Item Plant-parasitic nematodes-important pathogens in tropical agriculture(1956) Whitehead, A.G; East African Agriculture and Forestry Research Organisation, KenyaThe object of this article is to draw attention to the threat of plant-parasitic nematodes, or "eelworms", to tropical agriculture. It is neither possible nor desirable to give here a detailed account of the numerous species known to cause damage to tropical crops; but the author plans to publish such a review elsewhere. It is hoped that this article will stimulate interest and lead to a wider knowledge of the diseases of East African crop plants in which eel worms playa part.Item Root-Knot Nematode Surveys of Cultivated Areas in East Africa(1960) Whitehead, A.GSeveral species of the plant-parasitic nematode genus Meloidogyne Goeldi ("root-knot" nematodes) are known to be widely distributed in East Africa, i.e. in Kenya, Uganda, Tanganyika and Zanzibar (Whitehead. Unpublished data). Their presence in the roots of infested plants is generally associated with the production of "knots" or galls in the roots. Within which the nematodes feed. Such galls. Not to be confused with the bacterial nodules of legumes, or other gall-forming organisms, are known on the roots of almost every major and minor crop plant and on a large number of weed species in this region.
