Serologiske og molekylære tests er kommercielt tilgængelige<ref name="Edis.ifas.ufl.edu"/> til diagnosticering af TSWV og en anden almindeligt forekommende tospovirus i prydplanter, ''[[Impatiens necrotic spot virus]]'' (INSV).  Cytologiske studier af TSWV og INSV har vist, at disse virus producerer granulære inklusioner i [[cytoplasma]] på inficerede planter. Disse inklusioner kan ses i lyse mikroskoper med passende farveteknikker.<ref>{{Cite web |url=http://www.freshfromflorida.com/Divisions-Offices/Plant-Industry/Science/Florida-Plant-Viruses-And-Their-Inclusions/Florida-Plant-Viruses-And-Their-Inclusions |title=Materials and Methods for the Detection of Viral Inclusions |access-date=23. maj 2016 |archive-date=13. oktober 2014 |archive-url=https://web.archive.org/web/20141013131205/http://www.freshfromflorida.com/Divisions-Offices/Plant-Industry/Science/Florida-Plant-Viruses-And-Their-Inclusions/Florida-Plant-Viruses-And-Their-Inclusions |url-status=dead }}</ref>  Disse inklusioner kan diagnosticeres.
