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...

This paper presents a global perspective on bacterial and fungal pathogens that directly infect cowpea foliage, stems, and pods. A brief outline is presented of the main symptoms, distribution, economic importance, epidemiology, and control of bacterial blight/pustule and of 11 fungal diseases: a...

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...

Pearl millet downy mildew (DM) incidence, severity and yield losses of two pearl millet varieties (local and improved) due to the disease were determined in the field. Significant differences in the disease incidence and severity were recorded in the plots sown with metalaxyl-treated seeds and th...

A series of pot and laboratory experiments was carried out to assess the effects of N status of sorghum roots and timing of N application (as NH4NO3) on the germination of Striga hermonthica seeds. Root N concentrations varied from 10 to 26 mg N g−1. The cut root and the root exudates technique u...
