Which disease is caused by Fusarium species?

Fusarium wilt is a disease specifically caused by various species of the Fusarium fungus. This disease is characterized by symptoms such as wilting, chlorosis (yellowing of the leaves), and overall decline of the plant. Fusarium has a tendency to infect the vascular tissues, leading to disruption in the plant’s ability to transport water and nutrients, which ultimately results in the characteristic wilting symptoms.

Fusarium species can impact a wide range of plants, including vegetables and ornamentals, and are known for their ability to persist in the soil, making control challenging. Understanding this disease is critical for effective disease management strategies, particularly in crop production where Fusarium wilt can lead to significant losses.

Other options represent different diseases or conditions. Root rot could be caused by various pathogens including other fungi, while yellowing leaf disease may be linked to nutrient deficiencies or other pathologies, but not specifically to Fusarium. Powdery mildew is caused by other fungal pathogens and is distinctly different from diseases caused by Fusarium species. Thus, identifying Fusarium wilt correctly highlights the specific impact of Fusarium on plant health.
