A biophysical and economic evaluation of biological and chemical control methods for Solanum elaegnifolium (Silverleaf Nightshade) in the Limpopo province, South Africa

The results showed that the difference in the weed density was insignificant, indicating that biological and chemical control were both effective in the management of S. elaeagnifolium. However biological control was shown to be more economically beneficial than chemical control, since there was a net gain as a result of lower costs using L. texana beetles. Further research is needed to determine the effectiveness of L. texana and damage caused by S. elaeagnifolium on expected yield to conduct a full cost-benefit analysis.
