Re: A shift in message? The case for IPM instead of bond as the path to TF for new ba
So far, I got 3 packages in the spring (2019) and installed them with stores. I did the same OAV (oxalic) treatments on all of them. I did 1 OAV 3 weeks after install. They replaced their queens 1 month later. I did 3 rounds of 4 OAV treatments starting in late summer, then 1 round of 2 treatments (on 12/23, 12/24).
I did a heavy open feeding + sugar bricks in late fall. They started winter with 4 mediums. The top mediums were added late with empty comb and frames. I This winter, the low was around 0 degrees F. They always fly above 45 F with no rain. Last week, I did my 1 winter check. They look as big as in the fall. They ate the bricks. I'm adding 4 lb bricks around 2/28. I ordered 2 TF queens from Troy Hall (nhbeekeeper.com). I will multiply the Hall queens. Excluders should help to keep the package drones from mating. I should have all good queens by Fall 2020. Then, I'm going to treat 1/3 of my hives.
