Twenty five sites, representative of seven agro-ecological zones of enset (Ensete ventricosum) crops, were sampled between September 1998 and January 1999. At each site, five 1-2 year old enset plants were sampled to check for the presence of nematodes present in their roots. The predominant nema...

Autor: Speijer, P.R. De Waele, D. International Network for the Improvement of Banana and Plantain

In most regions of the world, nematodes are recognized as important pests of bananas. Because banana nematodes attack the root and/or corm tissues, plant growth and yield are affected. The objective of these technical guidelines is to stimulate interest in nematode resistance and tolerance screen...

A field trial was established at Sendusu. 40 km north of Kampala. Uganda, to evaluate the response of yarn lines, developed by the International Institute of Tropical Agriculture (IITA), to nematode infestation. The field was naturally infested with nematodes and plants were established from tiss...
