Why should I use OmyaPro Sun? 

OmyaPro Sun is an advanced biostimulant that helps crops withstand heat stress and lengthens crop cold temperature phase. It protects plants from sunburn and excessive heat while maintaining photosynthesis, and it extends chill hours to support bud break and fruit set, improving crop yields in regions with mild winters or rising temperatures.

The benefits of OmyaPro Sun for heat stress

  • CE-certified* plant biostimulant which reduces sun damage and heat stress without affecting photosynthesis
  • Easy to apply with standard spray equipment 
  • Rain-fast, long-lasting film protects the crop surface over a long period
  • Protects yield, quality and storability, maximizing profitability for the grower
  • Suitable for organic farming**

Your questions answered

OmyaPro Sun protects annual and perennial crops from sunburn and heat stress that would adversely affect yield and quality. The ultrafine particles of OmyaPro Sun form a protective film on the crop, which reflects excessive sunlight without preventing photosynthetic activity. This long-lasting, rain-resistant film maintains a lower surface temperature on leaves and fruit, reducing water stress.  It allows the plant to continue photosynthesis during the heat of the day, improving the sugar content in the fruit. 

Calcium nutrition is essential for cell wall stability and strength. Calcium deficiency leads to damaged and diseased fruit, including post-harvest damage, reducing marketable yield and quality. OmyaPro Sun provides a pure source of calcium directly to the crop. 

OmyaPro Sun is a wettable powder that can be applied using standard spraying equipment.

For Sun or heat protection, it should be applied before the air temperature rises and can be repeated as required to refresh the film, especially during fast vegetative growth or after heavy rain. Any residual particles can be removed easily from the fruit after harvest.

For extending chill hours, it should ideally be applied after trees have lost their leaves in autumn and throughout the winter and early spring season.

OmyaPro Sun is proven in independent trials to improve marketable yield and quality. Contact us for more information about our trials results.

OmyaPro Sun extends the chill hours for fruit and nut trees, ensuring that plants receive the necessary chilling period to break dormancy properly. This results in more even bud break, better fruit and nut set, and improved yield quality, especially in regions with mild winters or rising global temperatures.
