“…Using an insect vector, such as the weevil C. onopordi , is another way that researchers have attempted to mimic natural processes. This has been successful in field trials in Europe with higher infection percentages being achieved with insect vectors than solely applying urediniospores or teliospores 73–75 …”

Californian thistle (Cirisum arvense) is a troublesome weed in pastures and cropping systems. The fungal biocontrol agent Puccinia punctiformis, commonly referred to as thistle rust, performs inconsistently on C. arvense. Problems with P. punctiformis establishment and control of C. arvense may be attributable to differing plant endophytic populations in various environments. This article provides an overview of the relationships between endophytes and their host, but also between endophytes and pathogens with a focus on rust pathogens. This review provides insights into reasons why P. punctiformis performs inconsistently and identifies gaps in our knowledge. Filling these gaps may help to improve performance of this classical fungal biocontrol agent. © 2023 The Authors.

“…The importance of these observations for a possible control of C. arvense was recognized by Cockayne (1915) and Ferdinandsen (1923). Later studies were carried out attempting to stimulate spore germination (French et al 1988, French 1990, French and Lightfield 1990, Frantzen 1994, to artificially spread spores in order to obtain higher infection rates (Thomas et al 1994, Guske et al 2003, Kluth et al 2003, Demers et al 2006, Wandeler and Bacher 2006, Müller et al 2011 and studying interactions between P. punctiformis and insects (Friedli and Bacher 2001a, Kluth et al 2001, Kluth et al 2002, Cripps et al 2009. Puccinia punctiformis causes two different kinds of infections, local and systemic infections.…”

“…While local infections cause only small lesions on thistle leaves and influence the plant's performance only marginally (Kluth et al 2005), systemic infections usually kill the infected shoots within a few months, mostly before flowering (French and Lightfield 1990). Most studies were unable to reach higher rates of systemic infection than 20 to 50% by artificial inoculation (e.g., Van den Ende et al 1987, French et al 1988, Frantzen 1994, Wandeler and Bacher 2006, Müller et al 2011. This is considered inadequate for a successful suppression of C. arvense (Van den Ende et al 1987, Van Leest andScheepens 1994).…”

Plant pathogens as biocontrol agents of Cirsium arvense – an overestimated approach?

Cirsium arvense is one of the worst weeds in agriculture. As herbicides are not very effective and not accepted by organic farming and special habitats, possible biocontrol agents have been investigated since many decades. In particular plant pathogens of C. arvense have received considerable interest and have been promoted as “mycoherbicides” or “bioherbicides”. A total of 10 fungi and one bacterium have been proposed and tested as biocontrol agents against C. arvense. A variety of experiments analysed the noxious influence of spores or other parts of living fungi or bacteria on plants while others used fungal or bacterial products, usually toxins. Also combinations of spores with herbicides and combinations of several pathogens were tested. All approaches turned out to be inappropriate with regard to target plant specificity, effectiveness and application possibilities. As yet, none of the tested species or substances has achieved marketability, despite two patents on the use of Septoria cirsii and Phomopsis cirsii. We conclude that the potential of pathogens for biocontrol of C. arvense has largely been overestimated

Tracing the origins of White Tip disease of Cirsium arvense and its causal agent, Phoma macrostoma

et al. 2012

Summary Cirsium arvense (Asteraceae) is known as creeping thistle in its native range in the UK and Canada thistle in its invasive North American range. Recently, the fungus Phoma macrostoma was registered in Canada as a bioherbicide in turfgrass, where it causes severe chlorosis (White Tip disease) and death of C. arvense and other broadleaved weeds. It was hypothesised that the disease originated in the UK on its thistle host and, therefore, that fungal isolates from both countries should be biologically and genetically similar. Twenty‐six strains in the genus Phoma– isolated during surveys in the UK – were compared morphologically with the type culture of P. macrostoma, tested for bioherbicidal activity using the inoculum mat bioassay and genetically screened with bioherbicide‐specific primers. White tip disease was found to be restricted to the eastern and southern counties of England. Phoma macrostoma was isolated consistently from diseased bleached tissues. Bioherbicidal isolates of P. macrostoma occupy a unique clade, which is phylogenetically distinct but morphologically indistinguishable from the type culture. Most isolates from the UK had the same bioherbicidal activity and similar genetic make‐up as strain SRC 94‐44B, the active ingredient in the registered Canadian product. The origin of all bioherbicidal strains found to date has a clear presence in both Canada and the UK, with strong genetic similarities, supporting the view of a common ancestry. Thus, on the evidence presented, the ‘white tip’ clade of P. macrostoma evolved in southern England. Therefore, the bioherbicide based on strain SRC 94‐44B should also be eligible for registration in the UK, based on the pest risk assessment data already available.
