Health risk from Hercules perennial - City relies on targeted control in paths and frequented areas
The giant hob, also known as Herculesa (Heracleum Mantegazzianum), is currently again ensuring numerous reports in Riedstadt. Via the urban service portal, increasingly refer to new locations. The environmental group is informed about the occurrences - the control measures are already in full swing.
The plant, which is up to four meters high, originally comes from the Caucasus and was introduced to Europe in the 19th century. Since then it has spread greatly - first along water, now far beyond. Your enormous seed production - a single plant can form more than 50,000 seeds - favors the spread.
Health risk from Furanocumarine
The giant hogweed for human health is particularly dangerous: the plant juice contains so-called furanocumarins , which can cause severe skin irritation and burns under sunlight. Contact with the plant can already lead to bladder formation and inflammatory reactions - in severe cases, even injuries to third degrees possible. Protective clothing is mandatory for every touch. In the event of skin contact, it should be rinsed with lots of water immediately and medical help should be consulted if necessary.

Combating with limited funds
In Riedstadt, fighting focuses on heavily frequented areas and paths. This is where machines such as mulch devices are used, coordinated by Gerry Assmann from the Environmental Group. It is supported by the building yard and farmers. In contrast, effective control is hardly possible in difficult areas or further remote areas.
The plant is particularly resistant and keeps running out - a permanent pushing back is therefore very difficult. The most important measure remains to prevent seed formation , which requires repeated control courses.
Well-known occurrence in Riedstadt can be found in the Altneckarbett on Scheid-, Hohlgraben and Sandbach , on the Altrhein in Erfelden and near the courtyard of water biblos . The city asks citizens for attention and at the same time informs about the dangers.
