“…For example, in New Zealand, Allen (5) reported that the native barberry species was resistant to stem rust, but recent surveys show that susceptible Berberis species exist in this region (129). In Africa, aeciospores from naturally infected B. holstii plants were inoculated on cereal hosts but failed to infect these hosts because of nonviable spores; however, some aecia were identified as Pgt using molecular markers (75).…”

Cereal rusts, caused by obligate and biotrophic fungi in the genus Puccinia, are important diseases that threaten world food security. With the recent discovery of alternate hosts for the stripe rust fungus (Puccinia striiformis), all cereal rust fungi are now known to be heteroecious, requiring two distinct plant species serving as primary or alternate hosts to complete their sexual life cycle. The roles of the alternate hosts in disease epidemiology and pathogen variation vary greatly from species to species and from region to region because of different climatic and cropping conditions. We focus this review on rust fungi of small grains, mainly stripe rust, stem rust, leaf rust, and crown rust of wheat, barley, oat, rye, and triticale, with emphases on the contributions of alternate hosts to the development and management of rust diseases.

“…Existing use of wind model information has already provided useful indications of likely migration routes for the ''Ug99'' lineage. Initial predictions made in 2005-2006(Hodson et al 2005Singh et al 2006) have largely been supported by subsequent field observations. Additional climate-based disease suitability models will be evaluated and included if shown to provide reliable value-added information at the national or regional scale.…”

Surveillance of wheat rust pathogens, including assessments of rust incidence and virulence characterization via either trap plots or race (pathotype) surveys, has provided information fundamental in formulating and adopting appropriate national and international policies, investments and strategies in plant protection, plant breeding, seed systems, and in rust pathogen research. Despite many successes from national and regional co-ordination of rust surveillance, few attempts were made to extend rust surveillance to international or even global levels. The Global Cereal Rust Monitoring System was established to address this deficiency. It is underpinned by an information platform that includes standardized protocols for methods and systems used in surveys, preliminary virulence testing, data, sample transmission and management at the field and national and global levels, and includes two web-based visualization tools. While considerable progress has been made towards a global system for monitoring variability in the wheat stem rust pathogen, and linking this to the threat posed by this pathogen to regional wheat production, some challenges remain, including ongoing commitment to support rust surveillance, and the ability to share and compare surveillance data.

“…A dissecting microscope was used to search necrotic areas for diagnostic reproductive structures of fungi. Methods outlined previously (Waipara et al 2005) were used to isolate fungi from diseased tissues. Small pieces of tissue (174 in total) were cut from the leading edge of diseased areas and surface sterilised.…”

Moth plant Araujia sericifera is an environmental weed in northern regions of New Zealand Due to its rapid spread its ability to cause substantial damage to natural ecosystems and the increasing cost of conventional control methods a biological control programme was initiated A survey of the plant in New Zealand found that damage attributed to either disease or insect herbivory was minimal with little biocontrol potential Botanical pathogen and insect surveys were subsequently initiated in the native South American range to locate and identify potential agents for classical biocontrol Potential agents associated with plant damage were collected Damage was mostly due to pathogenic attack with 90 of moth plant populations showing disease symptoms To date eight fungal pathogens have been associated with plant die back leaf necroses and a severe fruit rot At least two mosaic (virus) diseases were also found frequently associated with colonies of the aphid Aphis nerii
