Researchers in China discovered that a fungus called Colletotrichum kahawae is causing a serious disease called anthracnose on buckwheat crops in Yunnan Province. This is the first time this particular fungus has been found on buckwheat, though it’s already known for causing disease on coffee plants worldwide. The scientists characterized how this fungus grows best under certain conditions and tested whether it could infect other important crops like corn, wheat, and potatoes, finding it could potentially harm these crops too.
