Nursery Drench: 

Each pound treats 100,000 seedlings. The 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 ensure 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 the 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 a solution by the end of the day.

Stress Recovery – Small and newly planted trees and shrubs::

Inject along with the original root ball every 1-2 feet and on a grid pattern for established trees.
