Frequently Asked Questions
Q: What kind of product is Tidal Grow® Spectra™?
A: Tidal Grow® Spectra™ is a bioactive fungicide, bactericide, and nematicide - or a biopesticide - that aids in the control of agricultural diseases and pests while boosting plant vigor. It activates the crop’s natural immune system and provides direct control of pathogenic nematodes and microbes through innovative mechanisms.
Q: What is the active ingredient in Tidal Grow® Spectra™?
A: Tidal Grow® Spectra™ utilizes chitosan, a naturally occurring active ingredient that is upcycled from seafood byproducts. Chitosan is a natural compound derived from chitin and is used across multiple industries beyond agriculture. Not all chitosan is created equal, and if not formulated properly, the desired outcome of deterring pests and pathogens can actually promote the opposite. Simply using any chitosan-based product will not produce the same results.
Q: What is chitosan? How is it any different from chitin?
A: Chitosan is a natural compound derived from chitin. Chitin is a structural component in the shells of crustaceans like crabs and shrimp. Chitosan is the deacetylated form of chitin, making it much more soluble and extremely useful in agriculture as a biopesticide and soil enhancer that improves plant health and boosts crop yields when formulated properly.
Q: Where does Tidal Grow source its chitosan? How is it extracted?
A: Tidal Grow Agriscience is the agricultural division of Tidal Vision, the global leader in scalable chitosan solutions. We manufacture precision chitosan formulations using a proprietary zero-waste extraction process, sourcing our seafood materials from the US.
Q: What is the elicitor effect?
A: The elicitor effect is a signaling mechanism whereby substances like chitosan help plants kick their defense systems into gear. Chitosan prompts crops to produce protective compounds and enzymes, boosting their immune response and making them better at fighting off diseases and pests.
Q: Do we need to worry about shellfish allergies since the active ingredient in Tidal Grow® Spectra™ is derived from crab shells?
A: Tidal Grow® Spectra™ is derived from crustaceans and may contain trace amounts of allergens < 1ppm.
Q: What is the REI and PHI for Tidal Grow® Spectra™?
A: The REI (Restricted Entry Interval) and PHI (Pre-Harvest Interval) for Tidal Grow® Spectra™ are both 0 days. EPA has deemed Tidal Grow® Spectra™ exempt from restrictions on re-entry after application or waiting periods before harvest.
Q: How does one product work in so many different ways?
A: Tidal Grow® Spectra™ works in many ways because its active ingredient, chitosan, is multimodal, meaning it activates the plant’s immune system while also directly combating pathogens like bacteria, fungi, and nematodes. For example, it boosts the production of chitinase, which breaks down chitin in pests, making it harder for them to damage your crops. Additionally, by stimulating the immune system, Tidal Grow® Spectra™ enhances nutrient uptake, helping to get more NPK into your crops for better growth.
Q: What's the ideal order of operations for mixing Tidal Grow® Spectra™ with other inputs?
A: To mix Tidal Grow® Spectra™ with other inputs, first reduce the pH of your mix water to around pH 5 and follow the WALES/DALES method: add half the water, then water conditioners, followed by dry products, continuous agitation, liquids, emulsifiable concentrates, and finally surfactants. For specific products like copper fungicides, adjust the pH accordingly to prevent phytotoxicity. If your first jar test fails, try changing up the order of input mixing.
Q: Which products are incompatible with Tidal Grow® Spectra™?
A: Most fungicides, herbicides, insecticides, nematicides, and nutrition products are compatible with Tidal Grow® Spectra™. However, polyphosphate-based fertilizers like 10-34-0 and 11-37-0 should not be mixed with Tidal Grow® Spectra™. Other phosphate fertilizers are acceptable. If you have specific compatibility questions or encounter new incompatibilities, please reach out to our staff for assistance. Regardless, we always recommend conducting a jar test before mixing with our crop inputs.

This episode of Cutting the Curve explores the persistent challenges and emerging solutions in nitrogen management for row crop producers. Host Damian Mason is joined by Trey Cutts and Galynn Beer from Tidal Grow to discuss how traditional practices like fall-applied anhydrous ammonia contribute to nitrogen inefficiency and loss. They introduce alignN, a foliar-applied nitrogen technology designed to improve timing, uptake efficiency, and flexibility. Backed by field trials—including at Mason's own farm—alignN offers a practical tool to align nitrogen delivery with crop demand, reduce overall application rates, and enhance ROI, particularly in a volatile economic environment.
Protect Precious Nitrogen Investments with Tidal Grow® alignN® at the Right Place, Time, Rate, and Source Every grower knows the frustration: you invest in nitrogen, only to watch a big portion of it disappear before the crop can use it. Between run-off, translocation, and missed timing, a significant portion of applied nitrogen gets wasted—and with […]
2026 is teeing up to be a challenging year for grain producers due to declining commodity prices and higher input costs, with growers seeking novel solutions like Tidal Grow’s AlignN fertiliser to save money
Tidal Grow AgriScience, a division of Tidal Vision Products Inc., announces today the launch of its intelligent leaf delivery technology innovation, align Technology, a first-of-its-kind foliar applied nitrogen designed to help growers maximize yields while significantly reducing nitrogen waste. Formulated precisely for broadacre crops, like corn, wheat, cotton, and canola, alignN 18-0-0 delivers encapsulated urea nitrogen directly onto and into the leaf, where it is absorbed for maximum uptake and metabolism.
Trey Cutts, Vice President of Commercial Ag Science at Tidal Grow, shares how intelligent leaf delivery technology is helping growers simplify nitrogen management, boost effectiveness, and align with 4R nutrient stewardship practices for the future.
In this episode of The Intentional Agribusiness Leader Podcast, host Mark Jewell sits down with Dr. Trey Cutts, VP of Commercial Ag Science at Tidal Grow Agroscience. Together, they explore what it truly means to be intentional in agriculture—balancing long-term vision with the day-to-day realities of research, innovation, and leadership. Trey shares candid insights about leading through ambiguity, building team culture, and redefining agriculture’s “North Star” beyond simply producing more.
