Concurrent Control of Two Aphid-Borne Potyviruses in Cucurbits by Two-in-One Vaccine.

The application of attenuated viruses has been widely practiced for protecting crops from infection by related severe strains of the same species. Papaya ringspot virus W-type (PRSV W) and zucchini yellow mosaic virus (ZYMV) devastate cucurbits worldwide. However, the prevailing of these two viruses in cucurbits cannot be prevented by a single protective virus.
