Featured Question

Last year crop was a total failure due to this. This year I have gently removed close to 6 small fruit starts. I just found some leaves on the pear with these spores. I have been treating the soil and the tree with neem granules, for soil, and neem oil spray for leaves and branches and fruit. Spraying about every 2 weeks. Still not under control. Please advise on any other methods besides cedar tree removal. I haven't found any cedars close by with this rust yet. But I believe a western red cedar in the adjacent yard was orangish in color about 2 years ago. Looks bright green now.
