If the host contact and penetration is not
established within few days, the parasitic seedling dies. Hence,
measures targeting parasitic germination or radicle growth
might efficiently control infection. It has also been shown that
intercrops with cereals can reduce Orobanche crenata parasitism
on legumes, allelopathy being a major component for the
reduction.12 It is thus suggested that cereal roots might be
exuding substances that reduce O. crenata development, thus
preventing parasitism. These allelochemicals might have a
direct application for broomrape control that should be
explored.
