Batallón in Industrial Onion variety “Grano de Oro”

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


Industrial Onion variety "Grano de Oro"

Daimiel, Spain

Grano de Oro onions, grown in Daimiel, Ciudad Real, Spain, showed a higher productivity through the application of BATALLÓN 40.6% more or over 34 tons. During the crop cycle, there were difficult weather conditions such as high temperatures and dry air. We had to water the soil more often, resulting in an emergence of root rot fungi. Thanks to the application of BATALLÓN, the onion plants grew stronger. Therefore, they could resist better these adverse conditions and decrease the rots, increasing the amount of tradable onions to 9.3%.
