The root parasitic weed, Striga hermonthica, has long been recognized as the greatest biological constraint to food production in sub-Saharan Africa. Development of simple, easy-to-implement, sustainable, durable, and inexpensive solutions is imperative to fully exploit the vast arable areas in the region. To combat S. hermonthica, a project entitled “Improvement of Food Security in Semiarid Regions of Sudan Through Management of Root Parasitic Weeds” was implemented from 2009 to 2015 under the auspices of JICA/JST SATREPS. In the project, suicidal germination approach to reduce S. hermonthica seed bank in soil by inducing germination of the parasite in the absence of host plants through artificial application of germination stimulant was demonstrated, for the first time, as a technically feasible countermeasure. In addition, NERICA5 and Umgar were selected as S. hermonthica-resistant rice varieties under the growth conditions in Sudan. A new SATREPS project on S. hermonthica management in Sudan entitled “Developing Counter Measures Against Striga to Conquer Poverty and Improve Food Security” started in July 2017. The project is to take over successful achievements in the former project and is to introduce an additional activity based on the concept of management through utilization.
