The technical guidelines are written in a short, direct, sometimes telegraphic style, in order to keep the volume of the document to a minimum and to facilitate updating. The guidelines are divided into two parts. The first part makes general recommendations on how best to move germplasm of the crop concerned and mentions available intermediate quarentine facilities when relevant. The second part covers the important pests and diseases of quarentine concern. The information given on a particular pest or disease does not pretend to be exhaustive but concentrates on those aspects that are most relevante to quarentine. Where possible, acronyms for viruses are according to Hull et. al (1991).
This handbook contains 13 chapters covering banana (Musa and Ensete) diseases caused by various groups of causal agents and disorders caused by unknown and known factors. Topics discussed include fungal diseases of the foliage, root, corm, pseudostem, fruit (pre- and postharvest), as well as diseases caused by bacteria and phytoplasmas, viruses and nematode pathogens. Information is given on their economic impact, distribution, symptoms, disease cycle and epidemiology, host reaction, and control. Non-infectious disorders, mineral deficiencies, injuries caused by adverse climate and extreme weather, chemical injuries and genetic abnormalities are also described. Topic on quarantine and the safe movement of Musa germplasm is also given. This book, like the last, is for all 'banana doctors' around the world. It is hoped that it serves as a useful field and laboratory guide plus a source of information to all those investigating problems of the banana, abacá and enset crops.
