No, but in the past, there wasn't enough specificity in the testing to differentiate what type of nematode it was. The classification of nematodes is complex. There are many different species. Some of them are harmful and some are benign, and earlier on, before 2015, before the technology and the use of genetics allowed us to differentiate them, we didn't have the knowledge to be able to definitively say what was not the stem and bulb nematode. In 2015, that technology allowed us to make that case.
