Allergenic invasive plant <i>Ambrosia artemisiifolia</i> L. in Poland: threat and selected aspects of biology

The Asteraceae family is one of the largest families, comprising 67 genera and 264 species in Poland. However, only a few genera, including Artemisia and Ambrosia are potential allergenic sources. The aim of the study was to estimate how often and to what degree Artemisia and Ambrosia pollen seasons co-occur intensifying human health risk, and how synoptic situations influence frequency of days with high pollen concentrations of both taxa. Artemisia and Ambrosia pollen data were collected, using the volumetric method, at 8 sites in Poland. Daily concentrations of Artemisia pollen equal to 30 grains or more and Ambrosia pollen equal to 10 grains or more were accepted as high values. Concentrations of more than 10 pollen grains were defined as high in the case of Ambrosia because its allergenicity is considered higher. High concentrations were confronted with synoptic situations. Analysis was performed on the basis of two calendars on circulation types of atmosphere in Poland (Niedźwiedź, 2006, 2015). Co-occurrence of Artemisia and Ambrosia pollen seasons is being found most often, when Ambrosia pollen season starts in the first half of August. If it happens in the last 10 days of August high pollen concentrations of Artemisia and Ambrosia do not occur at the same days. At three sites (Sosnowiec, Rzeszów, Lublin) high Ambrosia pollen concentrations during the Artemisia pollen season appear more often than in other sites under question. The high Artemisia pollen concentrations occur, when continental or polar maritime old air masses inflow into Poland. The impact of air masses on high Ambrosia pollen concentrations depends on site localizations. It is likely, that in the south-eastern part of Poland high Ambrosia pollen concentrations result from the pollen transport from east-south-south-westerly directions and the local sources. Co-occurrence of both taxa pollen seasons depends on the air masses inflow and appears more often in a south-eastern part of Poland.

“…Regrowth of ragweed after mowing is well-documented (Barbour and Meade 1981, Bohren et al 2005, Bohren et al 2008, Meiss et al 2008, Karrer et al 2011, Patracchini et al 2011, Simard and Benoit 2011, Tokarska-Guzik et al 2011) and varies with season (Milakovic et al 2014b). Timing and frequency of cutting has specific influences on the seed production of ragweed (Simard andBenoit 2011, Milakovic et al 2014a).…”

NeoBiota 28: 39-49. doi: 10.3897/neobiota.28.6838 Abstract Ambrosia artemisiifolia is an invasive annual herb infamous for the high allergenicity of its pollen, which is related to increasing medical costs. Additionally, it can cause serious yield losses as agricultural weed. Common ragweed seeds accumulate in the soil and can remain therein viable for decades, which poses a problem for the sustainable management of these populations. A long term management should thus target a reduction of the soil seed bank. We observed the influence of four different mowing regimes on the ragweed soil seed bank at six roadside populations in eastern Austria. The mowing regimes were based on methods from common roadside management practice and specifically adapted to reduce seed production. After three years of application, the soil seed bank was indeed reduced by 45 to 80 percent through three of the four mowing regimes tested. Therefore, we suggest that the best mowing regime for the most effective reduction of the size of the soil seed bank is the one consisting of one cut just after the beginning of female flowering (around the 3 rd week of August in Eastern Central Europe), followed by a second cut 2-3 weeks later.

“…Galzina et al (2013) gathered comprehensive distributional data on the species in Croatia and reported its presence in crop fields and urban and peri-urban areas. Comprehensive distributional data (mostly based on herbarium specimens) were gathered in other European countries or regions, e. g. Austria, Poland, and Serbia (Csontos et al 2010;Tokarska-Guzik et al 2011). Recent studies have predicted its current and future distribution across Europe (Cunze et al 2013).…”
