I used pinkeye shield from our local CO-OP. New to all this, didn't know there were so many strains, and definitely wasn't aware there are custom tailored vaccines for this area. Now I know.
I've mowed once already. About to have to mow again. I'm thinking my problem area is having only so many water locations. And limited shaded areas. Pasture has been good so far, knock on wood. Maybe one or two seed heads per square foot in places. In places, none. Maybe 15 percent of pasture is inaccessible to a tractor, and is stemmy. But cattle see that ground maybe 4 days our of a month.
What do you all do for flies? This far, i've sprayed them from time to time. Due to how this farm is set up, a rub wouldn't work but half the month at best. Have considered putting the mop things on my homemade (plastic barrel) mineral feeders. Anyone use the mops?
Thought about it, i could come up with a mobile rub…maybe.
Right now I am pouring about every 18 days with UltraBoss. Real effective but it would be a pain if I had cows that would not stand to be poured in the field. In that case, I would spray with a Synergized Permethrin in a small pump spray.
Sounds like a chance to see some immunity to Ultraboss and similar products pretty quickly at that pace. Are you using the 200 flies per cow threshold to treat?
I don't count them. UltraBoss begins to lose its effectiveness at about 2 weeks. I treated yesterday. Horn flies were awful. Certainly, in the range of a couple hundred but that is a guess. Dang things are small and they are hard to count when they are moving.
