Shorter-term biological control of wood decay in pre-seasoning pine roundwood as an alternative to chemical methods
M W Schoeman, D J Dickinson
Previous studies on the long-term control of decay in creosoted transmission poles, using Trichoderma and other antagonistic moulds, have met with limited success. However, it is possible biological control is more suited to control of decay on shorter time scales. An earlier study, focusing on pre-seasoning treatment of transmission poles showed that favourable porosity increases could be brought about by an isolate of Trichoderma. Furthermore, it was evident that considerable improvement could be made in developing antagonistic strains of Trichoderma. A study further investigating the use of antagonistic primary mould fungi as biological control agents is outlined.
