Costello produces high treated yields in all locations, rotations and on all soil types. Like JB Diego, Costello performs well in all weather conditions, an important asset on UK farms in recent years.

Costello has outstanding grain quality, with once again the highest specific weight on the AHDB RL and a HFN higher than any Group 4 and most milling wheats. It also has a high protein content.

Superb, reliable grain quality provides growers with security at harvest and widens market opportunities.

Disease resistance


Costello has excellent all-round disease resistance, particularly to yellow rust, Septoria tritici and Fusarium. Costello reduces the risk for growers in high disease seasons and could help to manage costs, which is particularly important in the second wheat situation.
