Interpretive Summary:

Technical Abstract: Salsola tragus (Russian thistle, Chenopodiaceae) is a major weed pest in the western United States. An isolate of the rust fungus Uromyces salsolae from the Yasensky Spit in Russia is currently under evaluation as a candidate for biological control of S. tragus in a Biosafety Level 3 (BL-3) containment greenhouse facility. The life cycle of U. salsolae has been completed in greenhouse studies, demonstrating that it is macrocyclic and autoecious on Russian thistle. Plant inoculations were made with spores from each stage in the fungus life cycle, demonstrating their viability and role in the life cycle. Data will be included in a risk assessment of U. salsolae for biological control of S. tragus.
