STIM XL – Natural Strength When Crops Need It Most

Modern agriculture faces increasing environmental pressure, from unpredictable weather to nutrient stress. STIM XL is a powerful biostimulant solution designed to help crops withstand these challenges, delivering natural resilience, recovery, and consistent growth.

Produced from 100% pure Ascophyllum nodosum, STIM XL harnesses the benefits of cold-pressed seaweed technology to support crops at critical growth stages without the use of heat or harsh chemicals.


Nature’s Original Stress Management Tool

Among all seaweeds, Ascophyllum nodosum is the most researched species for enhancing plant tolerance to abiotic and biotic stress. STIM XL captures these natural benefits using a Soft & Smart cold-extraction method that preserves the full spectrum of bioactive compounds in their original, most effective form.


Designed to Protect, Support, and Recover

Environmental stress reduces crop efficiency long before visual symptoms appear. STIM XL works proactively by providing a comprehensive natural support package:

  • Polysaccharides: Essential for cell integrity and energy storage; maintains function during cold, heat, or drought.
  • Essential Amino Acids: Promotes protein synthesis and helps plants conserve energy during recovery and yield formation.
  • Bio-Available Nutrients: Micronutrients that act as catalysts for enzymatic activity and metabolic efficiency.

Cold-Pressed Quality for Immediate Use

Because STIM XL retains its natural active ingredients in their original form, it ensures maximum bioavailability and rapid physiological responses. Unlike heavily processed products, it supports the plant’s natural processes to optimize hormone balance and root-shoot signalling without forcing unnatural growth.


A Perfect Fit for Integrated Nutrient Management (INM)

STIM XL is designed to enhance existing nutrition and protection programs. It is an ideal tool for use during early establishment, ahead of forecast stress events, or during critical reproductive phases like flowering and grain fill.
