Potato spindle tuber viroid (PSTVd) effects tomato, pepper and other solanaceous hosts. Symptoms include stunting, severe yellowing and distortion of the leaves. PSTVd is seed transmitted. 1500 seeds are tested for Potato spindle tuber viroid (PSTVd) by real time RT-PCR (TaqMan). However, this TaqMan assay also detects Tomato chlorotic dwarf viroid (TCDVd), Mexican papita viroid (MPVd) and Tomato planta macho viroid (TPMVd).
Further viruses are available for an additional fee. These are Potato leaf roll virus (PLRV) and potato viruses PVA, PVV and PVX.
