New paper: NERICA rice cultivars and their resistance to Striga

Please find attached a new paper on parasitic weeds published in Field Crops Research. The online link is: http://authors.elsevier.com/sd/article/S0378429014002883 Summary The parasitic weeds Striga asiatica and Striga hermonthica cause high yield losses in rain-fed upland rice in Africa.

Blog on Parasitic Weeds: “Unknown rice parasite threatens harvests in Africa”

Few agronomists are familiar with Rhamphicarpa fistulosa, a fragile weed with white flowers, from the broomrape family. Yet this root parasite is increasingly affecting rice cultivation in Africa. This has become clear from the initial results of the research programme PARASITE on parasitic weeds in rice in sub-Saharan Africa. The rice pest was described by the Beninese agronomist Gualbert Gbèhounou

MSc-research Djoeke Langeloo

I am studying the reproductive success of Striga asiatica and Rhamphicarpa fistulosa related to different sowing dates and crop cycle length. So I am looking if the number of capsules and the number of seeds produced by the weeds will change with a different sowing date of the rice (sown between half December 2011 and half February 2012) and/or with different crop
