n African Entomology - Preliminary attempts to identify pathogens as biological control agents against species (Solanaceae) in South Africa




In 2008, a field survey was conducted in northern Argentina to collect natural enemies of species (Solanaceae) for use as biological control agents in South Africa. The rust fungus Bertero ex Mont. (Pucciniales: Pucciniaceae) was found on L'Hér. and imported into quarantine facilities in South Africa. No damaging pathogens were found on Schltdl. Preliminary host-range studies showed that was able to infect and cause disease on and on (Brongn. ex Neumann) Schltdl. in South Africa, and could have potential for the biological control of these species. The rust did not infect any of the other species tested, and neither did it infect which is the most problematic species in South Africa.
