Research

In Arizona, heavily infested standard 10 frame hives (single and double stacked) were treated with HopGuard® II. Mite load was reduced significantly with 1 treatment, normal colony behavior was observed, no change in bee mortality was noted, and no residuals were found in honey.

In Saskatchewan, single brood chamber bee colonies treated with HopGuard® II achieved similar results to the Arizona trials and to the trial’s 3 consecutive applications of traditional HopGuard. Normal colony behavior was observed and hive health was maintained.

In Alberta, HopGuard® II was evaluated in heavily infested double-brood chamber bee colonies. A single application of HopGuard® II provided excellent Varroa control. Normal colony behavior was observed and hive health was maintained.
