The pollen season is drawing to a close, but fungal spores remain a problem!

Most herbaceous, allergen-producing plants have already finished flowering. Only a few scattered specimens of ragweed, mugwort, grasses, stinging nettles and plantain can still be found in bloom. This trend is also evident at our monitoring station in Feldkirch. This trend is also evident at our monitoring station in Feldkirch. Fungal spore concentrations will continue to fluctuate between moderate and high levels over the coming days.

As mentioned, the flowering season for local ragweed populations is over. However, long-distance transport from our western neighbouring countries may cause low to moderate levels of exposure for sensitised individuals, particularly on Thursdays and Fridays, as even a few pollen grains per cubic metre of air are sufficient to trigger symptoms. 

Canadian goldenrod is also still in flower in Vorarlberg. It can cause cross-reactions in people with allergies who are sensitive to mugwort or ragweed. People with allergies should avoid dense stands of this plant.
