Update to my RHA article on virus in rose seed

I take snapshots of web sites of interest by the simple procedure of e-mailing the site to myself. On November 15, 2002 I last took a snapshot of the Agdia Rose Virus site. At that time the PNRSV information was as follows:

Pathogen: Prunus Necrotic Ringspot Virus

Symbol PNRSV

Spread by: ?

Test protocl: ELISA

The present “Spread by” for PNRSV is: “mechanical, seed”

Thus, there has been a recent change from “?” to “mechanical, seed”
