Estimates of
Common Ragweed Pollen Production for Urban Ragweed Plants.
Seeds of
common ragweed were sown in soil in an unheated greenhouse at the Institute of Plant Protection, Hunan Academy of Agricultural Sciences, Changsha, China (25.354947[degrees]N, 114.56111[degrees]E).
Here, we quantify the potential consequences of climate change on pollen allergy, focusing upon the annual herbaceous plant
common ragweed (Ambrosia artemisiifolia) in Europe (henceforth referred to as ragweed).
Acuron offers broad-spectrum control of more than 70 weeds in corn, including giant ragweed,
common ragweed, Palmer amaranth, waterhemp, marestail, kochia, cocklebur, morningglory and Russian thistle.
Common ragweed can readily produce a million pollen grains per plant per day, and it floats for hundreds of miles or more.
Anglers coming into contact with giant hogweed have received skin inflammations, while the pollen of
common ragweed causes asthma.
Anglers coming into contact with giant hogweed, another species alien to Britain, have been left with painful swelling and rashes, while the pollen of
common ragweed causes asthma.
Species which are already in the UK and causing problems include
common ragweed, which came in to Europe from North America in grain mixes intended as bird feed and is a potent trigger for hayfever and other allergies.
An international team of scientists will kickstart the EU-funded study - the first of its kind and costing some 3.5million euros - by focusing on the spread of Ambrosia artemisiifolia, more widely known as
