Efficacy of doramectin 0.5% w/v Pour-On for control of the horn fly, Haematobia irritans.
In 1998, three groups of cattle at three locations in Lousiana were treated with Dectomax((R)) (0.5% doramectin) Pour-On and horn fly populations were monitored. Acceptable levels (less than 50 flies per side) of horn fly control were observed from 4 to 8 weeks. Differences in the length of control among the three sites were most likely affected by immigration of adult flies from untreated groups. In 1999, acceptable horn fly control was obtained for 13 weeks by the use of two treatments of doramectin Pour-On.
