Biology and EcologyTop of page
On contact with the host root, a swelling, the haustorium, is formed, and intrusive cells penetrate through the cortex to the vascular bundle to establish connection with the host xylem and phloem (Dorr and Kollmann, 1995). The parasite develops into a tubercle on the surface of the root, developing to a diameter of 5-20 mm. Secondary roots may develop on the tubercle and make separate contacts with the host root system. After several weeks, the tubercle develops a flowering shoot which emerges above the soil.
Seeds are produced in very large numbers and may remain viable in soil for many years. Lopez-Granados and Garcia-Torres (1999) showed that seed in the field persisted for 6-9 years.
Orobanche spp. depend totally on their hosts for all nutrition, and also draw most of their water from the host root. Effects on the host are generally proportional to the biomass of the parasite, such that the mass of the parasite is reflected in a very similar loss in mass of the host crop (e.g. Manschadi et al., 1996).

Notes on Natural EnemiesTop of page
Many fungi have been isolated from O. crenata. Linke et al. (1992) list those identified in Syria, including Ulocladium species of possible interest for biological control as well as Fusarium and Alternaria spp. In Egypt, 42 fungi were isolated, all non-pathogenic to faba beans (Abdel Kader et al., 1998). Some of these were able to decrease the number of emerged O. crenata and/or to infect them with clear rot symptoms. The most parasitic isolates belonged to Alternaria, Fusarium and Trichoderma.
Means of Movement and DispersalTop of page
Agricultural products of various crops may carry Orobanche seeds if harvested in an infested field.
Agricultural tools should always be cleaned after being used in an infested field to avoid transfer of Orobanche seeds or contaminated soil to non-infested fields.

Detection and InspectionTop of page
After crop establishment, the roots may be carefully retrieved and washed, and inspected for the presence of the typical tubercles, 1-20 mm. Note that the tubercles are easily disconnected from the roots if the root system is pulled out of the soil.

Prevention and ControlTop of page
Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.Phytosanitary Measures
Most countries prohibit entry of major parasitic weed species, including Orobanche spp.
Phytosanitation is aimed at preventing the spread of viable seeds by minimizing the movement of infested soil by farm machinery and vehicles, preventing grazing on infested plant material, treating manure (e.g. composting) and avoiding the use of hay made of Orobanche-infested plants (Jacobsohn, 1984). One should also avoid the use of Orobanche-infested crop seeds.
Hand-weeding of emerged stems is often too late to prevent crop damage but may be worthwhile where infestations are still light, to prevent or reduce future infestations. The stems should immediately be removed from the field to preclude seed shed after pulling.
Because of the strict periodicity of its germination, O. crenata infestation is greatly affected by the time of planting of the crop. Highest infestations occur with early planting of crops in October, November or early December, while those in late December and January are much lower. This date of planting effect has been well documented for Spain, Egypt and Syria (see Parker and Riches, 1993). Unfortunately, late planting almost invariably leads to lower potential yields, but some compromise in planting date may be worthwhile as part of an integrated control programme.
Trap crops may be used to promote germination of Orobanche seeds in soil, without themselves supporting parasitism, in order to deplete the seed reserve. Examples of trap crops for O. crenata include sorghum, barley and Vicia dasycarpa ssp. villosa [V. villosa subsp. varia] (Parker and Riches, 1993). Zemrag and Bajja (2001) showed increased yields of faba bean following crops of fenugreek and coriander. There are few examples of the fully successful use of this principle, but Linke et al. (1991a) recorded a 62% reduction in O. crenata after 3 years of growing V. dasycarpa spp. villosa, and it should be considered in any integrated control approach. Intercropping has also been reported to be effective by Bakheit et al. (2001) using lupin, fenugreek and Egyptian clover (Trifolium alexandrinum).
Soil solarization, based on mulching moist soil with polyethylene sheets for several weeks under solar irradiation, can provide excellent levels of control of Orobanche seeds in the upper soil layers where temperatures are high enough (Jacobsohn et al., 1980), and this has been confirmed in a number of studies involving O. crenata (see Parker and Riches, 1993; Mauromocale et al., 2001). In Syria, yield increases of 330, 440 and 92% were recorded in faba bean, lentil and pea, respectively, following solarization to control O. crenata (Linke et al., 1991b).
Kebreab and Murdoch (1999a) showed that seeds maintained at high mositure and high temperature lose viability relatively rapidly. This could explain the success that has been occasionally reported from prolonged flooding or water. Zahran (1982) reported a 65% reduction in O. crenata infestation of faba bean following a flooded rice crop. A period of at least 6 weeks may be needed.
Tremendous efforts have been devoted to the search for resistant cultivars of faba bean and some less susceptible lines have been developed, mainly based on the Giza 402 line selected in Egypt as early as 1979 (see ICARDA, 1992; Parker and Riches, 1993). One of these lines X123A was the highest yielding variety under heavy infestation in Egypt, but was the lowest yielding in the absence of O. crenata (Ibrahim and Zaitoun, 1999). Progress has been reviewed by Cubero (1991, 1994) and by Alonso (1998) but Petzoldt (1998) concludes that these efforts have so far led only to more or less tolerant small-seeded varieties of V. faba (field or horse bean) and not yet of V. faba var. major [V. faba var. faba], the most important broad bean in the Maghreb region of northern Africa and southern Spain.
Rubiales et al. (1998) screened over 600 lines of pea and related Pisum spp. for resistance to O. crenata in Spain and found 45 with low levels of infestation. Some of these have now been used to develop lines with good levels of resistance for further selection and breeding (Rubiales et al., 2001)
Certain varieties of Vicia sativa show high levels of resistance to O. crenata (Gil et al., 1984).
The fly Phytomyza orobanchia has been used for biological control of Orobanche spp. in the past but there is no evidence that there are currently any deliberate efforts to exploit this organism. Nor are any fungi yet being used as biological control agents.
Glyphosate has narrow selectivity against O. crenata in faba bean (see Parker and Riches, 1993) and has been widely applied at repeated low doses as a post-emergence spray, for example, in Morocco and Egypt. Results have not been altogether reliable, and yield increases are generally modest. The problem of having to repeat application many times through a long season is avoided with the use of the short-season type 'Retaca' which requires only one or two applications of glyphosate before being harvested for green pods (Nadal et al., 2001). More recently, the imidazolinone herbicide imazethapyr has shown greater reliability and usefulness in lentil, chickpea, pea and parsley as well as in faba bean (see Parker and Riches, 1993; Geipert, 1997; Garcia-Torres et al., 1998; Kleifeld et al., 1998; Bayaa et al., 2000). Treatments of imazethapyr in pea, faba bean and lentil have been successfully applied as crop seed dressings as well as sprays (Jurado-Exposito et al., 1996, 1997).
Successful control of O. crenata in faba bean can only be achieved by integration of a range of options. In Syria, Linke (1992) proposed a combination of slightly delayed planting date, with low applications of imazethapyr pre-emergence, or glyphosate or imazaquin post-emergence. A similar combination was suggested in Spain (Garcia-Torres and Lopez-Granados, 1991). Hand-pulling and the use of less susceptible varieties may also be important components. A number of models have been developed which can provide valuable support to the development of integrated control programmes (e.g. Lopez-Granados et al., 1997; Manschadi, 1999).
