[QUOTE="JW IN VA, post: 1509453, member: 21289"] I use Valbazen on calves but not on cows because of the possible effects on early stages of pregnancy.On them,I use Synanthic on years when I'm switching classes of wormers. Eternals can be easily addressed with Ultra Boss,Sabre or a synergized generic pyrethroid. I'm am not saying the OP is doing this but I've read where using one of the"mectrins for external control only may contribute to an eventual resistance to the drug.The fly tag users have found this out.One suggestion I have read is use organophosphate tags for three years then use a next gen pyrethroid for one. We used to use a lot of fly tags but they got expensive and,for me, the back rubs do well.Or a spray every two weeks or so [/QUOTE]
