Expert Response
Based on your pictures of the tomato fruit, it could be bacterial speck or bacterial spot.
Bacterial Speck causes small, raised black specks that can become sunken pits as the fruit grows.
Bacterial spot creates sunken black spots.
Warm and humid weather favors both bacterial diseases.
No cure exists for affected fruit.
Remove and destroy any infected fruits to prevent bacteria from spreading.
Wash your hands and tools before handling healthy plants.
Water with drip irrigation or a soaker hose to avoid avoiding overhead watering and splashing water on leaves and fruit.
Space plants to improve air circulation. This helps leaves dry faster, reducing the favorable environment for bacteria.
Prevention involves using disease-resistant varieties and crop rotation.
