RESISTANCE MANAGEMENT RECOMMENDATIONS: InCide 25 Fly Killer contains the synthetic pyrethroid permethrin (a Group 3 Insecticide). Any insect population may contain individuals naturally resistant to permethrin and to other Group 3 Insecticides. Continuous or repeated exposure to insecticides of this group rapidly selects for resistant pests, eventually leading to the failure of the insecticide to provide satisfactory control. Permethrin resistance has already been recorded in horn fly populations in Canada. The use of this product should therefore conform to current resistance management strategies.

To delay insecticide resistance:

1. Where possible, rotate the use of InCide 25 Fly Killer Insecticide with insecticides of other groups that control the same pests.

2. Insecticide use should be based on an IPM program that includes scouting, record keeping, and considers cultural, biological and other chemical control practices.

3. Monitor treated pest populations for resistance development.

4. Consult with local provincial authorities and extension specialist for advice on any additional pesticide resistance-management and/or IPM strategies to control cattle pest populations in your area.

5. For further information or to report suspected resistance contact Engage Animal Health at (519) 826-7878.
