“…Following Picco (1992), this may be due in part to nutritional or toxic antagonistic interactions that B. cinerea exert on the other two fungal species. Earlier studies have highlighted the abundance of B. cinerea spores in comparison with U. necator and P. viticola spores in the same vineyard (Albelda et al, 2005;Fernández-González et al, 2009) or in various Galician areas (Díaz et al, 1997(Díaz et al, , 1998Rodríguez-Rajo et al, 2002). Likewise, the vulnerability of grapevine to pathogenic attack depends to a large extent on the phenological stage at which the attack takes place, on the pathogen involved, and on prevailing weather conditions.…”

“…The ideal conditions for U. necator infection coincide with the period from 'beginning of flowering' to the time at which berries attain a diameter of 7 mm (Campbell et al, 2007). Finally, 'flowering' and the beginning of 'development of fruits' are considered the most sensitive phases for P. viticola infection (Díaz et al, 1997).…”

“…We can hypothesize that spores may have been transported from a distant source located in conditions more conducive to development and sporulation of B. cinerea (South of Spain, North Africa for example). (Jarvis, 1962;Diaz et al, 1997Diaz et al, & 1998Blanco et al, 2006;Rodriguez-Rajo et al, 2010;Fernandez-Gonzalez et al, 2011). One possible explanation for the low values of our study could stem from the fact that our air sampler was not localized in the vicinity of diseased crops.…”

“…Quantitative studies on airborne B. cinerea inoculum have been conducted during the growing season of several major susceptible crops such as grapes in North-West Portugal (Oliveira, 2009) and North-West Spain (Diaz et al, 1997 and1998;Rodriguez-Rajo et al, 2010;Fernandez-Gonzalez et al, 2011) or strawberry in South-West Spain (Blanco et al, 2006). Spore sampling was realized in the air above or near susceptible crops during the development of grey mould epidemics (Diaz et al, 1997;Blanco et al, 2006;Decognet et al, 2009).…”

Airborne inoculum of Botrytis cinerea was monitored bimonthly during three years (Sept. 2007-Dec. 2010) on a site in the South-East of France located approximately 5 km away from susceptible crops.Viable inoculum was collected for 96% of the sampling days, including during cold winter periods and hot and dry summer conditions. The concentration of airborne inoculum was significantly higher during daytime than at night. Peaks of concentration were recorded at different periods each year (Sept-Oct in 2008, May in 2010. The abundance of viable inoculum was positively correlated with average daily relative humidity and negatively correlated with air temperature and solar radiation. The analysis of backward trajectories suggested that air masses originating from the North or the South brought more viable inoculum than those from the West. This study showed that susceptible crops may be at danger from viable inoculum of B. cinerea during all seasons of the year, but that risk prediction models could be developed on the basis of climatic conditions and the origin of air masses.

The aim of the study was to determine seasonal variation in concentrations of selected fungal spore types due to meteorological parameters. The presence of spores of thirteen taxa: Cladosporium, Torula, Alternaria, Botrytis, Epicoccum, Stemphylium, Ganoderma, Erysiphales, Entomophthora, Drechslera type, Didymella, Polythrincium and Pithomyces was recorded in Cracow using a Burkard trap. The majority of selected taxa belong to the anamorphic fungi group, the others to Ascomycetes, Basidiomycetes and Zygomycetes. Fungal spores were present in the air in large numbers throughout the summer with the highest levels being reached in June, July and August although their highest concentrations differed with time. For most of the studied spore types: Botrytis, Ganoderma, Alternaria, Epicoccum, Torula, Drechslera type, Polythrincium, Stemphylium and Pithomyces the peak period was recorded in August. Didymella and Entomophthora spores reached their highest concentrations in July while concentrations of Erysiphales and Cladosporium spores were highest in June. Multiple regression analysis was performed for two seasonal periods: pre-peak and post-peak. In the pre-peak period concentrations of 10 spore types: Cladosporium, Botrytis, Epicoccum, Stemphylium, Drechslera type, Pithomyces, Didymella, Erysiphales, Ganoderma and Entomophthora were strongest influenced by minimum temperature while Alternaria, Polythrincium and Torula by maximum temperature (significance level of a ¼ 0.05). During the post-peak period the most important factor affecting variation in concentrations of Botrytis, Polythrincium, Didymella, Erysiphales, Ganoderma and Entomophthora spores was the minimum temperature. For Alternaria, Cladosporium, Epicoccum and Torula the maximum temperature appeared to be the most influential, whereas for Drechslera type, Stemphylium and Pithomyces it was sunshine. All correlations between spore concentration, minimum and maximum temperature and sunshine were significant (significance level of a ¼ 0.05), and positive although the percentage of explained variation (R 2 ) was low.
