I posted some pictures of the foliage on my Golden Russet tree the other day in which I thought the tree was being effected by scab. The consensus thoughts on the pictures is that it was not scab that my tree was suffering from. It’s been 4 or 5 days since I posted those pictures and today I notice the tree has dropped 70% of it’s leaves. The remaining leaves all have this blotchy brown look to them. It is definitely defoliating. Any chance my tree could have this disease?
