Some months ago we discussed the use of Vigortone Mineral with IGR for control of horn flies.

We have been using this for two or three months now.  At first the cattle didn't eat much of it because the grass was green and they didn't seem to need it.  It has been dry now for about six weeks and the grass has dried up.

We went for a ranch tour today and we were surprised at the absence of flies on the cattle.  Most of them had not a single fly.  They are in good shape as well due to a good spring.

Your mineral works as advertised.   Thanks for the advice.
