Abstract

Alfalfa Mosaic Virus (AlflMV) was recorded on 21 hosts comprising of four field crops, 14 vegetables, one ornamental plant and two new weed species (Heliotropium europaeum and Ammi majus) belonging to nine families. The virus was identified and confirmed on the basis of its biological, serological (ELISA) and physical properties. The leaves, stem and crown from systemically infected alfalfa plant contained high concentration of the virus. It was nonpersistently transmitted by cotton aphids (Aphis gossypii). The wide host range, including virus reservoirs, seed-borne infection and insect transmission account for high incidence and distribution of AlfMV in the country. The virus isolate had a dilution end point between 1 x 10-3 to l x 10-4, 65-67 °C thermal inactivation point and a few days in-vitro longevity and appears to be similar to the AlfMV-S strain.
