Incorporating an herbicide resistance gene into tropical maize with inherent polygenic resistance to control Striga hermonthica (Del.) Benth por Menkir, A., Chikoye, David, Lum, F.

“…Striga hermonthica is a widespread parasitic weed species that can causeconsiderable yield loss in susceptible maize cultivars in West and CentralAfrica. To use low doses of imidazolinone herbicides for controlling thisparasite, maize cultivars should possess resistance to this group ofherbicides as they kill both maize and S. hermonthica. …”
