NEMATODES OF BANANAS AND PLANTAINS IN AFRICA: RESEARCH TRENDS AND MANAGEMENT STRATEGIES RELATING TO THE SMALL-SCALE FARMER
Historically, research on nematode pests of Musa spp. in Africa has largely been confined to commercial dessert bananas. Over 85% of published work until ten years ago related to these cash crops and mainly to one nematode, Radopholus similis. In the past decade, nematode research on plantain and highland banana food crops, and other nematodes has steadily increased. There are 17 species of Musa root nematodes in Africa that are recognized to have possible economic importance. Some species are widely distributed in Africa, others are localized; some are indigenous, others are introduced. Of these, most attention has been directed at R. similis, Pratylenchus goodeyi, P. coffeae, Helicotylenchus multicinctus, Hoplolaimus pararobustus, and Meloidogyne spp. The nematode problems in Africa that are still largely, or partly, unanswered mainly come under two headings: firstly, the need for a greater biological understanding of the different nematodes in relation to other constraints, and secondly, identifying control measures that are effective and applicable particularly for the small-scale farmers. The question of how much knowledge gained on commercial bananas is transferable to the problems of nematodes on Musa food crops, especially on their control, has to be addressed. Earlier recommendations for nematological research priorities in Africa have advocated emphasis on non-chemical control strategies (e.g., cultural methods, use of in vitro plantlets, and biological control), and improved information on the relative economic importance and pathogenic variability of different nematodes. The relevance of these to present circumstances and suggestions for additional work on other important aspects, such as banana and plantain cropping systems, is discussed.
