65, 581587. Evol. J. The points of vulnerability of some underground events, key for their parasitism such as crop-induced germination or haustorial development are reviewed as inhibition targets of the broomrape-crop association. Technol. 31, 2730. The major strategy that specifically impedes the broomrape capacity to penetrate the host once the radicle has made contact with host root, is based on the use of host resistance, either genetic resistance obtained by breeding (Prez-de-Luque et al., 2009; Yoder and Scholes, 2010), or induced resistance by abiotic or biotic agents (Gonsior et al., 2004; Kusumoto et al., 2007). In addition, inhibitors of ABA catabolism inhibit the germination-triggering effect of host-derived strigolactones. Phylogeny of the parasitic plant family Orobanchaceae inferred from phytochrome A. They are exuded by the crop to the rhizosphere under nutrient deficient conditions in order to promote symbiotic interactions (Akiyama et al., 2005). Besides arginine and aspartate, other major forms of amino acids translocate from the host phloem but they are rapidly utilized by broomrape. Biological traits in broomrape such as achlorophyllous nature, underground parasitism, the physical connection and growth synchronization with the crop, and the exclusive uptake of resources via crop vascular system rather than from the soil make broomrape control a challenging agricultural task. Striga hermonthica MAX2 restores branching but not the very low fluence response in the Arabidopsis thaliana MAX2 mutant. Z., Huang, K., Wickett, N. J., Alford, S., et al. On the contrary, weedy broomrape species are usually generalists attacking annual crops (Schneeweiss, 2007). A new class of conjugated strigolactone analogues with fluorescent properties: synthesis and biological activity. Ecological of weed seed size and persistence in the soil under different tilling systems: implications for weed management. Weed Sci. Certain amino acids strongly inhibit the early development of broomrape without phytotoxic effects in the host (Vurro et al., 2006). Sci. 2022 Mar 23;13:733116. doi: 10.3389/fpls.2022.733116. Natural pesticides derived of microbial and plant origin are considered to be less harmful because they usually biodegrade quicker, resulting in less pollution-related problems. Broomrapes are sap-sucking 'plant pilferers' that steal their food from the roots of other . Is seed conditioning essential for Orobanche germination? doi: 10.1002/9780470168011.ch4, Joel, D. M., Kleifeld, Y., Losner-Goshen, D., Herzlinger, G., and Gressel, J. When they are applied in vitro to seeds of P. ramosa and O. minor, they bypass the effect of germination-inducing factors, promoting broomrape germination in absence of host or any germination stimulant (Cala et al., 2015). In those cases, broomrape displays a pathogenic nature promoting disease in the crop mainly through negative effects on the crop photosynthetic machinery and hormonal balance (Stewart and Press, 1990; Mauromicale et al., 2008). It cost around $6,000 an acre.. Res. 62, 1048510492. 18 Sep 2020. A., and Garca-Garrido, J. M. (2009c). This lead us to build the list of the major feasible components that a model designed to quantify the effects of cropping systems on pest dynamics should include for specific broomrape control. 42, 5760. doi: 10.1093/jxb/34.5.610. However, instability of this compound, particularly at pH > 7.5, and lack of optimal formulations rendered this technique not applicable (Saghir, 1986; Babiker et al., 1987, 1988). The Broomrape takes its food, nutrients, and water from the roots of the Bursage which weakens the Bursage. Res. 51, 44874503. Broomrape management elsewhere Israeli cooperators have been working on broomrape management for several decades Eizenberg, Goldwasser, and others Weed is not eradicated, but is managed to an acceptable level Management is based on carefully -timed and -placed herbicides to disrupt key broomrape life stages Weed Sci. Quinone oxidoreductase message levels are differentially regulated in parasitic and non-parasitic plants exposed to allelopathic quinones. doi: 10.1111/j.1365-3180.2007.00548.x.

