Rainy season – a "sensitive" time for pepper pest and disease management
Heavy rain not only raises humidity – favouring pests and diseases – it also means:
- Products wash off easily → much lower effectiveness
- The vine cannot absorb the product in time → wasted costs
- Extra labour, money and time for re-spraying
Without support, 80% of the sprayed product can be "washed away by the rain".
Viet-up 90 – A sticker & penetrant for crop protection products
✅ Key functions:
- Helps products adhere firmly to pepper leaves, even on waxy or smooth leaves
- Improves penetration into leaf tissue – helping the product work effectively
- Reduces losses from rain, wind and heavy irrigation
- Gentle on the crop when used as directed; mixes easily with many crop protection products
How to use Viet-up 90 in the rainy season
| Main crop protection product | Add Viet-up 90 | How to use |

- Use a fine nozzle at moderate pressure for even coverage
