Q.My Hedgerow Bush Has A Pest/disease Problem
My hedgerow bush (don’t know the name) has been infested by a pest or a disease, which has left dead leaves and big gaps in the foliage. Are you able to tell me what the problem is and what I can do to get rid of it? Thanks !

This one may be for your closest extension service. This seems to be a very nondescript disease and will likely require a soil sample be tested to know for sure.
You can try an all purpose fungicide, but it may require special attention depending on the specific disease.
