were conducted to study the residues and dissipation dynam-ics of HNPC-A3061 in Chinese cabbages, and soils in Hunan, Hebei and Jiangsu for two years. The initial deposition of HNPC-A3061 on Chinese cabbages was 2.686 mg·kg-1, 1.715 mg·kg-1 and 2.603 mg·kg-1 in 2012, and 4.859 mg·kg-1, 2.665 mg·kg-1 and 1.755 mg·kg-1 in 2013 for Hunan, Hebei and Jiangsu, respectively. The half life of HNPC-A3061 on Chinese cabbages was 5.28 d, 5.14 d and 6.16 d in 2012, and 7.17 d, 6.42 d and 10.73 d in 2013 for Hunan, Hebei and Jiangsu, respectively. The initial amounts of HNPC-A3061 deposited on soils were 1.284 mg·kg-1, 0.451 mg·kg-1 and 0.298 mg·kg-1 in 2012, and 0.705 mg·kg-1, 0.691 mg·kg-1 and 0.648 mg·kg-1 in 2013 for Hunan, Hebei and Jiangsu, respectively. In soils, HNPC-A3061 had a half life of 13.05 d, 7.87 d and 11.12 d in 2012, and 2.75 d, 2.32 d and 5.94 d in 2013 for Hunan, Hebei and Jiangsu, respectively. Based on the classification of pesticide residues of China, HNPC-A3061 was a low toxic and non-persistent pesticide. When spaying 3~4 times with the recommended dosages of 18 g a.i.·hm-2 and 27 g a.i.·hm-2, the final maximum residue levels (MRL)of HNPC-A3061 in Chinese cabbages and soils were 0.290 mg·kg-1 and 0.141 mg·kg-1 at 14 d af-ter the last application, respectively. These values were lower than the standard of 1.0 mg·kg-1 with pre-harvest interval of 14 d established by US EPA for the same class insecticide chlorfenapyr in Chinese cabbages.
