Mode of action

Alpha Naphthyl Acetic Acid (ANAA) acts as a synthetic auxin and mimics the natural plant hormone indole-3-acetic acid (IAA). Its mode of action involves promoting cell division and elongation in plants, leading to enhanced root growth, improved nutrient uptake, and overall plant growth stimulation. ANAA helps in fruit setting and enlargement and can enhance seedling vigour. By regulating plant growth processes, ANAA contributes to healthier and more vigorous plants.
