Sorghum ergot fungus (Claviceps africana) on ...

The image shows a close-up view of an inflorescence with several flower spikes that have been infected by Sorghum ergot fungus (Claviceps africana). The background is dark and out of focus, indicating that the photographer used a shallow depth of field to emphasize the subject.

The flower spikes are long and slender, each one topped with small white flowers. However, these flowers have been replaced or deformed by pinkish-purplish masses. These masses are the result of fungus growth, which can cause significant damage to the plant's reproductive structures. The presence of this fungus suggests that the inflorescence is no longer viable for producing seeds.

In addition to the infected flower spikes, there are several other features visible in the image. The stem supporting the inflorescence appears green and healthy, but it may be weakened by the fungal infection. There are also some small brownish spots on the surface of the stem, which could indicate further damage from the fungus.

Overall, the image provides a detailed view of the effects of Sorghum ergot fungus (Claviceps africana) on an inflorescence of johnsongrass. The presence of this fungus can have significant consequences for crop yields and plant health, making it important to monitor for signs of infection and take appropriate measures to control its spread.
