MSU Extension Hops

Producing high quality hops requires careful attention to numerous insect, disease, and weed pests, as well as horticultural practices that may worsen or suppress these pests. The damage these organisms may cause ranges from insignificant to complete loss from reduced yield or diminished quality that can render hops unusable.
