  • Orobanche infections reduce biomass of hosts at the first stages of infection on both contrasting faba bean cultivars.
  • It is likely that plant growth-defense tradeoffs have a direct negative impact in host resource allocation.
  • Source-sink relationships explained the dry weight diversion from legumes to O. crenata during the last phases of infection.
  • O. crenata increase host root dry mater, maintain host vegetative parts; and delay and reduce host reproduction.
