– Agdia’s Potyvirus Group test detects most aphid-transmitted members of the Potyvirus Group. This test is based on a monoclonal antibody (PTY 1) developed by the USDA Florist and Nursery Crops Laboratory in Beltsville, Maryland, USA. The broad reactivity of this antibody is possible because it reacts to a sequence of amino acids on the virus coat protein which is highly conserved among aphid-transmitted potyviruses. This test is intended to be used as a general screening tool. We recommend confirmation of positive results by another method (PCR, etc.)

Potyviruses are the largest group of plant pathogens and affect hundreds of crops. Viruses within this genus are transmitted through one or more of the following means: aphid, seed, mechanical, graft and pollen. Potyviruses can have a significant impact on crop production including loss of yield, unmarketable product and regulatory impacts.
