According to a story from UGA by Paul Pugliese, “This year has been a terrible year for mummy berry disease due to the unusually cool, wet spring weather.

It can cause crop yield losses of 25 to 50% if not treated. You can read more about it at https://newswire.caes.uga.edu/story.html?storyid=8399&rss.
