New paper: Can Striga and Rhamphicarpa co-occur in rain-fed rice?

Stella Kabiri's first paper has been published in Weed Research. The paper describes how Striga asiatica and Rhamphicarpa fistulosa are parasitic weeds of rain-fed rice that are partly distributed in similar regions in sub-Saharan Africa (SSA).  Particularly in Tanzania, these two parasites are present in farmers’ fields in the same rice growing landscape. The paper demonstrates a non-overlapping ecological range between the habitats of these two weeds that is dependent

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. Two resistance classes (pre- and post-attachment) and several resistant genotypes have been identified among NERICA (New Rice for Africa) cultivars under laboratory conditions (in vitro) previously. However, little
