Cowpea [Vigna unguiculata (L.) Walp] is a major food legume the semi-arid region of Sub-Saharan Africa. Recently, two parasitic weeds, Striga [Striga gesnerioides (Willd.) Vatke] and alectra [Alectra vogelii Benth.] have become a major threat to cowpea cultivation in this region. A landrace of co...

Independent inheritance of Striga and Alectra resistance in cowpea genotype B301
The parasitic weed, Striga gesnerioides (Willd.) Vatke, is a major constraint in cowpea [Vigna unguiculata (L.) Walp.] production semi-arid regions of sub-Sahara Africa. Several sources of resistance have been identified. Of these, B301 has shown complete resistance to Striga across several count...

Evaluation of seed treatment chemicals for the control of seedling bacterial blight of cowpea in Northern Nigeria
The parasitic weeds Striga gesnerioides (Willd.) Vatke and Alectra vogelli (Benth.) cause considerable demage to cowpea [ Vigna unguiculata (L.) Walp] in the semiarid regions of Africa. Systematic screening has revealed few cowpea varieties to be resistant. Of these, B 301 is resistant to both st...

IT 84S-2140 and IT 85F-1517 (cowpea varieties) susceptible to scab disease caused by Sphaceloma sp. were treated with severely infected cowpea plants in 1989 and 1990 field trials. Different levels of disease intensity were generated by treatment with benomyl using two different methods of applic...
