General Description of the Research Project This project aims at establishment of effective affordable and versatile management technology for Striga (witchweed), a root parasitic weed that is considered to be the most serious biological constraint to food production in sub-Saharan Africa. Manipulation of the germination process by inducing suicidal germination in the absence of host plants or inhibiting the germination itself, has been a main management target. A strigolactone mimic was synthesized and proved to be effective against Striga. The product is to be further evaluated for efficacy, socio-economic and ecological impact in large areas in farmer’s fields on Striga on sorghum and rice. Further, the efficacy is to be verified on the closely related parasitic broomrapes (Orobanche and Phelipanche spp.) which are of global importance and have recently become problematic in Sudan. Further, work is to address blockers of metabolism of sugars specific to root parasitic weeds to obstruct germination. Several indigenous microbes had been identified as germination inducers or disrupters of Striga germination or as bio-fertilizers. Identified microbes are to be evaluated for efficacy, socio-economic, ecological and environmental impact in farmer’s fields. Further, Striga plants are to be probed for biologically active compounds. Through joint research with Sudanese researchers, Sudan's foundations of natural product chemistry and molecular biology are to be built and human resources are to be fostered. In future the work is to be extended to neighboring countries where Striga is a predominant pest.
