| 摘 要： | 采用盆栽法研究了灭线磷在土壤、番茄植株和果实中的残留动态。结果表明剂型不同，灭线磷的降解速度不一样，乳油型灭线磷的降解速度高于颗粒剂型灭线磷。10％灭线磷颗粒剂在用量分别为60，120kg／hm^2时其在土壤中的半衰期分别为22．4，23．6d，在植株中的半衰期分别为4．7，3．9d；40％灭线磷乳油用量为15L/hm^2时，其在土壤、植株中的半衰期分别为13．8，3．9d。番茄收获（间隔97d）时，果实和植株中均无灭线磷残留检出。

| Abstract: | The resu lts of a pot experim ent showed that the degradation rate of ethoprophos emu lsifiab le concentrate(EC) was greater than that of ethoprophos granu le(G).The half-life of 10% ethoprophos granu le was 22.4 and 23.6 days in the soil and 4.7 and 3.9 days in tom ato p lants when itwas app lied at the rate of 60 and 120 kg /hm2,respectively.W hen app lied at 15 L /hm2,40% ethoprophos EC had a half-life of 13.8 days in the soil and 3.9 days in the p lant.No ethoprophos was detected in the fru it and p lants of tom ato at harvest,wh ich was m ade 97 days after ethoprophos app lication. |
