An in vitro growth system was used to determine the virulence of two samples of Striga gesnerioides from Zakpota in southern Benin. Cowpea variety B301, previously considered resistant to all races of S. gesnerioides, was susceptible to both samples of the parasite. Two other cowpea varieties, 58...

Striga gesnerioides, a plant parasitic phanerogam, is a known constraint to cowpea production in the sahelian and northern guinea savanna zones of West and Central Africa. A survey was done in 1990 across six countries to collect data on soil types, cowpea phenotype, and cropping systems with rel...
