ProAct helps soft fruit growers protect quality in systems where fruit firmness, consistency and specification are critical. The Harpinαβ technology inside ProAct stimulates increased calcium utilisation in plant cell structures, enhancing fruit tissue strength and resilience.

Harpinαβ contains four active domains of naturally occurring harpin proteins. It mimics bacterial molecules that activate plant response pathways, reinforcing the crop with minimal metabolic cost while supporting calcium-mediated signalling, tissue integrity, firmness and post-harvest quality.
