Introducing the Altosid® IGR XRB Bolus For Horn Fly Control
To enhance flexibility and convenience in cattle producers’ fly control strategies, Cargill has collaborated with Central Life Sciences to introduce a feed-through fly control bolus featuring Altosid® IGR.
An effective control program keeps horn fly levels to fewer than 200 flies per animal. This at-a-glance guide
will help you easily evaluate the effect that horn flies currently have on your herd. It’s easiest to make
the most accurate estimate in the morning, when horn flies are on the upper sides of the cows.
To achieve effective, cost effective horn fly control with Altosid® IGR, just follow these simple instructions:
To maximize beef cattle in a cow calf operation, begin feeding Altosid® IGR to your cattle before horn flies
appear in the early spring. Continue to feed Altosid® IGR during the summer months and then into fall. One
general rule is to feed 30 days before average daily daytime temperatures reach 65 degrees and 30 days after the
first frost in the fall. We call it the 30/30 Program, a proven strategy for achieving economical horn fly
control.
If mixing Altosid® IGR with free-choice feeds, such as mineral supplements, put out a five- to seven-day supply
and protect it from the rain.
To ensure cattle are consuming enough of the feed-through fly control, use one feeder for every 15 to 20
animals.
Keep the horn fly control supplement accessible to cattle by placing the feeders in areas where cattle
congregate, such as near watering holes or loafing areas.
Check feed consumption for a few days. Increase or decrease the number of feeders, or move them if necessary, to
allow for proper consumption. When used as directed, Altosid® IGR alone usually provides excellent season-long
horn fly control. If fly populations exceed acceptable levels due to migration from untreated neighboring herds,
use an approved adulticide, such as Prolate/Lintox-HD™ Insecticidal Spray & Backrubber for Livestock to
decrease the fly population.
