ProAct, p., harpin αβ protein – 1.0% fertilizer

Next-Generation Plant Physiology Management

ProAct is not merely a fertilizer but a cutting-edge biostimulant developed by the US-based company Plant Health Care. At its core is the harpin αβ protein (1.0%), a natural protein that mimics a pathogen attack, thereby triggering the plant's endogenous defense mechanism known as 'Systemic Acquired Resistance' (SAR). This biological signal primes the plant to perform better under stress conditions.

Why ProAct is a market-leading solution

The product works at the cellular level, shifting plant energy from simple vegetative growth to the fortification of physiological barriers. Rather than providing bulk nutrients, it trains the plant to proactively manage environmental challenges.

• Environmental Resilience: Crops treated with ProAct exhibit higher tolerance to heat, cold, and drought stress.
• Marketable Quality: By strengthening cell membranes, the product significantly improves the storage life and durability of fruits, vegetables, and specialty crops.
• Application Efficiency: Designed for foliar application, the powder form ensures rapid uptake and physiological response during the growing season.

Plant Health Care is globally recognized for its expertise in biological solutions, and ProAct serves as a testament to their focus on quality and safety. It is widely used in high-value horticulture, including fruit orchards, vineyards, and vegetable crops, as well as in corn production to secure yields against unpredictable weather. Classified under hazard class 4, it is a safe and reliable tool for modern agronomy, aligning perfectly with sustainable and integrated crop management systems.
