this virus. The virus can be introduced into a susceptible field crop by aphids from a nearby reservoir (infected perennial hosts like clover, alfalfa or perennial peanuts) and then is spread further into the field by aphids. It can be spread in perennial crops by harvesting (mechanical transmission) and possibly by root grafts. Diagnosis Correct diagnosis of any plant disease requires some expertise. Plants suspected of a viral infection should be sent to a plant diagnostic laboratory where the presence or absence of the virus can be confirmed by serological ( ELISA ), genetic (PCR), or host range tests. Antiserum and sequence data are available for this virus. Other references for Peanut stunt virus in perennial peanuts Blount, A.R., R.K. Sprenkel, R.N. Pittman, B.A. Smith, R.N. Morgan. W.
