Over 250 trials on 120 different crops from over 90 countries.


Cherry variety Sandon Rose, Colt rootstock

Cabezuela del Valle, Spain

The application of BOMBARDIER has led to increased productivity of cherry variety Sandon Rose, especially in large calibers of 30 mm and 28 mm. The production of poor-quality cherries as well as their proportion has declined thanks to the application of BOMBARDIER. The average caliber of cherries increased slightly in the variant with BOMBARDIER.
