Does anyone know the particular set of circumstances that result in cracking? I have safely used one or two applications at 4 ounces per 100 gallons on Empire a couple of years, but, having heard of possible cracking, I have not used the 3rd or 4th sprays that would be needed for good vegetative control of my trees on MM106.

RE: Apple-Crop: Mystery disease?
Thank you for the photos of what appears to be viroid affected apples. For your information, we have photos on our web site of fruit tree diseases caused by virus and virus-like agents (http://nrsp5.prosser.wsu.edu/nrspviru.html ) that some of you might find useful.

A 22:41 10.12.05 -0500, vous avez écrit : I suspect that the apple tree that bears these fruit is infected with the dapple apple/scar skin viroid. Thank you very much Dave and Jean-Marc. The informations you have provided are very informative and useful. In addition, I have found some pictures of this disease on the internet and unfortunately I have to agree with your diagnosis. I say unfortunately because from what I can see, there is no other issue than destruction of the affected tree. There doesn't seem to be any cure! And there is a risk of this viroid to spread to the rest of the orchard - a risk I am not ready to take! This seems to be a pretty exotic and rare disease. I probably have introduced it when I grafted some Wealthy apple on this seedling root in 1986. The source tree was obviously infected. To Jean-Marc, I also found a fiche descriptive en francais from the INRA here: http://www-intranet.angers.inra.fr/dossiers/virus/fichvir4.html where the first picture corresponds to the damage I can see on my tree. Also, the second picture on page 2 of the CTIFL document is very similar to my problem. Thanks for the help.
