Plants cannot eradicate the root cause scientists helpless

The bulbous plant can become a gardener's nightmare because it survived 19 times when the researcher tried to erase it.

According to the Long Room, scientists spent five years in the world's largest field research to test different ways to stop Japanese knotweed but not successful. After 19 failed defeats, the team still did not find a way to control the radial core of the roots.

Root gas plant.

The root gas plant causes trouble for gardeners because it grows unbelievably fast and causes other plants to die. The study sought to eradicate this species of Swansea University at two locations in Taff's Well near Cardiff and Swansea. Scientists tested all 19 plant-killing methods including using chemical mixtures, natural remedies or a combination of both.

The root of the bulb is difficult to control because the underground root grows stronger and faster than the upper tree trunk that the gardener can see. According to the expert team, eradication is impossible and it is necessary to pay attention to the biological characteristics of plants to achieve the best results.

"Basically, we discovered how to best handle invasive plants in real terms. We began to focus on the core of the roots. Currently, most information about gardeners is The effect of this species is based on the story, which leads to profiteering companies that can provide expensive and ineffective treatment solutions, " said Professor Dan Eastwood, team leader. .

According to co-author Dan Jones, co-author of the study, the best chemical to control rootstock is glyphosate . But researchers fear herbicides can threaten wildlife.
