Blueberry Fungus?

guatejoJuly 10, 2012

For years I've tried to grow blueberries but they continually die back on the growing tips. In june the top 6 to 8 inches start to wilt then die back. The soft part shrivels and there are brown spots on the stem below. Does anyone know what this is or if there is a cure?

Looks like some kind of bacterial infection or maybe stem borer assuming that all other factors are up to par. What kind of water are you using? Rain water, municiple, well???

The blueberry is planted next to a small pond so does not need watering. Others are planted 50 feet from the pond and still has this problem.

I have the same problem, it's a type of canker. What I plan to do is cut the stems down to soil level and spray lime sulfur this fall and early spring. This is suppose to take care of the canker. worth a try i suppose. luke

Guate, that looks like phomopsis twig blight to me:

It wiped out my entire planting, despite my thorough soil preperation. Perhaps if I had caught it earlier, some fungicide might have saved my plants. I now have brambles in the beds--they're looking good.
