Mycorrhizae, ancient fungi that have been aiding plant survival for around 450 million years, are often overlooked in modern agriculture, particularly in soilless cultivation. These fungi play a crucial role in helping plant roots absorb nutrients, but many modern agricultural practices strip the soil of this essential microbiome, leaving roots to work harder to obtain the necessary nutrients.
The Importance of Viable Mycorrhizal Products
Not all mycorrhizal products are created equal. Some contain viable spores that can colonize roots and help plants cope with environmental stress, while others do not. Ineffective products can be a costly waste, as they do not provide the intended benefits. Premier Tech, a leading company in this field, has developed a reliable production process to ensure the viability of their mycorrhizal spores.
Martin Trépanier, Scientific Expert Director of Active Ingredients at Premier Tech, explains, “We built the world’s largest endomycorrhizal inoculum production facility in 2000 and industrialized the process. Our spores are designed to effectively colonize roots.” Unlike some other methods that rely on greenhouse-grown mycorrhizae, which may not survive the production process, Premier Tech’s sterile and highly controlled environment ensures consistent quality.
The Choice of Rhizophagus Irregularis
Premier Tech conducted extensive trials to select the most effective mycorrhizal species. After thorough testing, they chose Rhizophagus irregularis (formerly known as Glomus intraradices) for its ability to perform well across a wide range of growing conditions. Geneviève Lachance, Project Manager of Active Ingredients at Premier Tech, notes, “We prefer one species that works almost everywhere over a mix of species that only perform in specific conditions.”
Field trials have demonstrated that Rhizophagus irregularis is particularly effective at helping plants absorb nutrients, especially phosphorus, and it shares these nutrients with the plant rather than hoarding them. Félix LaRoche-Johnston, Innovation, Research & Development Manager at Premier Tech, adds, “It adapts to a wide range of pH levels, and its efficient nutrient transfer behavior sets it apart.”
Premier Tech’s AGTIV® REACH™ Line
Premier Tech’s AGTIV® REACH™ line is designed around Rhizophagus irregularis, with the goal of improving root health and overall plant performance. Whether used as an inoculant or blended into their PRO-MIX® media, this product helps plants absorb more water and nutrients, better handle stress, and thrive with less intensive management.
Martin Trépanier concludes, “AGTIV® REACH™ also contributes to soil structure and nutrient cycling, including key nutrients like phosphorus, zinc, manganese, and copper. It ensures that crops not only survive but thrive without constant intervention.”
