In substance, this consisted in: - ascertaining the phytosanitaiy problems encountered on smallholdings and the control procedures currently implemented, - studying the appropriateness of those procedures and possibly make modifications, - informing smallholder project supervisors of the advances made in research on the phytosanitaiy protection of rubber trees, and introducing new techniques if necessary, - proposing trials providing answers to specific questions raised by smallholder rubber cultivation in Ghana. GREL supervisory staff mentioned the following phytosanitary problems, in order of importance to them: - revision of Fomes control procedures, possibly setting up trials: effective fungicides, application frequency, duration and period of fungicide applications, need for partial or total isolation of infected trees, current state of research in terms of genetic and biological control, - termite control at the time of planting, - control of leaf diseases in the nursery, - recommendations on rubber-cassava intercropping, - recommendations regarding Loranthaceae .
