Figure 1. The fungus that causes gray mold often sporulates on infected tomato stems.
Figure 2. Gray mold on infected tomato stem.
Figure 3. Gray mold lesions on leaves are often light brown or gray, often on the edge of the leaf and may show a ring-structure. Note sporulation of fungus observed in the crack of the lesion.
Figure 4. Gray mold of tomato fruit. Note sporulation of fungus.
Figure 5. Gray mold lesion on tomato leaf.
Figure 6. Gray mold on tomato fruit.
Figure 7. Gray mold on tomato leaf petiole.
Figure 8. Gray mold on leaf lesion on margin of tomato leaf. Note sporulation.
Figure 9. Tomato flower blossom with gray mold sporulation appears to have fallen on leaf where a new lesion has started.
Figure 10. Conidia of the gray mold fungus fall onto tomato fruit where they may induce the reaction shown here resulting in a ‘ghost lesion’. While the lesions will not expand further, the appearance may reduce marketability.
