Project Leader: P. Griffiths, Horticultural Sciences, Cornell University, NYSAES, Geneva

Abstract: Aphid-transmitted viruses have caused devastating yield losses in snap bean production regions of NY in the last 5 years.  Cucumber mosaic virus (CMV) appears in almost 100% of infected fields; however, bean yellow mosaic virus and clover yellow vein virus are also prevalent.  Chemicals are ineffective, as aphids do not life-cycle on snap beans, leaving host-plant resistance as the only viable approach to managing these viruses.
