Researchers in Germany discovered a fungal disease called Diaporthe goulteri infecting soybean plants for the first time. This fungus, previously known only from sunflowers in Australia, was isolated from a soybean seed and confirmed through genetic testing. Laboratory experiments showed the fungus can infect soybean stems and cause dark discoloration and tissue damage. This finding is important for soybean farmers as it indicates a new disease threat that may need to be monitored and managed.
