Characterisation of viruses affecting weeds - 1. Mosaic diseases.

Abstract

Amaranthus viridis and Trianthema decandra were hosts of the amaranthus mosaic virus. The virus could be transmitted by the aphids Aphis gossypii, A. craccivora and Myzus persicae. Both Solanum nigrum and T. portulacastrum harboured the chilli mosaic virus; A. gossypii, A. euonymi, A. craccivora and M. persicae were able to transmit the virus. The virus isolates were identified as strains of the potato virus Y. See also WA 23, 1091.
