Diseases and pests endanger the hops
There are a number of diseases and pests that add to hops. Often an infestation can only be recognized when it is almost too late. Hops care therefore requires regularly examining the plants for changes in leaves, flowers and fruits. How to recognize diseases and pests.
These diseases and pests occur
Recognize and treat hop hull
