Asked July 30, 2014, 12:25 PM EDT

I am finding a growth of some type of "nodule" about the size of 3/4" long by 1/2" Dia.. I have seen this last year in a small numbers. This season I am seeing that number double. I have found no information on the internet about the deformity on blueberry stock.

It could be blueberry stem gall which is caused by a small wasp. I posted some pictures my most recent fruit report. The blueberry section of the report is near the bottom of the report.
