Regarding experiments -

The researcher at University of Minnesota, Larry Zilliox, asked that anyone planning to do a study contact him. He can tell you exactly what his experimental design was, and the great thing is that he can do the statistical analyses and then report your results along with his when he publishes this year's results. His e-mail is larry@mail.co.douglas.mn.us <mailto:larry@mail.co.douglas.mn.us>
or possibly lzilliox@extension.umn.edu (this one was listed in his first report, the other in the more recent report).

If everyone who wants to try this out collaborates in the planning stage, the data can be analyzed together. The results are stronger if you all follow the same method. Also, Larry can tell you which questions have already been answered satisfactorily, and which still need to be researched. The questions now seem to be which apple varieties are suitable - some are too short-stemmed - and whether bagging leads to an increase in diseases. Apparently some cultivars seemed to have more sooty mold if bagged.

As others have said, bagging may not be practical in large orchards, but for home growers and organic growers it could be a very valuable technique.

Bagging with sandwich bags sounds interesting. ...

So I'm going to try giving it a shot with sandwich bags, paper bags, and the proverbial control group with nothing. Expect a report in September or thereabouts. If more people are willing to join in and someone with knowledge about how to do a study properly wants to give advice on what to do, that would be great. It is worth finding out whether this stuff is feasible for home growers in the midwest, as opposed to places with lower pest/disease pressure. The happy bagging stories seem to come from Oregon and such, but that may not transfer.
