纯品为固体,原药为浅褐色固体;蒸汽压 2.4×10-2Pa(25℃);熔点68~70.6℃/纯品;57~64 ℃/原药;溶解性:水0.1mg/L ,丙酮1.25kg/L,并可溶于氯仿、二氯甲烷、乙醚、甲苯;密度:相对密度(d25)1.210;稳定性:对光稳定,在酸性介质中也较稳定,在常温下贮存一年仍较稳定,但在碱性介质中会分解;危险标记; 主要用途:为拟除虫菊酯类杀虫剂
2.对环境的影响:
联苯菊酯对人畜毒性中等,对鱼毒性很高。对大鼠急性经口毒性LD50为54.5mg/kg;对兔急性经皮毒性LD50大于2000mg/kg。对皮肤和眼睛无刺激作用,无致畸、致癌、致突变作用。对鸟类低毒,对鹌鹑急性经口毒性LD50为1800mg/kg,对野鸭大于4450mg/kg。联苯菊酯对鱼毒性很高,对虹鳟LC50(96小时)为0.00015mg/L,水蚤LC50(48小时)0.00016mg/L。但由于该药剂在土壤中具有很高的亲合作用,且其水溶性又低,故实际影响较小。本剂对蜜蜂毒性中等,对家蚕高毒。杀虫活性很高,主要为触杀和胃毒作用,无内吸和熏蒸活性。其作用迅速,持效期长,杀虫谱广。
