Pests & disease (3)
- Coffee berry borer — The 1.5 mm black beetle that drills into a coffee cherry and eats the seed from the inside — the most damaging insect pest of coffee on earth, and the reason a lot can lose points before it ever reaches a cupping table.
- Coffee berry disease — The African fungal rot that blackens green coffee cherries on the branch before the bean inside is finished — the disease that rebuilt Kenya’s farms and sits behind half the resistance ratings in the variety catalogue.
- Coffee leaf rust — The orange fungal disease that strips coffee trees of their leaves — the single most destructive disease in coffee, and the reason half the varieties on modern farms exist at all.
