How so? I've been using Clik for years (with no unnecessary dipping) yet I haven't seen it since I've been using it.Do you use CLik, I suspect using Clik during the year makes it worse but putting washing soda in the winter dip solves it
I use aluminium sulphate in the dip, an old sheepfarmer recommended it years ago and is probaly the reason that our dipping clears the wool rotHow so? I've been using Clik for years (with no unnecessary dipping) yet I haven't seen it since I've been using it.
Prior to that, when we used a jetter to put OP on a couple of times a year, we did see it once. Next time we ran them through the jetter we made a mix up with OP, a bit of Zinc Sulphate and a bit of Virkon S (the last two specifically to clear up the dermatitis). Worked a treat and never had to treat again.
I have no doubt Zn So4 in a dip would do the same, but individual treatment would leave other sheep ready to spread it again.
