Thiourea 99% for dragon fruit – Off-season treatment for even flowering
Off-season treatment – a key technique for dragon fruit growers
Dragon fruit is a high-value fruit crop, especially when treated to:
✅ Flower out of season (off-season)
✅ Harvest when supply is short and prices are higher
✅ Improve yield and fruit quality
Traditional methods (withholding water, creating artificial drought) are often less effective or labour-intensive.
Thiourea 99% is a modern option for faster, more even treatment.
Effects of Thiourea 99% on dragon fruit
- Breaks dormancy: stimulates the plant out of rest and pushes flower buds
- Stimulates flower-bud differentiation: even flowering, strong flowers, better fruit set
- Useful in the off-season: helps growers plan output and timing
