Mekonen, S.Alemu, T.Kassa, B.Forbes, G.[Evaluation of contact fungicide spray regimes for control of late blight (Phytophthora infestans) in southern Ethiopia using potato cultivars with different levels of host resistance.]Evaluation of contact fungicide spray regimes for control of late blight (Phytophthora infestans) in southern Ethiopia using potato cultivars with different levels of host resistance.

The study evaluates the potential impacts of the Drought Tolerant Maize for Africa (DTMA) project run by CIMMYT and the International Institute for Tropical Agriculture (IITA) in 13 countries of eastern, southern and West Africa: Angola, Benin, Ethiopia, Kenya, Malawi, Mali, Mozambique, Nigeria, ...

The common bean, Phaseolus vulgaris, is a vital crop in East and Central Africa serving as a food and cash crop and playing an important nutritional role by providing between 20 and 25% of proteins. Unfortunately bean yields have consistently remained lower than potential yield. One reason being ...

The International Institute of Tropical Agriculture (IITA), the Centro International de Agricultura Tropical (CIAT), and many national agricultural research systems (NARS) have devoted considerable attention to cassava improvement. However, many biotic constraints still limit the expansion of thi...


Herren, H.[Cassava pest and disease management: an overview]Cassava pest and disease management: an overview

Principal component analysis was employed to study the variation patterns in 18 cowpea cultivars developed for resistance to Maruca testulalis Geyer (Lepidoptera: Pyralidae) based on 7 developmental parameters of the pest on floral buds, flowers and sliced pods. On the whole, three developmental ...


Oghiakhe, S.Odulaja, A.[A multivariate analysis of growth and development parameters of the legume pad borer, Maruca testulalis, on variably resistant cowpea cultivars]A multivariate analysis of growth and development parameters of the legume pad borer, Maruca testulalis, on variably resistant cowpea cultivars

Plantain and banana (Musa spp.) are integral components of the farming systems in the humid forest and mid-altitude ecologies of sub-saharan Africa. They provide more than 25% of the carbohydrates for approximately 70 million people in the region. Major constraints to plantain and banana producti...

Two parasitic weeds, Striga gesnerioides (Willd.) Vatke and Alectra vogelii Benth., cause heavy yield losses in cowpea (Vigna unguiculata (L.) Walp.) throughout the semiarid regions of sub-Saharan Africa. Several sources of resistance have been identified, including B 301, a landrace from Botswan...

Considered responsible for one million deaths in Ireland and widespread famine in the European continent during the 1840s, late blight, caused by Phytophthora infestans, remains the most devastating disease of potato (Solanum tuberosum L.) with about 15%–30% annual yield loss in sub‐Saharan Afric...

Colletotrichum gloeosporioides causes anthracnose, the most severe foliar disease of field-grown water yam (Dioscorea alata). The inheritance of resistance to a moderately virulent (FGS) strain of the pathogen was investigated in crosses between tetraploid D. alata genotypes: TDa 95/00328 (resist...
