Chilli Flower and Fruit Drop: Root Causes & Fruit Set Solutions
Why are chilli flowers dropping? Learn temperature stress, moisture fluctuation, boron and calcium deficiency, and hormonal drop solutions.
Visible Symptoms
Abscission and premature dropping of flower buds and newly set pin-head fruits, leaving bare flower stalks and drastically reduced fruit yield.
Primary Causes
- Extreme temperature fluctuations (day temp > 35°C or night temp < 15°C causing pollen sterility).
- Moisture stress: alternate severe drying followed by heavy flood irrigation.
- Micronutrient deficiency: specifically Boron (poor pollen tube germination) and Calcium (weak abscission layer).
- Severe thrips feeding inside the open flower corolla damaging anthers.

Frequently Asked Questions
Does heavy chemical spray during flowering increase flower drop?
Yes. Spraying harsh chemical insecticides with high surfactant concentration during midday heat damages delicate stigmas and dries out pollen grains, triggering massive flower drop.