It remains unknown whether host factors are required by broomrape radicle to initiate haustorium and consequently this strategy has not been fully explored. Food Chem. Potential trap crops have been suggested for broomrape weeds (Parker and Riches, 1993). doi: 10.1111/j.1365-3180.1976.tb00406.x, Katan, J. Direct application of strigolactones to the soil has been the subject of intense research. Sci. Ann. Broomrape seed has been documented to last in the soil for at . Several mechanisms underlying this resistance have been described at this stage such as production of gel-like substances within host vessels blocking the transfer of nutrients, host-encoded toxic-compounds delivered into the parasitic tissue though the vascular system and hormonal incompatibility that leads to abnormal haustorial maturation with scarce vascular connections (Fernndez-Aparicio et al., 2008c; Prez-de-Luque et al., 2008, 2009). Weed Sci. orthoceras. doi: 10.1002/adfm.201300053, Fernndez-Aparicio, M., Andolfi, A., Evidente, A., Prez-de-Luque, A., and Rubiales, D. (2008a). The crops affected depend on the host range of the broomrape species considered but in general, those in the Asteraceae, Brassicaceae, Apiaceae, Fabaceae, or Solanaceae such as sunflower, oilseed rape, carrot, faba bean, or tomato among many others, sustain the major attacks (Parker and Riches, 1993). Incorporation of sulfosulfuron and rimsulfuron directly to the soil provides successful control of preattached stages of broomrape weeds (Eizenberg et al., 2012). The flower shoots are scaly, with a dense terminal inflorescence (spike) of 10-20 flowers in most species. seedbank by soil solarization and organic supplementation. Intercropping systems cultivate simultaneously more than one species in close association to take agronomic advantage of biodiversity, competition, and complementarity between them. (2007a). This is not eradication, Hanson said. The https:// ensures that you are connecting to the Benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH) acts as a functional analog of SA and activates defense responses in susceptible hosts leading to lignification of the endodermis and a consequent inhibition to up to 98% broomrape parasitism (Gonsior et al., 2004; Prez-de-Luque et al., 2004; Kusumoto et al., 2007). Convergent evolution of strigolactone perception enabled host detection in parasitic plants. Imazamox application timing for small broomrape (Orobanche minor) control in red clover. Unfortunately this technique represents another example of highly promising broomrape control strategy that has never been validated in field experiments. Planta 227, 125132.

Due to the small size of the seeds and their inability to develop autotrophy, the establishment probability of broomrape seedlings is very low. Broomrape seeds are less capable to recognize crop roots colonized by arbuscular mycorrhizal fungi, Rhizobium leguminosarum or Azospirillum brasilense due to change in the composition of the root exudates in colonized plants (Dadon et al., 2004; Mabrouk et al., 2007a; Fernndez-Aparicio et al., 2009c, 2010b; Louarn et al., 2012). Agronomie 23, 359362. (2007). A simple method for stabilizing and granulating fungi. (2009a). Among the reviewed strategies are those aimed (1) to reduce broomrape seed bank viability, such as fumigation, herbigation, solarization and use of broomrape-specific pathogens; (2) diversion strategies to reduce the broomrape ability to timely detect the host such as those based on promotion of suicidal germination, on introduction of allelochemical interference, or on down-regulating host exudation of germination-inducing factors; (3) strategies to inhibit the capacity of the broomrape seedling to penetrate the crop and connect with the vascular system, such as biotic or abiotic inhibition of broomrape radicle growth and crop resistance to broomrape penetration either natural, genetically engineered or elicited by biotic- or abiotic-resistance-inducing agents; and (4) strategies acting once broomrape seedling has bridged its vascular system with that of the host, aimed to impede or to endure the parasitic sink such as those based on the delivery of herbicides via haustoria, use of resistant or tolerant varieties and implementation of cultural practices improving crop competitiveness. Res. Use of other soil sterilants such as metham sodium, dazomet, and 1,3-dichloropropene have shown different degrees of efficacy but their high cost, complex application and negative environmental effects have prevented their widespread use by farmers (Foy et al., 1989; Goldwasser et al., 1995; Hershenhorn et al., 2009) or conducted to the withdrawal of authorization, at least in some countries. J. Agric. Westwood, J. H., and Foy, C. L. (1999). 111, 579586. Effects of brassinosteroids on conditioning and germination of clover broomrape (Orobanche minor) seeds. According with pot experiments carried out in the tomato-P. aegyptiaca system, deep-plowing bringing the seeds to depth 12 cm will strongly reduce broomrape infection severity in terms of number of parasites, total parasitic biomass, delayed broomrape emergence and prevention of flower initiation and seed set (Eizenberg et al., 2007). Mediterr. For broomrape control, this system seeks the simultaneous cultivation of susceptible host species with inhibitory species of broomrape parasitism.
