“…Puccinia lagenophorae (Cooke) is a rust fungus found extensively in Australia and Europe on S. vulgaris and several other weeds (Wilson et al 1965). It was isolated recently from S. vulgaris plants in the Salinas Valley in California (Scholler and Koike 2001).…”

Territories. High fecundity, rapid wind dispersal, continuous germination under a wide range of growing conditions, rapid growth rate, ability to set seed a number of times per growing season and lack of chemical control options has made this species an important weed of some horticultural crops. This species produces pyrrolizidine alkaloids that have been implicated as a cause of liver toxicity in livestock. Populations of S. vulgaris have displayed resistance to Group 5, 6 and 7 herbicides (triazines, uracils, substituted ureas and nitriles) and other photosynthetic-transport-inhibiting herbicides. Triazine resistance in S. vulgaris was the first reported case of herbicide resistance worldwide. A rust pathogen, Puccinia lagenophorae Cooke, is currently being evaluated for control of S. vulgaris in Europe. L'espèce est devenue une importante adventice dans certaines cultures horticoles à cause de sa grande fertilité, de la dispersion rapide de ses graines par le vent, de son pouvoir de germination dans maintes conditions, de sa croissance accélérée, de sa capacité à produire plusieurs fois des semences pendant la saison végétative et du manque de moyens de lutte chimiques. L'espèce synthétise les alcaloïdes de la pyrrolizidine à l'origine de problèmes d'intoxication du foie chez les bovins. Les peuplements de S. vulgaris résistent aux herbicides des groupes 5, 6 et 7 (triazines, uracils, substituts de l'urée et des nitriles) et à d'autres désherbants qui inhibent le transport actif et la photosynthèse. La résistance de S. vulgaris à la triazine est le premier cas de résistance à un herbicide à avoir été signalé dans le monde. En Europe, on évalue actuellement l'utilité de la rouille Puccinia lagenophorae Cooke dans la lutte contre cette adventice.

“…McAlpine (1906) considered all taxa with more or less identical morphology and life cycle but occurring on different host plant genera in Australia as different species. Based on biometrical studies and inoculation experiments, Viennot-Bourgin (1964) and Wilson et al (1965) indicated that the species can neither be split into "morphological" nor into "biological" species. Consequently, Wilson et al (1965) combined them under the oldest name, Puccinia lagenophorae (type host species: Lagenophora billardierei Cass., tribe Asterae) within which were included P. allanii G.…”

Puccinia lagenophorae is a rust fungus originating from Australasia which has spread throughout the world. A phylogenetic analysis of taxa related to this species was performed using rDNA (LSU, ITS) sequence data. The analyses revealed a well-supported cluster including all specimens of P. lagenophorae. By evaluating morphological and sequence data, the species is taxonomically re-defined and a list of synonyms is provided. Puccinia distincta on Bellis perennis, a species recently separated from P. lagenophorae, P. saccardoi, a species on the Goodeniaceae, and P. byliana, a species so far only known from South Africa, are reduced to synonymy in P. lagenophorae, as are several other species. Our analysis indicates that P. lagenophorae is likely not derived from the northern hemisphere species P. obscura, but from a species from Australia host-alternating between Asteraceae (aecial host) and Cyperaceae/Juncaceae (telial host). Another related species, P. stylidii (on Stylidium sp., Stylidiaceae) may have been derived from the same parental species as P. lagenophorae. From ontogenetical and morphological studies, the presence of pycnia could not be confirmed in the life cycle of this species, and the width of the pedicel of teliospores at the point of attachment was found to be highly variable and not a taxonomic character. The number of known host species is approximately 150, including 41 new host plants recorded herein.

Classical biocontrol of Senecio jacobaea (ragwort) has generally utilised herbivorous insects, although the nisi Puccinia expansa has also been considered. Although this rust is specific and damaging in the glasshouse. It has not been used in the field. Research into the ecophysiology of Senecio vulgaris (groundsel) infected by the rust Puccinia lagenophorae has revealed the extent to which the effects of infection are dependent on environmental factors. The damage caused by rust is enhanced under mild drought conditions, during periods of frost in winter and by competition between groundsel and neighbouring plants, bui is reduced by nutrient deficiency. Rust injury is also greatly increased by secondary infection of pustules by necrotrophic fungi. Such secondary infection can be achieved artificially with a range of opportunistic necrolrophs and can selectively kill groundsel: the effective inoculum dose of both fungi is significantly reduced. Attempts to apply our understanding of rust‐necrotroph injury to ragwort have been partially successful but we have not succeeded in causing significant mortality of this host. This paper discusses these, and other weed—pathogen—environment interactions, and their possible application to biocontrol.
