Effectiveness of hot oil treatment on cultivated 15 year-old acacia hybrid against Coriolus versicolors, Gloeophyllum trabeum and Pycnoporus sanguineus

The effectiveness of the hot oil treatment process on 15 year old cultivated Acacia hybrid was studied. Accelerated laboratory durability studies were conducted on the hot oil treated Acacia hybrid inoculated with fungi Coriolus versicolors, Gloeophyllum trabeum and Pycnoporus sanguineus. The logs...
