Orobanche (broomrape or broom-rape) is a genus of over 200 species of parasitic herbaceous plants in the family Orobanchaceae, mostly native to the temperate Northern Hemisphere.[1] Some species formerly included in this genus are now referred to the genus Conopholis. The broomrape plant is small, from 10–60 cm tall depending on species. It is best recognized by its yellow- to straw-coloured stems completely lacking chlorophyll, bearing yellow, white, or blue snapdragon-like flowers. The flower shoots are scaly, with a dense terminal spike of between ten and twenty flowers in most species, although single in O. uniflora. The leaves are merely triangular scales. The seeds are minute, tan-to-brown, and blacken with age. These plants generally flower from late winter to late spring. When they are not flowering, no part of the plants is visible above the surface of the soil.
As they have no chlorophyll, they are totally dependent on other plants for nutrients. Broomrape seeds remain dormant in the soil, often for many years, until stimulated to germinate by certain compounds produced by living plant roots.[2] Broomrape seedlings put out a root-like growth, which attaches to the roots of nearby hosts. Once attached to a host, the broomrape robs its host of water and nutrients.
Some species are only able to parasitise a single plant species, such as ivy broomrape Orobanche hederae, which is restricted to parasitising ivy; these species are often named after the plant they parasitise. Others can infect several genera, such as the lesser broomrape O. minor, which lives on clover and other related Fabaceae.
Branched broomrape Orobanche ramosa, native to central and southwestern Europe but widely naturalised elsewhere, is considered a major threat to crops in some areas. Plants that it parasitizes are tomato, eggplant, potato, cabbage, coleus, bell pepper, sunflower, celery, and beans. In heavily infested areas, branched broomrape can cause total crop failure.
The stems of Orobanche crenata, a species parasitic on the fava bean, are gathered and eaten in the region of Apulia, in southern Italy, where they are given the name of sporchia.[3]

Etymology
The scientific name comes from Ancient Greek ὄροβος (orobos, “bitter vetch”) + ἄγχω (ankhō, “strangle”).[4] The common English name comes from the English word broom, and the Latin rapum ("tuber").[5]

Control of Branched Broomrape: A Literature Review
Chute spillway of Llyn Brianne dam in Wales A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels . Spillways ensure that the water does not overflow and damage or destroy the dam. Floodgates and fuse plugs may be designed into spillways to regulate water flow and reservoir level. Such a spillway can be used to regulate downstream flows – by releasing water in small amounts before the reservoir is full, operators can prevent sudden large releases that would happen if the dam were overtopped. Other uses of the term "spillway" include bypasses of dams or outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods – when the reservoir cannot hold the excess of water entering the reservoir ove...
