Key Takeaways

  • Tidal Grow AgriScience has received approval to offer its Spectra™ biopesticide in California.
  • The product is designed for use in tree nuts, citrus, and grape crops to boost yield potential.
  • Spectra™ uses chitosan, a natural compound from upcycled crustaceans, as its active ingredient.
  • The biopesticide functions as a fungicide, bactericide, and nematicide while enhancing plant vigor.
  • Approval in California provides growers with new integrated pest management (IPM) options.

Tidal Grow AgriScience Gains Approval in California

Tidal Grow AgriScience, a division of Tidal Vision Products Inc., announced it has begun offering Tidal Grow® Spectra™ in California following approval by the state’s Department of Pesticide Regulation. The multi-functional biopesticide targets pests and diseases while also enhancing plant resilience, with applications across almonds, citrus, walnuts, and grape varieties.


Tidal Grow AgriScience Highlights Chitosan Technology

The active ingredient in Spectra™ is chitosan, a compound derived from chitin sourced from upcycled crab and shrimp. According to the company, its proprietary bioengineering process ensures consistent quality and performance, distinguishing it from other chitosan-based products.

“Chitosan is a powerful active ingredient that is bio-based, yet requires precise bioengineering to deliver specific results, and we’re thrilled the California DPR has approved its use,” said Galynn Beer, VP of Global Sales. “By equipping growers with reliable chitosan-based technologies, we’re helping drive profitability by improving efficacy of existing IPM strategies, all while empowering the growth of sustainable, high-performing agricultural systems.”


Tidal Grow AgriScience Showcases Crop Protection Benefits

Spectra™ activates crops’ natural immune responses, helping plants manage abiotic stressors more effectively. The product also functions as a fungicide, bactericide, and nematicide, offering improved outcomes when integrated with conventional crop protection programs.

Key benefits include:

  • Control of pests and pathogens such as Almond Blossom Blight, Shot Hole, Walnut Mites, and Powdery Mildew.
  • Activation of plants’ natural defenses to reduce vulnerability to stress and disease.
  • Improved nutrient uptake and stronger root development.
  • Synergy with other active ingredients, such as copper, to enhance efficacy.

Expanding Grower Options in Specialty Crops

With California being a major hub for specialty crop production, the approval of Spectra™ marks an important step in broadening growers’ access to sustainable, chitosan-based technologies. Tidal Grow AgriScience positions the product as a tool for improving yield potential, reducing input costs, and supporting long-term crop health.
