Preventive Treatment
Sporax has been used successfully to prevent establishment and growth of Heterobasidion annosum in cut stumps of conifer tree species that are not already infected. Sporax is a product currently registered by the EPA for this use in Wisconsin.
Sporax is applied salt-shaker style on the surface of a freshly cut stump.

Stumps must be treated as soon as possible after cutting and no later than one day after cutting. Sporax is typically applied from a container with a perforated lid. One pound of Sporax will cover 50 square feet of stump surfaces. This is equivalent to 260, 6-inch (15 cm) diameter stumps or 60, 12-inch (30 cm) diameter stumps.
Sporax is available in 25-pound bags from Wilbur-Ellis Company. As of January, 2006, the cost for a 25-pound bag is $61.25 plus shipping. Shipping cost per bag will be reduced when multiple bags are purchased as one order.
