ProAct is a proven biostimulant for Potatoes with MOIC up to £3,232/Ha

ProAct is a biostimulant product containing 1% Harpin Alpha-Beta (αβ) protein that is made up of 4 targeted peptides.

It is a well proven way of improving potato yield, quality and storability.

When Harpin proteins are applied to the plant the proteins function as elicitors, triggering the plant to activate key defensive and growth responses.

Plants which have been ‘primed’ in this manner then respond faster or stronger to subsequent stress events.

This Complete Biostimulant Offers:

• Nutrient absorption & translocation including increases in the most bio-effective form of calcium in cell walls.
• Tuber (& fruit) firmness
• Photosynthetic activation and abiotic stress tolerance
• A high calcium content in crops is often positively related to increased resistance to bacterial diseases including blackleg.

Key Outcomes of Applying ProAct:

1. Increased yield – (average 8.48% yield increase in 83% of 37 trials, 3 applications. – Plant Health Care trials). Activates the ethylene signalling pathway within the plant increasing photosynthesis and growth¹
   
2. Stimulates Ca2+ translocation, leading to preferential storage in the cell wall improving skin finish^2,3.
