The anticoagulant difenacoum was tested at two concentrations, 0-005 and 0-01%, in bait against warfarin-resistant rat infestations in farm buildings. Twelve out of the 14 treatments in which the lower concentration of the anticoagulant was used resulted in complete control. One of the remaining two treatments was probably also completely successful, but in the other a few rats, that were not eating the poisoned baits, were still active after 30 days of baiting. All six treatments done using the stronger concentration of poison were completely effective. Since it took as long to control infestations with 0.01% as with 0.005% difenacoum in treatments carried out under similar conditions, the lower concentration is recommended for use against warfarin-resistant rats.
在农场建筑物中,针对抗华法林大鼠的侵扰,对抗凝血剂敌鼠钠进行了两种浓度(0.005%和0.01%)的诱饵测试。使用较低浓度抗凝血剂的14种处理方法中有12种实现了完全控制。其余两种处理方法中的一种可能也完全成功,但在另一种处理中,一些不吃毒饵的大鼠在投饵30天后仍然活跃。使用较高浓度毒药进行的所有六种处理都完全有效。由于在类似条件下进行的处理中,用0.01%敌鼠钠控制鼠患所需的时间与用0.005%敌鼠钠相同,因此建议使用较低浓度来对付抗华法林大鼠。
