Blossom end rot
A dark, sunken patch at the bottom of tomato fruits, from uneven watering.

What it looks like

Every field looks a little different. If you are not sure, ask in the app’s Farmers, or ask an agronomist.
When it comes
| Crop | Stage | Check |
|---|---|---|
| Tomato | Fruiting | Scout every 2–3 days |
What to look for
Every 2–3 days, look at every fruit. Small holes near the top of the fruit = caterpillars eating inside (very common in Ghana, treat fast). Sunken wet patches on ripe fruit = a disease. Black sunken patches on the bottom of fruit = the plant is short on calcium or you're watering unevenly.
Also watch for
General advice from crop guides for Ghana. Before you spray, ask your agro-input dealer for a product registered for this pest, read the label, and wear gloves. For a serious attack, call your district agriculture office or an agronomist.
