Journal Article 1994

Autor: Berner, D.K. Awad, A.E. Aigbokhan, E.I.

The herbicide imazaquin was tested for efficacy in striga gesnerioides and Alectra vogelii control when applied as a cowpea (Vigna unguiculata) seed treatment. Four sets of experiments were conducted in the laboratory and screenhouse. Two cowpea cultivar, three geographical isolates of S. gesneri...

Journal Article 1998

Autor: Berner, D.K. Williams, O.A.

Cowpea (Vigna unguiculata) is an important source of protein in Africa, but production is hindered by the parasitic plant Striga gesnerioides. Crop rotation with non-host cultivars, selected to stimulate parasite seed germination, is being used successfully to control other Striga spp. and may ha...

Journal Article 1996

Autor: Rugutt, J.K. Fischer, N.H. Nauman, M.A. Schmidt, T.J. Berner, D.K.

The two known cadinanes 2-hydroxy-8α-hydroxycalamenene and 2-hydroxy-8α-angeloyloxycalamenene were isolated from a Louisiana population of Heterotheca subaxillaris. Their 13C NMR spectra were fully assigned by the application of HETCOR, COLOC, COSY, NOESY and DEPT experiments. It was shown on the...

Journal Article 2002

Autor: Ahonsi, M.O. Berner, D.K. Emechebe, A.M. Lagoke, S.T.O.

Striga hermonthica (Del.) Benth. is an obligate root-parasitic flowering plant that severely threatens cereal production in sub-Saharan Africa. A potential biological control option for reduction of crop yield–loss within the season of application is the use of soil-borne antagonists of S. hermon...
