Earlier this year Dr. Scot Nelson of the University of Hawaii received some photos of spotting on coffee leaves and lesions on the branches. This disease was thought to be coffee ringspot virus. However, more in depth testing identifies these symptoms to be that of Emaravirus.
Dr. Nelson is asking for help from the Hawaii coffee growers to understand the spread of this virus.
Please see Dr. Nelson's web-page for picture and more details.
If you have seen these symptoms on your plants or think you might have this virus on your coffee, please contact Dr. Scot Nelson at firstname.lastname@example.org or 808-956-2000.
