It also infects many perennial weed species that can act as virus reservoirs for susceptible agricultural crops. These weed species include "Solanum nigrum" (nightshade), "S. aculeatissimum" (soda apple), "Chenopodium album" (pigweed), "Datura stramonium" (jimson weed), "Linaria canadensis" (blue toadflax), and "Physalis spp." (ground cherry). Thus, recommendations for the control of this virus include the control of weeds in and around susceptible solanaceous crops.
