Researchers found that three different fungal species, not just one, cause a disease called Phomopsis cane and leaf spot in grapevines grown in Southern Europe. While Diaporthe ampelina remains the primary culprit, two other species (D. eres and D. foeniculina) can also cause the same disease symptoms. Interestingly, these different fungi prefer different temperatures for growth, which means farmers may need to adjust their disease management strategies based on which species is present in their vineyards.
