    Impacts:
    Disease transmission: Kashina, Mabagala and Mpunami (2003) found that A. conyzoides is a new weed host and disease reservoir of the Tomato yellow leaf curl Tanzania virus near tomato farms in Dodoma, Tanzania. A. conyzoides and Sida acuta are potentially important TYLCTZV reservoirs because they occur in abundant numbers within the tomato farms, they are associated with whitefly vectors, and were found naturally infected with TYLCTZV.
