Abstract
Infective fourth stage larvae of the silverleaf nightshade (Nothanguina phyllobia Thorne) were broadcast on rangeland populations of silverleaf nightshade (Solanum elaeagnifolium Cav.) as a biological control for the weed. Plots were inoculated with nematode-infested dried leaves in April and August of 1977 at two southern High Plains shortgrass prairie locations. One site had been denuded of vegetation 2 years previously. While the August inoculation failed, the April inoculation was successful at both locations: 41% of the plants at the denuded site and 20% of the plants at the shortgrass site became infected with nematodes. At the disturbed site, a difference from the control of 23% in the foiiar biomass and a 42% in the plant density of silverleaf nightshade were attributable to nematode injury. Nematode infection was not observed on any other plant species.
