In this issue, the following topics are addressed

For hop growing readers, please note that MI recently reported an uptick in powdery mildew.  Here in WI, we have not yet seen powdery mildew, but we did have our first formal report of the disease in the state in 2016 – so we know it is around.  Be on the look out for white, talcum-like colonies on leaves.  Downy mildew is still being observed in most parts of the state. A recent presentation on these diseases and fungicide information can be found here.
