Oxalic Acid - New Advances in Varroa Control
This meeting was recorded, and will be available to view until October 20, 2021
EVENT DESCRIPTION:
Oxalic acid is an important tool for controlling varroa mites, IF you use it correctly. What is the best method? Vaporization? Dribble? Shop Towel? How much is too much? How often is too often? Will it hurt your queen? Is it only effective when your colony is broodless? If mites under wax cappings escape a first treatment, can you safely use consecutive treatments to kill them?
Dr. Medhat Nasr will present science-based answers to these questions and more.
