needle-cast on my Sciadopitys verticilla
I have what appears to be needle-cast on my Sciadopitys verticilla. Which fungicide do I spray it with? We have had almost monsoon conditions this spring and summer so far. The whorls on tip of branches keep getting the brown needles and then drop them. I have tried Clears 3336, and today I tried Banrot that I had. I've removed all infected whorls, raked dropped needles and discarded, and sprayed soil after removing needles. Can you give any advice? This is a 6' tree and I would hate to lose it! Thank you so much!

In my research I found a few links for you that may be of some help.
One of the links strongly suggests that a professional needs to make the diagnosis of Needle Cast disease.
