Effectiveness of selected preservatives in protecting Ugandan grown Eucalyptus grandis wood against termite attack
Termites are one of the major wood destroying agents in the tropics and with the increasing rate of deforestation, there is a need to protect wood from biodegradation in order to extend its service life. In this study the incidence and severity of termite attack on Eucalyptus grandis sapwood treated...
