Agrimm Technologies Ltd



Agrimm Technologies was founded in 1984 by medical scientists David Gale and John Hunt, specialists in Immunology and the study of the human immune response. Their vision was to advance sustainable farming in New Zealand by applying innovations from medical research to create technologies for Agricultural Immunisation (Agr-Imm). Pioneering studies on the natural saprophytic fungus family Trichoderma revealed its beneficial bioactivity on plants, leading to the development and registration of a range of products incorporating multiple Trichoderma strains. These products have been proven to enhance crop health, disease resistance of plants, and overall quality and yield performance.

Early adopters reported positive crop results, leading to the growing popularity of this eco-friendly approach among progressive growers who prioritize quality, profitability and environmental benefits.

The Early Days

In its early days, Agrimm operated from various spaces in central Christchurch, adapted to serve as laboratories, offices, and manufacturing facilities. However, the company had long sought a unified location to integrate and house all its operations. In 2005 a rural block on the outskirts of Lincoln was purchased and purpose-built facilities at this current location still operate proficiently, offer a rural and private environment, while being conveniently close to the scientific hub of Lincoln.

Our First Product

Agrimm’s first product, the TrichoDowel, was registered in 1987 for the control of Silverleaf in Apple trees. After extensive Australasian field trials, use in grapevines for trunk disease was approved in the late 1990s. The dowel was also used alongside a liquid injection registered for the treatment of Armillaria in kiwifruit vines. During the same period, a pruning wound dressing called TrichoSeal was developed and marketed, all utilizing the same Trichoderma bio-active. To improve recognition and market positioning of these woody plant/vine applied products, Agrimm launched the Vinevax range in 2004.

Primary Focus

The company’s primary focus remained Trichoderma research and development and after multiple collaborations with Lincoln University research new Trichoderma strains were exclusively licensed. The company successfully registered and marketed products, Tenet for Onion white rot control (soil applied granule) and Sentinel a grapevine foliar applied botryticide (WP – wettable powder). In-house research led to the additional registration of Unite for root disease control, applied as a soil drench. These successes underlined the company’s strategic commitment to R&D and showcased the efficacy of well-researched and tested Trichoderma strains in different applications.

John Hunt

Tragically, in 2007, Agrimm faced the untimely loss of one of its founders, John Hunt, who passed away after a short illness. His enthusiasm, technological expertise, and dedication to working closely with growers left a lasting impact on the company.


In 2015, Agrimm took back direct control of its product sales and distribution by leveraging its reseller network. Concurrently, Agrimm established a fresh licensing agreement with Lincoln University to commercialise research that demonstrated the effectiveness of a three-strain combination of Trichoderma in reducing Psa (Pseudomonas syringae pv. actinidiae) symptoms in kiwifruit vines. This new product, branded Kiwivax, obtained provisional registration and was successfully marketed to the kiwifruit industry.

Our Commitment

Agrimm remains committed to conducting research that brings commercial value to growers and farmers. The company is currently a partner in the Lighter Touch program, participating across diverse sectors like arable crops and strawberries.

Over the past 30 years, Agrimm has demonstrated its ability to improve crop health across a variety of sectors and looking ahead to the next 30 years an even broader adoption of their methods into both conventional and integrated crop management approaches.
