Two glasshouse experiments were conducted to assess the influence of three inoculation methods on Scutellonema bradys multiplication on yam (Dioscorea spp.) and on growth and production of the crop. Three separate cultivars of yam were used in the study: two Dioscorea rotundata cultivars (Ala and...

Ce guide de formation presente les problems majeurs, qui font obstacle a l'intensification de l'igname en Afrique. Les plus graves connus, aussi bien au champ que Durant la conservation des tubercules, sont occasionnes par les nematodes (galles, boursouflures), les champignons (syndrome du Betris...

A study of the effect of plant population, fertiliser application, number of suckers retained per stool and desuckering time on the 5th and 6th banana ratoons was conducted on Kibuzi (AAA-EA) plantation from October 2000 to December 2002. The plantation had earlier (October 1999 to October 2000) ...

Rice is the third most important crop in Kenya after maize and wheat. Plant parasitic nematodes (PPN) are a major rice production constraint. The objective of this study was to determine the distribution and abundance of rice PPN in Kenya and their association with environmental variables. Soil a...

Mulching with plant organic matter has been shown to reduce nematode population densities in various cropping systems. The level of nematode control is increased when such mulches are incorporated into the soil as organic amendments. Chromolaena odorata, Tithonia diversifolia and Pueraria phaseol...
