Ragweed, common ragweed, Upright ragweed, short ragweed (English), Ambrosia arteriosclerosis / Ambrosia elation (Latin) are all names for one and the same plant.
The Upright ragweed Koestler belongs to the family (Easterner) and is native to North America. The annual plant reaches a size between 30 to 150 cm and blooms from July to October, with finger-shaped, greenish-yellow buds that can produce up to one billion pollen grains per plant.
Ragweed pollen can trigger severe hay fever symptoms up to allergic asthma, allergic skin reactions can also occur on contact with the plant. In patients with allergic reactions to the Commons mug wort (Artemis vulgarism) can cross react with ragweed plants caused.
The ragweed pollen usually occur from July to October.
The spread of ragweed is particularly encouraged by human activities. Therefore, countermeasures and are consistent with a comprehensive education of the public health risk should be kept as low as possible.
The introduction of ragweed occurs in different ways. A major risk is from contaminated feed, seeds (eg sunflower seeds contaminated), and especially of bird feed from. This allows the plant to settle quickly without being noticed in private gardens. From here they can, by spreading the seeds, spread further in open areas.
The plant is found in bird feeding grounds in private gardens, along roads and paths, along railway lines and wasteland populated areas such as construction debris or places. The ragweed requires good lighting conditions and therefore free populated areas on heavily vegetated areas are not germinate the seeds.
Recommendations to combat ragweed
In May to August, gardens regularly for the presence of Ambrosia, particularly in areas where birds feed was used (Ambrosia seeds in bird seed mixes).
Buy bird food, and use that is not polluted with ragweed seeds. When shopping, you should specifically ask for it.
Ragweed is an annual, therefore, the production of long-lived seeds are prevented: It is safe to strip the plant by the roots before flowering (with gloves). Form new plants cut flowers.
The risk of allergic sensitization is higher in a repeated removal of large populations of flowering plants. It can occur while high concentrations of pollen in the air. A mouth guard is recommended, in addition, a tight-fitting full-vision goggles protect the eye conjunctiva.
The elimination of blooming ragweed stocks should take place in the afternoon, as the main pollen to be released into the morning hours.
Allergy sufferers should not perform these tasks themselves.
Stripped plants packed in plastic bags into municipal garbage, not compost the plants.
In later discovery can not be mowed until the beginning of seed production (around the beginning of September). Then no more, because this can increase seed dispersal.
If possible, open floor areas planted immediately.
Larger collections should be reported to the competent authorities: eg. Parks Commission, Environmental Protection Agency, plant protection services or Federal Biological Research Centre for Agriculture and Forestry BBA).
