Nematodes in the roots of coffee trees may affect global coffee bean production.

Scientists have found that two parasites that eat up the roots of coffee trees are affecting the harvest of coffee beans, possibly threatening the global supply of coffee beans.

Scientists have found two parasites in soil samples, both of which are Nematodes, that eat away at the roots of coffee trees, weaken them and reduce harvests, threatening the global supply of coffee beans. Moreover, nematodes do not show obvious symptoms during parasitism and are difficult to detect, but now scientists have developed effective detection methods.

Researchers from the University of University of Leeds in the UK said: "the sad truth is that we have taken samples from different places and found parasites that are destroying coffee trees. "the team's samples were taken from Brazil, Vietnam and Indonesia, and this is the first time scientists have conducted similar studies in these three major coffee bean-producing areas.

In addition to parasitic coffee trees, nematodes are also parasitic on banana trees and black pepper trees that are common near coffee plantations. Scientists hope that this study will help farmers find parasites as soon as possible and take corresponding measures to ensure the harvest.
