Hogweed was brought to Russia many decades ago from the North Caucasus as a forage crop for cows, recalls the Director of the research Institute of protection of plants Vladimir Alekhine. However, since it has a bitter taste, cows are not too bestowed. In addition, it was found that the Hogweed to feed the cows at all dangerous. But it was not even that. Hogweed can spread with great speed and take all the new area, completely destroying the entire ecosystem. Where it grows this species, is no longer growing anything. Specialists calculate that 1 square meter Hogweed is able to distribute 20 thousand seeds that can go to 5-6 meters. In the soil it will be another 30 kidneys, and each may germinate on the plant. For this reason, the mowing or burning Hogweed is a useless measure. When Russia realized what the “snake” have warmed, it was too late: Hogweed took the first unused land, then got to the suburban areas and to the arable land. Now fully lime it is impossible, says Vladimir Alekhine – it’s too much space he took up.
But there are measures that probably will work for some period of time in a single area, say, of a holiday village. And the first of them is the herbicides on the basis of glyphosate (active ingredient), the most famous of which is roundup. To work they need the seedlings from: herbicide enters the leaf, penetrates the root system and the plant fully dies, says the Alekhine.
the initiators of the project borshevik.tilda.ws advised to use a herbicide with a content of active ingredient 360 g/l Need to be added to 1 liter of water, 24 ml of herbicide and moisten with a solution of 70-80% of the leaf surface with a spray gun or a paint brush. Handle them several times per season. In this case, if outside the cultivated area grows the cow parsnip, it will have to mow before seeds did not reach cleared land. Mowing should necessarily protecting the skin from possible contact with cow parsnip.
Also, this species likes light. And if you cover the area with black tape, and the top to plant any plants, it will have an effect. But this is not to forget to mow the area outside the cleared area. Will work well as plowing and repeated disking (tillage, top soil) followed by sowing of a replacement culture. But, according to some scientists, to effectively replace the Hogweed, you need to understand which plants will be able to resist him. And this requires research.
However, experts are sure to win Hogweed irrevocably only by uniting “the world.” But it requires more effort, time and money. According to some estimates, to fully bring bursevito the territory of Russia will require a minimum of five years and about 1.3 trillion rubles. Now in several regions of the work programme of combating Hogweed. For example, in the Moscow region citizens whose plots are overgrown with Hogweed, can fine for the sum from 2 to 5 thousand rubles, officials – 20-50 thousand. This experience is proposed to extend to other regions. However, you need to understand that the main land owner in the country is the state on its balance sheet is about 92 per cent of the land.
