NEW PUBLICATION: Facultative parasitism of Rice Vampireweed

A new paper ‘Host influence on germination and reproduction of the facultative hemi-parasitic weed Rhamphicarpa fistulosa’ was published in Annals of Applied biology in which the germination ecology and parasitism of the facultative parasitic plant, Rhamphicarpa fistulosa (Rice Vampireweed) were investigated in comparison with the obligate parasitic plant Striga hermonthica (Purple Witchweed). We hypothesized that, being a wetland species, germination of

New PARASITE publication on “rice yields under Rhamphicarpa fistulosa-infested field conditions”

This study reports on the existence of resistance and tolerance against Rhamphicarpa fistulosa as well as on yield levels and relative yield losses incurred under R. fistulosa infested field conditions among a range of adapted lowland rice varieties. The facultative parasitic weed Rhamphicarpa fistulosa, is a widespread problem in rain-fed rice production systems in Africa. Little is known about rice
