A S Harrison & Co is proud to announce our participation in Hort Connections 2025, taking place from 4–6 June at the Brisbane Convention & Exhibition Centre. As the largest horticultural trade show in Australia and New Zealand, this premier event attracts over 4,200 delegates and 200+ leading industry exhibitors.
We’re excited to showcase our innovative biostimulant solutions, designed to enhance flowering, fruit set, crop productivity, and nutrient use efficiency. Visit our agricultural specialists, Andy Koh and Girish Nair, to discover how our plant-based biostimulants can support sustainable growth across the vegetable, fruit, and floral sectors.
Ask about our trial results from HÉLÈS® (Bacillus methylotrophicus). Our 2023 Pukekohe trials highlight its potential as a pre-emergent biostimulant to enhance crop growth and productivity sustainably.
FONGIBACTER® is a wettable powder containing Trichoderma harzianum B97 and Bacillus methylotrophicus B25, enhancing soil microbiota, promoting plant growth, and boosting vegetative vigor through synergistic microbial action.
CÉRÈS® is a microbial biostimulant containing Pseudomonas fluorescens B177 and Trichoderma harzianum B97, enhancing soil structure, root development, and nutrient uptake by restructuring soil microbiota and promoting synergistic plant growth.
AGRADÈS® is a wettable powder containing Trichoderma harzianum B97, enhancing plant growth by amplifying soil fungal flora, breaking down organic matter, restructuring soil, and regulating nutrient release for optimal growth.
COREOS® combines Ascophyllum nodosum and Chlorella vulgaris, offering a rich source of nutrients and phytohormones shown to boost plant growth and reduce pathogen symptoms like Fusarium graminearum.
NUTRILIS® is a wettable powder containing Trichoderma harzianum B97 and Phanerochaete chrysosporium B227, enhancing plant growth by degrading complex organic matter, promoting root development, and amplifying beneficial soil fungal flora for detoxification.

Agricultural additives are essential for effective plant treatment and protection, improving crop yield, quality, and resilience. From adjuvants and chelating agents to emulsifiers and beneficial microbes, each additive plays a key role—enhancing herbicide performance, forming pest barriers, supporting sustainable practices, and extending shelf life through advanced fruit and wood protection.
Soil treatment and protection are crucial in Australian agriculture for long-term productivity and sustainability. Additives like clays improve water retention, while microbial solutions boost soil health. Turf and waste treatments manage green spaces and organic matter. Wetting agents, wollastonite, and xanthan gums support moisture balance, structure, and agri-science innovation.
Water treatment additives play a key role in preserving water quality and ecosystem balance in agriculture. They boost biogas output, reduce emissions, and improve digestion. Custom lagoon treatments remove contaminants, while micronutrients encourage diatom algae growth. These solutions support sustainable water management, regulatory compliance, and efficient, environmentally responsible farming practices.
Enhance crop health and yield with our comprehensive crop protection solutions. From soil and plant treatments to water care, our additives improve nutrient uptake and ecosystem balance. Designed for sustainable farming, our eco-friendly products protect plants, soil, and water—promoting resilience, productivity, and environmental stewardship across your agricultural operations.

Product and customer insights
CHALLENGE A 40-hectare raw water storage dam had persistent issues with blue-green algae (BGA) blooms, leading to taste and odor problems. Despite the presence of an aeration system to address water stratification and mixing, BGA counts remained seasonally high, particularly in summer and autumn. Upgraded aeration in 2018 did not resolve the issue, leaving the […]
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
CHALLENGE A power plant relying on ultrafiltration (UF) and reverse osmosis (RO) faced a critical operational challenge. A wastewater treatment upset severely fouled the UF system, drastically reducing water production. Despite multiple cleaning attempts with sodium hypochlorite and citric acid, transmembrane pressure (TMP) remained high, and flux showed no improvement. The plant’s inability to meet […]
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
CHALLENGE A municipal water reuse plant processing 8 million gallons per day (MGD) experienced severe fouling and scaling issues, including calcium phosphate and silica deposits. With steep feed pressure increases and differential pressures in both stages, the plant required frequent cleanings every 4 to 6 weeks, amounting to 32 cleanings annually. Each cleaning cycle resulted […]
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
CHALLENGE A municipal reverse osmosis (RO) plant on Florida’s west coast, with a 20 MGD capacity, faced high operational costs due to its reliance on 93% sulfuric acid for pH adjustment. The plant used a combination of a brackish water reverse osmosis (BWRO) membranes and fiberglass-wrapped membranes across 10 trains, each operating at 75% recovery. […]
CHALLENGE A gold processing plant in New Zealand sought to improve gold recovery efficiency while addressing high Total Organic Carbon (TOC) levels. Elevated TOC increased the Preg-Robbing Factor (PRF), reducing the plant’s ability to efficiently recover gold during the Carbon-In-Leach (CIL) process. The traditional use of kerosene as a carbon blanking agent offered limited efficacy, […]
CHALLENGE A municipal reverse osmosis (RO) plant, with a capacity of 2 million gallons per day (MGD), faced frequent system cleanings, every 2-4 months, due to rising feed pressure. The plant, which sources water from brackish wells and uses Toray TMG-20D-400 membranes in a (16×7) -> (8×7) train configuration, was operating at 78% recovery. Despite […]
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
