BackLine Pour-on is a ready to use pour-on insecticide for control of biting lice, horn flies, rocky mountain wood ticks and sucking lice in beef and dairy cattle. BackLine contains 5% Permethrin, a synthetic pyrethroid insecticide, but this formulation is more concentrated than traditional pour-ons. Ready to use without dilution. BackLine Pour-On has no milk withdrawal period when used on lactating dairy cattle and can be used right up to one day before slaughter for beef cattle. Apply 3ml/45kg bodyweight up to a maximum of 30L per animal. Pour along the back and down the face, taking care to avoid the eyes and mouth or apply to the face with a cloth moistened with BackLine.
