“…The main meteorological factors affecting the rate of decomposition of straw, and the displacement of Fusarium species from that straw, are temperature and water availability (Lakhesar et al, 2010a). The decline in recovery of F. graminearum from straw pieces follows an exponential decay function of thermal time adjusted for rainfall.…”

Fusarium head blight (FHB) of wheat, caused mainly by a few members of the Fusarium graminearum species complex (FGSC), is a major threat to agricultural grain production, food safety, and animal health. The severity of disease epidemics and accumulation of associated trichothecene mycotoxins in wheat kernels is strongly driven by meteorological factors. The potential impacts of change in climate are reviewed from the perspective of the FGSC life cycle and host resistance mechanisms influenced by abiotic pressures at the ecological, physiological and molecular level. Alterations in climate patterns and cropping systems may affect the distribution, composition and load of FGSC inoculum, but quantitative information is lacking regarding the differential responses among FGSC members. In general, the coincidence of wet and warm environment during flowering enhances the risk of FHB epidemics, but the magnitude and direction of the change in FHB and mycotoxin risk will be a consequence of a multitude of effects on key processes affecting inoculum dynamics and host susceptibility. Rates of residue decomposition, inoculum production and dispersal may be significantly altered by changes in crop rotations, atmospheric carbon dioxide concentration ([CO2]), temperature and precipitation patterns, but the impact may be much greater for regions where inoculum is more limited, such as temperate climates. In regions of non-limiting inoculum, climate change effects will likely be greater on the pathogenic rather than on the saprophytic phase. Although the mechanisms by which abiotic stress influences wheat defences against Fusarium species are unknown, available data would suggest that wheat may be more susceptible to Fusarium infection under future climate conditions. Additional research in this area should be a priority so that breeding efforts and climate resilient management strategies can be developed.

“…It is therefore a very popular tool for analysing data that arise in many scientific disciplines, for instance biology (e.g., Soares et al 2011, Juliá and Peris 2010, Camargo et al 2011, biomedical and medical sciences (e.g., Camacho et al 2010, Oliboni et al 2011, earth sciences (e.g., Fontana et al 2010, Rangel et al 2011, social sciences (e.g., Conte et al 2011), economics (e.g., Misztal 2011), ergonomics (e.g., Bin andRichardson 2010, Zadry et al 2011), and of course agriculture (e.g., Chełkowski et al 2000, Cheng et al 2010, Lakhesar et al 2010, Bandehagh and Hossein Zadeh Moghbeli 2011, Cherati et al 2011, Heidari Zooleh et al 2011, Herrero et al 2011, Kesavacharyulu et al 2011, Rogiers et al 2011.…”

This paper discusses a number of aspects concerning the analysis, interpretation and reporting of correlations in agricultural sciences. Various problems that one might encounter with these aspects are identified, and suggestions of how to overcome these problems are proposed. Some of the examples presented show how mistaken and even misleading the interpretation of correlation can be when one ignores simple rules of analysis.

“…This takes place in a monocyclic occurrence from the spore repositories on the soil surface directly onto the wheat heads. The level of infection highly depends on the year and location and is also largely influenced by weather conditions (Lemmens et al 2004;Lori et al 2009;Lakhesar et al 2010).…”

Wheat (Triticum aestivum L.) is an important cereal crop in Kosovo and a major component of population food. Fusarium head blight (FHB) of wheat is an economically very significant disease. FHB leads to various losses in quality like reduced germination of seeds, reduced baking quality and reduced nutritional quality through mycotoxin contamination. In 2010 and 2011 the incidence and identity of the Fusarium spp. infecting wheat in Kosovo as well as mycotoxin contamination was investigated. The results of two years research work show that the incidence of FHB on winter wheat in 2010 was low (<6%). In the year 2011 the disease incidence was clearly higher (up to 31%). Based on morphological characters, F. graminearum was the most frequently Fusarium sp. identified on wheat kernels in the year 2010 (100%) and 2011 (98%). Less frequently isolated species included F. cerealis (<1%) and F. avenaceum (<1%). Wheat flour samples were analyzed by liquid chromatography coupled to mass spectrometry and found to be contaminated with a variety of mycotoxins, most importantly deoxynivalenol and zearalenone. This is the first report on the incidence as well as on the identification of Fusarium species isolated from naturally infected winter wheat in Kosovo.
