Feeding Instructions

Provide this block as a free choice source of nutritional
supplementation for your cattle. When used as directed, this block provides sufficient diflubenzuron to prevent fly emergence from the manure of treated cattle. This product prevents the development of horn flies, face flies, house flies, and stable flies in
the manure of treated cattle. Existing adult flies will not be affected. Start feeding this product early in the spring before flies begin to appear and continue feeding throughout the summer and
into the fall until cold weather restricts fly activity. Allow free choice to cattle. Cattle should consume an average of 0.1 mg of diflubenzuron per kg of animal body weight per day, to achieve control of horn flies, face flies, house flies, and stable flies. Cattle
should consume an average of 0.8 ounces of this product per 100 lbs of animal body weight per day, which is equivalent to 8 ounces per day for a 1,000 pound cow.

CAUTION: Use as directed. Feeding added selenium at
levels in excess of 0.3ppm in the total diet isprohibited.
