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 to act
Prevent with steady moisture and calcium availability through fruit sizing.
What to look for
- Sunken, leathery lesion at the blossom end
- Worst during heat and irrigation swings
- Early and rapidly sizing fruit affected
- No foliar disease signs
How to manage it
- Keep soil moisture even; avoid nitrogen spikes.
- Supply available calcium with Calcium Boost.
