“…However, the incidence and severity of the disease has increased substantially in recent years and yield losses of up to 80% were reported in the susceptible mungbean cultivars (Kelly, 2017). Outbreaks and spread of diseases were reported in other legume crops, such as soybean (Sconyers et al, 2006) and chickpea . For example, Asian soybean rust (Phakospora pachyrhizi) was a problem in Asia and South America, but then spread rapidly across eight states of southeastern United States within a few years of first detection in Louisiana in 2004 (Sconyers et al, 2006).…”

“…Currently, the only effective control of ASR is through the use of single or sequential fungicide sprays depending on the disease pressure Levy, 2005;Sconyers et al, 2006), but long-term effectiveness may be reduced because of the considerable increase in production costs and the potential ineffectiveness of host resistance under high ASR pressure, as well as the variable efficiency of the different fungicides . Current soybean cultivars lack in resistance or tolerance to reduce damage by ASR and cultural practices have proven to be limited for managing the disease (Yorinori et al, 2005).…”

Favorable meteorological and environmental conditions are critical components that affect Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, the most damaging fungal disease of soybean. In this review, we used available knowledge on the effect of meteorological factors affecting the disease to construct a systems-based approach to understand the risk of ASR epidemics. The systems approach is based on a hierarchical framework where relevant environmental factors that affect the key stages of the ASR disease cycle are identified and this included both aerobiological and epidemiological components. The formal framework we used examined the following epidemic characteristics: spore release, spore dispersal, spore deposition, infection efficiency, latent period and spore production. It provided the ability to identify the most important meteorologicalrelated factors along with relevant knowledge gaps from which the implications for disease forecasting were described. This is new information that can be used as a guide for further epidemiological research and especially to develop and improve upon both local and regional risk models. Key words: Phakopsora pachyrhizi, plant epidemiology, risk prediction, climatology, plant diseases FATORES METEOROLÓGICOS E AS EPIDEMIAS DE FERRUGEM ASIÁTICA -UMA ABORDAGEM SISTÊMICA E IMPLICAÇÕES NA AVALIAÇÃO DE RISCORESUMO: Condições meteorológicas e ambientais são componentes críticos nas epidemias de ferrugem asiática da soja (FAS), doença causada pelo fungo Phakopsora pachyrhizi e que causa o maior dano na cultura da soja. Nesta revisão, o conhecimento sobre o efeito de fatores meteorológicos que influenciam nas epidemias foi usado para construir uma abordagem sistêmica para compreender o risco de epidemias de FAS. Esta é baseada em uma estrutura hierárquica onde os fatores relevantes que afetam os estágios chave no ciclo da doença foram delineados, incluindo os componentes aerobiológicos e epidemiológicos. As seguintes características epidemiológicas foram avaliadas: liberação de esporos, dispersão de esporos, deposição de esporos, eficiência de infecção, período latente e produção de esporos. O conhecimento sobre os fatores meteorológicos que afetam cada um dos componentes foi revisado, sendo identificados os fatores mais importantes e as falhas de conhecimento, bem como as implicações para a previsão da doença. A informação é importante para orientar a pesquisa epidemiológica futura e especialmente desenvolver e melhorar modelos de risco da doença em níveis locais a regionais.

“…Considering only the epidemic on soybean, the disease expanded at an average rate of 8.8 and 10.4 km day -1 in 2005 and 2006, respectively, resulting in limited regional spread of soybean rust (Christiano and Scherm 2007). This limited spread may be the result of slow disease progress on kudzu (Christiano and Scherm 2007;Jordan et al 2010;Young et al 2011a) combined with the short window for disease establishment on soybean that occurs primarily during its reproductive growth stages (Christiano and Scherm, 2007;Dorrance et al 2008;Sconyers et al 2006); or it may be a result of low inoculum availability in 2005 and unusually dry conditions in 2006 (Christiano and Scherm, 2007). The situation may have been very different in 2005, which was a very active tropical storm and hurricane year (https://www.tropicalweather.net).…”

From Select Agent to an Established Pathogen: The Response to Phakopsora pachyrhizi (Soybean Rust) in North America

et al. 2015

The pathogen causing soybean rust, Phakopsora pachyrhizi, was first described in Japan in 1902. The disease was important in the Eastern Hemisphere for many decades before the fungus was reported in Hawaii in 1994, which was followed by reports from countries in Africa and South America. In 2004, P. pachyrhizi was confirmed in Louisiana, making it the first report in the continental United States. Based on yield losses from countries in Asia, Africa, and South America, it was clear that this pathogen could have a major economic impact on the yield of 30 million ha of soybean in the United States. The response by agencies within the United States Department of Agriculture, industry, soybean check-off boards, and universities was immediate and complex. The impacts of some of these activities are detailed in this review. The net result has been that the once dreaded disease, which caused substantial losses in other parts of the world, is now better understood and effectively managed in the United States. The disease continues to be monitored yearly for changes in spatial and temporal distribution so that soybean growers can continue to benefit by knowing where soybean rust is occurring during the growing season.
