“…Surveys of wheat yellow rust in five Egyptian provinces over the period 2018-2020 revealed 42 physiological races, with six new aggressive races detected in the study (Esmail et al 2021). Field response data indicated that of 15 wheat cultivars tested, only four showed moderate levels of resistance with known resistance genes.…”

A synoptic review of plant disease epidemics and outbreaks was made using two complementary approaches. The first approach involved reviewing scientific literature published in 2021, in which quantitative data related to new plant disease epidemics or outbreaks had been obtained via surveys or similar methodologies. The second approach involved retrieving new pest presence records added to the CABI Distribution Database in 2021. The literature review for the first approach had two stages. Stage 1 aimed to identify publications on plant diseases caused by pathogen taxonomic groups and led to retrieval of 99 core articles describing studies in 62 categories (pathogen species or species complexes) across more than 40 host species in 6 continents. In Stage 2, the core articles were augmented with further articles providing more context and information for the pathogen species identified in Stage 1. When both sets of articles were combined, the pathogen species with more than 5 articles were: Bursephalenchus xylophilus, Candidatus Liberibacter asiaticus, cassava mosaic viruses, citrus tristeza virus, Erwinia amylovora, Fusarium spp. complexes, Fusarium oxysporum f.sp cubense, Magnaporthe oryzae, maize lethal necrosis co-infecting viruses, Meloidogyne spp. complexes, Pseudomonas syringae pvs, Puccinia striiformis f.sp tritici, Xylella fastidiosa, and Zymoseptoria tritici. The automated search of the CABI Distribution Database led to 617 new distribution records from 283 plant pathogens in 2021 and was followed by manual review of all pathogens with more than 4 new records, to identify confirmed first reports in a new location. A total of 15 pathogens was identified: apple hammerhead viroid, apple rubbery wood viruses, Aphelenchoides besseyi, Biscogniauxia mediterranea, Ca. Liberibacter asiaticus, citrus tristeza virus, Colletotrichum siamense, cucurbit chlorotic yellows virus, Erwinia rhapontici, Erysiphe corylacearum, Fusarium oxysporum f.sp. cubense Tropical Race 4, Globodera rostochiensis, Nothophoma quercina, potato spindle tuber viroid, and tomato brown rugose fruit virus. Although 3 very important pathogens – Ca. Liberibacter asiaticus, citrus tristeza virus and Fusarium oxysporum f.sp cubense – were represented in the results of both approaches, in general the two approaches revealed distinct sets of plant disease outbreaks and new records, with little overlap in the results.

This work aimed to evaluate one hundred and fifty-five commercial wheat fields including six varieties of yellow rust (stripe rust) epidemics caused by Puccinia striiformis f. sp. tritici, in Gharbia governorate during the 2019 to 2021 seasons. Also, study the weather variables associated with yellow rust outbreaks in wheat. Temperature, relative humidity, and rain variables were obtained from the regional climate model imeto2 (http//meto.at/farmview/) as well as the World Climate Research Programme (WCRP) Global Energy and Water Cycle Experiment's (GEWEX) Surface Radiation Budget (NASA/GEWEX SRB) during the infection period from January to March. Results revealed that the high disease epidemic linked to rain precipitation and number of precipitation days combined with the minimum temperatures (5−10°C) and relative humidity (RH) of at least 60%. Levels of yellow rust severity varied according to the studied year, and wheat variety. Gemmeiza-11, Sids-12, Misr-1, and Misr-2 were the most susceptible varieties, while both Gemmeiza12 and Sakha95 were resistant to yellow rust disease during the studied period. In the 2021 season, all the wheat varieties showed a resistance response. The loss % ranged between 36.00, 40.00 %(Gemmeiza-11); 36.00, 37.25% (Sids-12); 25.00, 33.33% (Misr-1) and 21.21, 24.84% (Misr-2) in 2019 and 2020 growing seasons, respectively compared to the grain yield in 2021 season. Low disease severities were detected ranging from zero to trace infection (2.00%) in the 2021 season. A high and positive correlation coefficient (R 2 ) was found between disease severity % and loss in grain yield of the tested wheat varieties.

“…Examples include Sri Lankan cassava mosaic virus emerging in Southeast Asia (Charoenvilaisiri et al 2021), Xylella subspp in the Balearic Islands (Olmo et al 2021), citrus tristeza virus strains (Park et al 2021, Llanes-Alvarez et al 2021, Erwinia spp in the USA (Singh et al 2021), antibiotic resistance in Pseudomonas syringae pv actinidiae (Psa) (Lee et al, 2021), fungicide resistance in Zymoseptoria tritici (Garnault et al, 2021) (see detailed summaries in Electronic Supporting Information, S5). Many studies were concerned with the field performance and deployment of resistant varieties: such as for pokkah boeng disease in sugarcane (Shan et al 2021, Solic-Palacios et al 2021, wheat yellow rust (Perronne et al 2021, Esmail 2021. Fewer field studies were made on the use of biological control agents in disease management: such as for root knot nematode in vegetable crops (Sabri et al 2021), Psa in kiwi fruit (Ares et al 2021) (Electronic Supporting Information, S5).…”

A synoptic review of plant disease epidemics and outbreaks was made using two complementary approaches. The first approach involved reviewing scientific literature published in 2021, in which quantitative data related to new plant disease epidemics or outbreaks were obtained via surveys or similar methodologies. The second approach involved retrieving new records added in 2021 to the CABI Distribution Database, which contains over a million global geographic records of organisms from over 50,000 species. The literature review retrieved 186 articles, describing studies in 62 categories (pathogen species/species complexes) across >40 host species on 6 continents. Pathogen species with >5 articles were: Bursaphelenchus xylophilus, Candidatus Liberibacter asiaticus, cassava mosaic viruses, citrus tristeza virus, Erwinia amylovora, Fusarium spp. complexes, Fusarium oxysporum f. sp. cubense, Magnaporthe oryzae, maize lethal necrosis co-infecting viruses, Meloidogyne spp. complexes, Pseudomonas syringae pvs, Puccinia striiformis f. sp. tritici, Xylella fastidiosa, and Zymoseptoria tritici. Automated searches of the CABI Distribution Database identified 617 distribution records new in 2021 of 283 plant pathogens. A further manual review of these records confirmed 15 pathogens reported in new locations: apple hammerhead viroid, apple rubbery wood viruses, Aphelenchoides besseyi, Biscogniauxia mediterranea, Ca. Liberibacter asiaticus, citrus tristeza virus, Colletotrichum siamense, cucurbit chlorotic yellows virus, Erwinia rhapontici, Erysiphe corylacearum, Fusarium oxysporum f. sp. cubense Tropical Race 4, Globodera rostochiensis, Nothophoma quercina, potato spindle tuber viroid, and tomato brown rugose fruit virus. Of these, 4 pathogens had at least 25% of all records reported in 2021. We assessed two of these pathogens – tomato brown rugose fruit virus and cucurbit chlorotic yellows virus – to be actively emerging in/spreading to new locations. Although three important pathogens – Ca. Liberibacter asiaticus, citrus tristeza virus and Fusarium oxysporum f. sp. cubense – were represented in the results of both our literature review and our interrogation of the CABI Distribution Database, in general our dual approaches revealed distinct sets of plant disease outbreaks and new records, with little overlap.
