The Distribution Maps of Plant Diseases is a printed series which is published by CABI Publishing. For information on diseases mapped from 1974 to present day please see Distribution Maps of Plant Diseases Index. Maps and references give information on the world distribution of important pathogens of agriculture and forestry, and their products. 36 maps are issued annually in 2 sets of 18. Each set comprises both new maps and revisions of previous editions.
Since 1997 the maps have been compiled with assistance from the European and Mediterranean Plant Protection Organization (EPPO).
From 1999 the coverage of the series has been extended to include nematodes in addition to the plant pathogenic fungi, bacteria and viruses.
Presence of a plant pathogen is represented at 2 levels on the world map: at the national level by a spot in the centre and shading of the whole country, and at the subnational level by a cross in the centre and shading of the state/province. Subnational records are provided for large countries and some other countries with detached parts.
The supporting references are provided on the reverse of the map together with a code for the extent or status of the pest. These codes comprise 4 levels of presence and 3 additional categories (not established, eradicated, intercepted only); the latter are not plotted on the map. The extent code for a country or subnational area has been selected by the editors of the maps and is based on all the information available. In addition, more precise location details are often included and comments may be added at the end of the text to explain complications or doubtful reports.
Records are based on bibliographic data from the CAB ABSTRACTS database, specimens in the IMI Herbarium retained at CABI Bioscience, UK Centre [Egham] and plant quarantine information from EPPO's PQR database system. Records are compiled and validated by specialists from CABI Information and CABI Bioscience, and EPPO.
Abstracts to most of the literature references are available from the CAB ABSTRACTS database by subscription to CABPESTCD, PEST CABWeb®, Review of Plant Pathology, Nematological Abstracts or other CABI products. For more information click here.
