Survival of Poria weirii in Wood Buried in Urea-Amended Forest Soil. E. E. Nelson, Principal Plant Pathologist, U.S. Department of Agriculture, Pacific Northwest Forest and Range Experiment Station, Forestry Sciences Laboratory, Corvallis, Oregon 97331; Phytopathology 65:501-502.

Poria weirii failed to survive in buried wood cubes when urea was mixed with the surrounding soil or broadcast on the soil surface. Survival was closely associated with zone lines formed inside the cubes. If urea similarly can reduce survival of the fungus in colonized roots of stumps and dead trees, it could be an effective control of P. weirii on harvested forest lands.
