There are pros and cons to every treatment method, and the decision to dribble or sublimate OA is no exception. A team at the University of Sussex published an excellent paper not yet published comparing three methods of oxalic application: They tested the three methods at different doses of oxalic acid. Spraying was effective, but tough on the bees, invasive, and time consuming, so I will discuss it no further. It is your support that allows me to devote my life to this site.

All donations go towards website maintenance, bee research costs typically tens of thousands of dollars per year , re-donations to fund research by others, and a small amount to partially offset the incredible number of hours that I spend in research and writing.

I guarantee that every penny is pinched and well spent! I appreciate the notes of support that I receive from all over the world. Update 29 Dec A brief take-home on their findings: Dribbling and sublimation were fairly comparable, with some notable differences.

Indeed, colonies appeared to tolerate a 4. This suggests that sublimation has less of a lasting negative effect upon the colony than does dribbling likely of greater impact in cold-winter areas with an extended period of dormancy.

Unfortunately, they did not compare a higher-dose dribble to the high dose vaporization. Nor did they take nosema samples, in order to determine the comparative effect upon nosema by treatment method. Two other practical aspects are operator safety and the amount of time involved in application. Unfortunately, this entails dropping oxalic crystals onto the hot vaporizer at each hive a safety consideration. As far as the amount of time involved in application, it took them 3 minutes per hive for sublimation, 2.

It may be the preferred method in climates with late fall and a short winter, due to its safety to the operator, quickness, and the colonies being able to rapidly recover.

I have no experience with sublimation myself, following my initial test of the effect of inhaling a little oxalic vapor resulting in gut-wrenching coughing. However, when testing in Canada during cold weather, Dr. Medhat Nasr found that such vaporizers may overheat and degrade the oxalic acid resulting in reduction of efficacy or not adequately penetrate the winter cluster. There would just be hundreds more white columns here in the middle with the few green tiles way off at the end.

And, the lack of disease-preventing compounds may be compounded by the presence of disease-promoting compounds. And, the more plant-based we get, apparently, the better.
