From
Cornell, dated 1989: "
Although an early study reported seed transmission of TSWV at a high rate in Cineraria and tomato, a later study found onIy 1 percent infection. The virus is present only in the seed coat and not in the embryo. Seed transmission is thus not considered important for disease spread. "
The bleach may work, but I don't think I would save seed from a TSWV infected plant all the same, unless I intended to grow it out myself and check for virus in the next generation before sharing with others. As it stands, I'm pretty sure we have thrips here but not TSWV. I sure don't want to bring it in!
