I was wondering if one can make a pour on using Permethrin 10%, versus a spray on? What would percentage of 10% be. Use oil or water? How much per full size steer? I have often used 2 oz per gallon of the 10% Permethrin in mineral oil as a spray. Cattle don't really like it, and it blows all over the place. I would like to run them through a chute and just pour on.
