R4 #52 Purple Flame SDWK P9297549

This plant tested positive for DMV/DCMV in Round 1. It was planted late (but before I got the results back) so it didn't get as big as it might have. The growth continued to look healthy, though, so I sent it in for retesting. This time, it came back negative for DMV/DCMV, but positive for TSV. What happened?
