Christa as someone who has battled fusarium for over 40 years in my garden I would have to say that picture certainly looks like you have fusarium. The good news for you is that you have good cold winters that can kill it back so you may not see it often. Down here it is relentless and even when using highly resistant root stocks for grafting or planting highly resistant varieties it still can eventually get into many of them before the season is over. The yellowing leaves is a common symptom but it is not always a symptom. Sometimes the plant will just slowly start wilting.
