I've had major problems with fungal diseases (Phytophthora for one) over the years that have prevented me from growing AGs for about 10 years. Last year I tried again and was able to at least set some fruit but eventually my plants and fruit succumbed to vine and stem rot. I was told by a grower with similar experiences that I might have "gummy stem blight" and "black rot". This year I have a number of leaves on my 845 Bobier plant that have lesions similar to ones that I have had in the past (Please check out my most recent photos in my grower's diary dated June 4 when they are posted. So far I have applied a soil drench of Subdue Maxx and Clearys and foliar applied Aliette. I was going to spray with Quadris toward the end of the month, but maybe I should use it sooner. I'd greatly appreciate any opinions and advice you can give me. Charlie

A bit early to tell for sure, Charlie. However, this looks like it may be gummy stem blight affecting your leaves. Most listings on treating this advocate Daconil, but in my experience it may control if you are lucky, but not eliminate. I am looking for advice on systemic treatment of GSB myself, and Quadris is listed for "resistant" GSB, to be used in combination with Daconil, but not by itself. I don't know what other treatment options there may be. -- Chris

Fallow or Basamid...pathogens generally are recommended to a three or four year fallow treatment of host plants...basimid will sterilize the soil of everything requiring a re innoculation of the good stuff! usually a 2 week process with the right temperatures.
