Fast-Acting Algae, Moss, Liverwort & Lichen Control for Controlled Environment Agriculture

BioWorks Hoplite™ – 1 Gallon is a professional-grade, fast-acting contact algicide and moss killer engineered to eliminate stubborn liverwort, moss, algae, and lichens across greenhouses, indoor grow rooms, nurseries, and commercial cultivation facilities. Formulated with 22.11% potassium salts of fatty acids, Hoplite™ delivers rapid, visible results without relying on harsh metal salts, alcohol, or staining chemicals. Whether you are sanitizing propagation benches, greenhouse flooring, hydroponic trays, walkways, or the exterior of growing containers, this concentrated liquid solution restores clean, safe working surfaces while protecting surrounding crops and equipment.

How BioWorks Hoplite™ Works at the Cellular Level

Unlike traditional chemical treatments that leave behind heavy metal residues or bleach odors, BioWorks Hoplite™ utilizes biodegradable fatty acid salts to target non-vascular organisms directly on contact. When sprayed thoroughly onto moist algae, moss, or liverwort growth, the active potassium salts penetrate and disrupt the lipid-protein matrix of the target organism’s cellular membranes. This structural breakdown triggers immediate membrane leakage, rapid desiccation, and complete cell death.

Growers observe clear visual confirmation—characterized by distinct yellowing and browning of treated growth—within 48 to 72 hours of application. In controlled university and field evaluations, Hoplite™ achieved 97.5% moss control just five days post-treatment, outperforming competing contact formulations while maintaining a low environmental footprint.

Key Features & Operational Benefits

Rapid Contact Knockdown: Disrupts cellular membranes on contact for visible yellowing and browning within 48 to 72 hours.
Non-Staining & Residue-Free Finish: Contains zero metal salts and zero alcohol, making it safe for concrete floors, metal benches, greenhouse glazing, poly film, and plastic growing containers without discoloration or corrosion.
Biodegradable Chemistry: Breaks down naturally in the environment, offering a sustainable sanitation tool for indoor agriculture, nurseries, and specialty crop production.
Flexible Harvest & Re-Entry Windows: Carries a 0-day Pre-Harvest Interval (PHI) and a 24-hour Restricted-Entry Interval (REI), allowing seamless integration into active production schedules.
Broad Surface Compatibility: Labeled for use in controlled environment agriculture (CEA), greenhouses, nurseries, structural surfaces, walkways, fences, growing containers, hardened tree bark, and cultivated areas.

Application Rates & Best Practices

BioWorks Hoplite™ is a coverage-driven contact concentrate that requires thorough saturation of target growth for maximum efficacy. Optimal performance occurs when ambient temperatures are between 50°F and 80°F and treated surfaces remain wet long enough for the fatty acid solution to penetrate cellular walls. If moss or liverwort mats are dry prior to spraying, pre-wetting the area with clean water significantly improves uptake and knockdown speed.

Hard Surfaces, Benches & Containers: Mix 8 to 13 fl. oz. of Hoplite™ concentrate per 1 gallon of water (a 1:9 to 1:15 dilution ratio). Apply 8 to 12 gallons of finished spray solution per 1,000 square feet. For thick moss mats exceeding 1 inch in depth, increase spray volume up to 25 gallons per 1,000 square feet.
Cultivated Areas: Dilute 6.8 fl. oz. of concentrate in 1 gallon of water per 1,000 square feet, using up to 50 gallons of solution per 1,000 square feet for dense moss growth. Reapply every 2 weeks or as new growth appears.
Storage & Handling: Store in a tightly sealed container above 32°F away from open flames, as freezing temperatures can damage the formulation.
