Jollands P., . (1986) Potential for biological control of root disease of cocoa in Papua New Guinea. [Proceedings Paper]
Abstract
Root disease of cocoa caused by Rigidoporus lignosus and Phellinus noxius became a problem now that large wereas of cocoa were being replanted for the first time and large numbers of stumps were exposed. Artificial inoculation of stumps with spores and mycelial suspension of the two pathogens was unsuccessful though field observations had shown large numbers of stumps to be infected by the pathogens. Stump protection was required and use of a biological agent has the advantage over chemical stump treatment as it degraded the stump and replaced the pathogen in already colonised tissue. Saprophytic fungi isolated from cocoa and Leuceana stumps and fallen logs were tested for their ability to decay wood and to compete with P. noxius in blocks of wood. Two of those tested showed potential and will be further tested in field experiments
