This work gives details of some fifty diseases of tropical tree crops which cause very significant yield losses hence compromising or even preventing cultivation. Breeding resistant planting material is currently the most widely used control method. Research is also under way on the rational use of chemical pesticides, the adoption of appropriate crop techniques and on reducing populations of insect vectors of viral and fungal diseases, phytoplasms and Phytomonas.
