Plant diseases are pretty easy to spot, not always so easy to correctly ID. What kind of infection do you think your plant has? Short plants with slow growth sounds more like an environmental issue (nutrients, temps, pH, drainage)
The Centennial... has a lot of little ground-cover short bines.
It is exactly these short ground cover STUNTED bines that I am focusing on.
I strongly agree that ID-ing is difficult.
I really refuse to say much is set in stone, but there seems to be something wrong here.
Not always is it going to be clear if one has a problem plant... for example if a symptom is a reduction of height or fruit production (eg hop cones) to 60% of a healthy plant, one needs to know what that 100% is, and that will change over time with age and with other details.
Also, many symptons are not
diagnostic; they simply may or not be present.
One pix of HSV infection emphasizes yellow leaf spotting,
but this does not seem to be a diagnostic feature (?) of that disease.
One thing I have been wondering about in regards to my hop's troubles, is HSV.

Since HSVd symptom expression can vary significantly according to host species, host variety and viroid strain consequently, predicting the potential damage resulting from HSVd infection can be very difficult.
My feeling is the Centennial is a victim of something.
Don't know what yet, but its' growth is akward in comparison to what I have to compare it with.
Anyway, lets see how many grams dry cones are produced this year...
mine are 2nd yr;
yours are 3rd year or more... (?)
I don't know about Snow16 and Guzzibrew, but 2nd yr at least I think.
If we report what we get/see I think we will be abe to see if it is just a problem I am having,
or if it is a problem with the source material.
