Hi Bob,
I agree with all your observations!
Anyone doing things the same as a few years ago is gambling seriously.
What I keep hearing is that what worked a few years ago no longer
works! Mite thresholds are a thing of the past.
Many shifting to sucrose, or 50-50 blend.
Lots of nursing of dinks.
High mites or poor nutrition in late summer = collapse.
Amazingly, some very strong colonies are being produced with only
minimal mite treatments. Others have treated on a weekly basis all
fall. There are management strategies that I will write about.
Most is common sense and diligence.
Randy
