How a Pueraria Plant Wins the USA

Pueraria like no other plant personifies the triumph of chaos. A relative of peas, this vine was imported to the USA from Japan in 1876 to combat soil erosion. But pueraria was not satisfied with this alone: ​​unpretentious and fast-growing (up to 30 centimeters per day), it covers trees, lampposts and even buildings with a dense carpet. Under this carpet disappeared hundreds of thousands of hectares in 20 states.

However, the damage from pueraria may be even greater. Scientists from Clemson University in South Carolina claim that this plant releases carbon from the soil of its ecosystems (pictured is a forest in Mississippi). “Continuing for decades, this process can accelerate climate change,” says ecologist Nishanth Farayil.

Is it possible to stop the vine? While the creators of herbicides are puzzling, gardeners can always take advantage of the old proven method - dig up weed roots.

East-Asian lazarusnaya lianoobraznuyu plant kudzu or pueraria lobed (Latin.Pueraria lobata) is an invasive plant, which in the USA is called “plant cancer” or “green plague”. Invasive, from the point of view of nature conservation, are called alien plant varieties, which have a negative impact on the local flora and fauna and on humans by harmful substances contained in them and displace other species.

Already in spring, it grows very quickly, so that it shields sprouts of slowly growing native plants from the light. In the south east of the United States of America, it has already destroyed large spaces. Now it has found its way to Canada.
The South Asian loach was discovered in July on a southern slope overlooking Lake Erie, near Leamington, Ontario, on a farm, 35 miles southeast of Detroit, Michigan.

Although the area that flooded the plant was about 110 meters long and 30 meters wide, OIPC, the competent committee for invasive plants in Ontario, reported the urgent need to "take urgent measures to prevent the spread of the ivy-like plant in Ontario."

With a growth rate of 30 cm per day, the plant belonging to legumes covers everything in its path: fences, trees, grain fields, and even buildings.A thick leafy plant climbs onto electric towers and power lines that break under its weight. Trees either collapse under its weight or die from a lack of light.

“Kudzu can completely capture the landscape, which becomes a kind of desert. It destroys the diversity of species, ”said Rowan Sage, professor of ecology at the University of Toronto, who has been researching this plant for 20 years. - “It has a strong growth. It produces sprouts that winds around itself and is supported by it. So the plant covers other vegetations and removes them from the ecosystem. ”

Originally from East Asia, kudzu was brought to Philadelphia in 1876 for an exhibition on the day of the United States centenary, as an ornamental plant, from Japan. Later it was used to control erosion and as a fodder plant.

As a result, it flooded large areas in the south of the United States, and, despite all efforts to detain him, spread to the north. An attempt to contain the so-called “creeping plant that eats the south” costs the American farmers, according to reports in the press, annually $ 500 million.

Sage says the plant has spread to many places in North America, as well as to the deforested region of the Amazon lowlands in Brazil. It is not known when the plant first took root in Canada.

The liana plant is usually spread by the root system, but also grows seeds (legumes). From one root grow to 30 shoots.
“If you ever get kudzu root, the plant will grow unless it is very cold in winter or lack of water,” says Sage and adds that kudzu root fibers die at minus 20 degrees Celsius.

By effective methods of suppressing wild growth of a plant it is cutting, mowing, controlled fires and herbicides. According to the IOPC, the use of grazing animals like goats and pigs was also successful.

“If you find it, you need to neutralize it immediately,” advises Sage. “As soon as it has been strengthened, it is necessary to resort to radical measures. It is easy to pull out, but it multiplies and regenerates. Therefore, getting rid of it can be expensive. ” Highly valued in its homeland as a medicinal and forage plant growing in the open sun, it can be a carrier of a rusty soybean fungus that reduces the yield of soybeans.Soybeans are the main crop grown in the south of Ontario.

There are other invasive plants, such as Japanese bamboo and the yarrow (Myriophyllum spicatum) that penetrated from Asia to Canada. Also, invasive plants were brought from Europe over time. For example, loosestrikes, ornamental garden plants. It captured the wet areas of North America. The native plants growing there must make room.
The location of the vine plant in Ontario is monitored and explored, says Sage, and will be removed in the fall with the money of the federal government and the government of Ontario.
