– This ELISA test is a qualitative serological assay for the detection of Peanut stunt virus (PSV), also known as groundnut stunt, in bean and peanut leaves and seed. PVS is a member of the Cucumovirus genus known for their non-enveloped, spherical virus particles.
Peanut stunt virus causes severe disease in beans and peanuts. It can also infect a large number of other crops, including alfalfa, clover, cucurbits, tobacco, and tomato.
The aphids, Myzus persicae, Aphis craccivora, and Aphis spiraecola can all transmit PSV in a non-persistent manner. These aphid vectors can spread PSV to highly susceptible crops from reservoir host legumes such as alfalfa and clover, where it can overwinter. PSV can also be seed-transmitted.
