摘要
通过田间试验和气相色谱检测,研究了拜田净在水稻、土壤和水中的残留降解状况。结果表明拜田净在水稻、水中的半衰期分别为3.9～4.4天,4.8～4.9天。方法回收率水稻为86.9%～103.0%(RSD:2.3%～8.8%),土壤为89.9%～92.0%(RSD:4.7%～5.6%),水为89.6%～100.0%(RSD:8.1%～10.8%)。
Residue and degradation of fentrazamide in rice, soil and water was studied by GC. The half life were3.9- 4. 4days（rice）and4.8- 4.gdays（water）. The recovery were 86.9%- 103.0% （RSD：2.3%-8.8%） for rice and 89.9%-92.0% （RSD：4.7%-5.6%） for soil and 89.6%- 100.0% （RSD：8.1%- 10.8%） for water.
