How is it used?

Nursery Drench:
  • Each pound treats 100,000 seedlings. Best application method is a 2 step process. Apply 1-2 weeks after sowing just as roots have developed to the sides of cells. Mix with sufficient water to apply as a drench with sprayer. Care should be taken to insure that spores applied are drenched into the media to the level of the roots. Second application 6 weeks before lifting.
  • One week before and after avoid use of phosphate fertilizers. Avoid the use of high phosphorus fertilizer as this treatment would have a negative effect on Ectomycorrhizal colonization. Organic nitrogen fertilizers are recommended.
Established Trees:
  • Mix at the rate of 1/2 lb. to 100 gallons of water. Inject into the ground 6-8 inches on a 2 1/2 to 3 foot grid pattern from the trunk out to the drip line and beyond if possible. Apply 1-2 quarts of solution per injection site. Use up solution by the end of the day.
Stress Recovery
Small and newly planted trees and shrubs::
  • Inject along the original root ball every 1-2 feet and on a grid pattern for established trees.
