This is from Erin Lizotte, Michigan State University Hops Specialist, and co-chair of the Great Lakes Hops Working Group along with our OSU Extension Educator Brad Bergefurd and MSU’s Rob Sirrine,
Please heed her call to action to control Downy Mildew. We have all worked too hard on our yards to let it get away from us now!
“This cool wet weather is going to continue and is making us nervous about downy mildew! Growers should be maintaining a tight 7-day spray interval and rotating through a few of the most effective products including Curzate, Forum or Revus, Zampro, and Ranman. For more information on downy mildew of hop, check out this article http://msue.anr.msu.edu/news/michigan_hop_scouting_report_april_28_2017

I know there are some organic hops growers out there, as well. What are some of the DM controls you can suggest to growers?
