Mycormax® Powder | Biological Transplant Starter | JH Biotech Inc.

Size: 1 lb



Mycormax® is a powder form biologically based product containing spores, colonized root fragments, and other propagules of seven beneficial root colonizing fungi species. 

Mycorrhizal fungi live on the roots of plants in a symbiotic relationship. These fungi help plants absorb nutrients and water and physically protect the roots from penetration by disease-causing soil pathogens. Mycormax® rebuilds soil populations of beneficial mycorrhizal fungi after soil fumigation or other events that reduce populations. 

We recommend you apply Mycormax® once a year to maintain the mycorrhizal population. 


  • Physical barrier against root pathogens and nematodes

For direct use to soil, incorporate to a depth of two to six inches. To get a fast start in early spring, concentrate inoculum between one and three inches deep below the seed. In well-worked land, use a Clampco or similar banding equipment.

May also be distributed and disked into soil or incorporated with a mulcher. In rough or unworked ground, best results have been observed with a specially modified land imprinter. For best results apply at minimum rate of 1-5 lb./ac.

MIXING INTO BULK MEDIA May be mixed with most mechanical equipment that allows passage of ¼” or larger particles. Do not crush or grind. Assure that mixing equipment does not heat up in the sun. For use in bulk-mixed container media, use a minimum of 1 lb. per cubic yard. Higher amounts give more rapid root colonization.
