| Hi all,
I'm sad to report that it looks like at least 4 blueberry bushes that were planted just last year are showing widespread infection of Botryosphaeria Stem Canker (they have the trademark red lesions on relatively new growth . . . see the picture on page 8 (one of the slides on the bottom) http://www.grapesandfruit.umd.edu/Blueberries/ManagingAndAvoidingBlueb erryDiseasesAD0207.pdf ). And apparently there is no chemical control and the only means of control is destroying the infected plants. Ugh. I thought berries were supposed to be easy! Growing blueberries on the West Coast I never had to deal with this disease. Is this a very common disease? I don't want to destroy the infected bushes only to find out that this is so endemic and everyone just tolerates the infection or plants only resistant varieties of blueberries. Also, I should add that there were no blueberry plants in my yard before last year, though it is in a residential area (there could be tons of infected plants two houses down . . . .). And I bought all of the blueberry plants I have now from Raintree (which is a pretty reputable source). Anyways, now I'm trying to figure out what to do. I have a bunch more blueberries coming in the next week and so I want to figure out if I need to remove the infected plants (and take actions if necessary) before the new ones arrive. Thanks in advance everyone, since this is my first major issue I've run into I'd really appreciate any words of wisdom you could provide. |

| Did your plants fruit last year? I have found that plants that are allowed to fruit too early or too heavily tend to be much more prone to disease problems. Can you post pictures of your plants? |

| In the attached link you can view a picture of the bark with a mottled red and green appearance (whatever the plants have looks a little different from plant to plant . . . perhaps different stages of disease). The attached below appears to be bubbling or boiling . . . it does not look healthy. |
