Nature
Parasitic plants are a major problem in some areas, especially the family of mistletoes (Loranthaceae). Such plants can attack a wide range of hosts; heavy attacks can kill the host plant.
Background
Parasitic plants have been recognized as a significant agricultural threat since the 19th century, when infestations of species like Striga and Orobanche devastated staple crops in Africa and Europe. Their global impact became increasingly apparent with the expansion of monoculture farming, prompting international research collaborations in the late 20th century. Today, the persistent spread and adaptability of parasitic plants underscore their status as a complex, transboundary challenge for food security and ecosystem management.
Incidence
Parasitic plants pose a significant threat to global agriculture and biodiversity, affecting millions of hectares of crops and natural vegetation annually. Notably, species such as Striga (witchweed) and Orobanche (broomrape) infest staple crops like maize, sorghum, and legumes, leading to yield losses estimated at billions of dollars each year, particularly in sub-Saharan Africa and South Asia. Their spread is exacerbated by climate change and intensified farming practices, making control increasingly difficult.
In 2022, a severe outbreak of Striga hermonthica was reported in northern Nigeria, devastating maize and sorghum fields across several states and threatening food security for thousands of smallholder farmers.
