What is MYKE?

MYCORRHIZAE the unique ingredient
April 17, 2005

When mycorrhizal fungi colonize the plant's root system, they create a network that increases the plant's capacity to absorb more water and nutrients such as phosphorus, copper and zinc. This process in turn enhances growth and favors rapid development of roots and plants.

Mycorrhizae is the active ingredient available in the Growth Supplements MYKE®. Mycorise® logo is the trademark that allows you to differentiate the products containing mycorrhizae. This logo is exclusively used by Premier Tech Biotechnologies.


Mycorrhizal fungi have occurred naturally in the soil for 400 million years. They form a close symbiotic relationship with plant roots. They are called mycorrhizae (from the Greek "mukés", meaning fungus, and "rhiza" meaning roots). However, in most soils that have been disturbed by residential construction, or intensive cropping practices with applications of fertilizers containing pesticides and other chemical products, the mycorrhizae content has considerably diminished, and has become insufficient to significantly enhance plant growth.


There are two major classifications of mycorrhizal fungi: ectomycorrhizal and endomycorrhizal fungi. The prior develop almost exclusively on the exterior of the root tissues, whereas the latter not only colonize the exterior but also penetrate inside the plant tissues where more direct metabolic exchanges can occur with the plant. Ectomycorrhizas are essentially found on trees whereas endomycorrhizas colonize trees as well as bushes and other herbaceous plants.

• Can actually increase the root’s capacity to pick nutrients in the soil
• Unique: no fertilizers, compost or peat mixes contain mycorrhizae
• Increase rapid development of the root system
• Ensure better recovery
• Let plants grow and can tolerate stress such as heat, water deficit
• Increase the survival rate of the plants after transplantation
