While this weed is dangerous to humans, experts remind. Its stems, leaves and fruits contain essential oil, rich in furanokumariny – substances which in contact with the skin can increase sensitivity to UV light. This leads to acute dermatitis occurring in the form of long non-healing burns. A minor hit of juice on the skin, as under the influence of light on the skin causing severe, painful burns with blisters filled with fluid.

the Main principle of combating Hogweed – not to allow to ripen seeds which are then spread by the wind. Once in the soil, they will germinate for several years.

the Fight with a single plant of Heracleum Rosselkhoznadzor specialists advised to conduct manual weeding, trimming the roots, cutting the aerial part. If we are talking about 100-1000 plants, it is better to use complex method: pruning of the roots, mowing the aboveground mass of a scythe or mowing, and chemical treatment.

And to deal with large populations (over 1000 plants) require special equipment for the plowing. The roots of the plants are cut and crushed and its growth slows down. “Plowing to a depth of 25 cm or more moves cut the root system of the weed from the bottom layers to the top. This breaks the contact of plants with soil, and, therefore, is limited to power plants, leading to depletion and destruction,” says the Rosselkhoznadzor.

After that, it is recommended to sow perennial grasses (red fescue, perennial ryegrass, Kentucky bluegrass). They prevent the penetration of light to the Hogweed is its competition.

At the same time to apply chemical treatment with herbicides. Getting on the leaves of the weed and once inside, they move through the vascular system and cause the death of not only its aerial parts, but also damage the roots. The evaluation of the Rosselkhoznadzor, the most effective in combating Hogweed can be considered as a tank mix based on the Isopropylamine salt of glyphosate acid and dimethylamine of salt. It should be used in the early period of plant development (in the phase of rosette leaves and booting) in the dose of 5 kg/ha.

“the systematic and consistent application of agrotechnical and chemical control measures, the number of weeds significantly reduced”, according to the Rosselkhoznadzor.
