科学｜コメを脅かす外来植物の実態 / Science | The Reality of Invasive Plants Threatening Rice

Summary

The invasive plant “Oobana Mizukinbai” is having a serious impact on rice crops. Its reproductive capacity is particularly remarkable, and it is spreading across the country since herbicides are ineffective against it. In Mie Prefecture, it has even infiltrated rice fields, and research is being conducted to understand its reproductive mechanisms and effects. This plant was first confirmed to be wild in Hyogo Prefecture in 2007, and its threat has gradually become more evident.

Dialogue

This dialogue is fictional and based on the article.

Chako: Hey Log, this invasive plant is really scary! How does it manage to multiply so much?
Log: Well, the large-flowered waterweed has an incredibly strong reproductive ability. The fact that it can regenerate from even small fragments is a big problem.
Chako: Wow, it can increase that easily?
Navi: Just to add, this plant is also resistant to herbicides, which makes it very difficult to manage. That’s why it’s such a serious threat to agriculture.
Log: Exactly. It must be tough for the farmers.
Chako: Yeah, we need to do something about it soon!

Admin’s Note

Through this article, I was reminded of the serious impact that invasive plants have on agriculture. Particularly, the reproductive ability of the giant buttercup is astonishing, and the fact that herbicides are ineffective against it poses a significant challenge. Imagining the struggles of farmers, I feel that they need some support. I believe it’s important for us to also take an interest in this issue and share information.
