Common crops affected
Why it matters
It makes fruit unmarketable, and a bad early run costs a share of the first harvest; the fix is calcium availability plus steady watering, not a fungicide.
When it appears
Early fruit, after uneven watering, drought, or heat.
How to identify it
- Water-soaked spot at the blossom (bottom) end of young fruit
- Spot enlarging into a sunken dark leathery patch
- Affects fruit, not leaves; first fruits often hit
How to manage it
- Keep soil moisture even; avoid nitrogen spikes.
- Supply available calcium with Calcium Boost.
