Selection of Fungal Strains for Biological Control of Important Weeds in the Krasnodar Region of Russia. International Symposium on Biological Control of Weeds. Interpretive Summary:
Technical Abstract: Fungi, collected in different districts of the Krasnodar Region of the Russia Federation, were collected and isolated from diseased weed samples. Weeds sampled included species in the genera Centaurea, Salsola, Vincetoxicum, Carduus, Cirsium, and Echinochloa. Fungal isolates were selected based on biological tests and the potential of the fungi for classical and/or inundative biological control of the weeds. A live collection of plant pathogens, isolated from the collected herbarium material, was formed. This collection consists of the following genera isolated from Centaurea solstitialis and Centaurea diffusa: Acremonium kiliense, Alternaria alternata, A.radicina, A.brassicae, Aspergillus, Cladosporium, Coniochaeta, Embellisia chlamydospora, Epicoccum sp., Fusarium culmorum, F.heterosporum, F.oxysporum, F.sporotrichioides, Humicola sp., Periconia igniaria, Phoma sp., Rhizoctonia, Sclerotinia, Sordaria, Ustilaginoides ochracea, Verticillium dahliae,. The facultative fungi Periconia igniaria E.W. Mason et M.B. Ellis (Teleomorph Didymosphaeria igniaria C. Booth) and Phoma glomerata (Corda) Wollenw. et Hochapfel., and the obligate pathogen Puccinia hieracii var. hieracii (syn. P. jaceae) represented the greatest interest as potential agents for biological control of Centaurea solstitialis.
