Endophytic Actinomycetes As Potential Agents To Control Common Scab Of Potatoes, Alaxandra A. Goodman

All NMU Master's Theses

Potato marketability and tuber quality can be decreased upon infection by a pathogen, Streptomyces scabies. Current disease control consists of expensive irrigation systems and using hazardous chemicals, which exert limited disease control and are potential hazards to those exposed. Biological control offers a cost effective method for controlling disease. Antibiotic producing Streptomyces have indicated their ability to combat plant diseases. Some Streptomyces species colonize within plant tissues without causing disease symptoms (endophytes). This research sought for the presence of endophytic Steptomyces or closely related species in potato plants that were grown in fields containing pathogen-inhibiting Streptomyces. To establish genus …
