Although broomrape pre-vascular connections benefits from host nutrients, the growth of broomrape in its way toward vascular cylinder is mainly sustained by consumption of seed reserves (Aber et al., 1983; Joel and Losner-Goshen, 1994; Joel, 2000). In addition, accumulation of toxic phenolic compounds at the infection point can be observed in some resistant varieties. As a consequence, except when deeply infested, the farmer (and thus the market) will not retain a solution that has economical negative drawbacks. Solar heating (solarization) control of soilborne pests. (2009). Biol. 109, 181195. Parasitic plants Striga and Phelipanche dependent upon exogenous strigolactones for germination have retained genes for strigolactone biosynthesis. 14, 227236. 100, 537544.

However, exogenous application of GA alone is not sufficient to promote broomrape germination (Takeuchi et al., 1995; Chae et al., 2004) and strigolactone-mediated ABA catabolism in conditioned seeds is required to trigger germination (Lechat et al., 2012). Weed Sci. doi: 10.1016/1049-9644(92)90021-5, Abbes, Z., Kharrat, M., Delavault, P., Chabi, W., and Simier, P. (2009). Delaying sowing date has, however, a general drawback by reducing yield potential under normal development so that plant breeding program tend generally to favor long lasting cultivars with early sowing dates.

Fenugreek root exudates show species-specific stimulation of Orobanche seed germination. 7:135. doi: 10.3389/fpls.2016.00135. (2009). Preventing the movement of parasitic seeds from infested to non-infested agricultural fields, by contaminated machinery or seed lots, is crucial (Panetta and Lawes, 2005). Weed Res. However, selecting for high phenolic varieties is likely to induce many other side changes altering agronomic performance. Besides the difficulty of selectively controlling broomrape in the form of host-attached parasite, eradication of broomrape seed bank is extremely difficult due to prolific production of parasitic seeds, their easy dispersal, physiological dormancy, seed longevity, and germination synchronized with specialized range of host cultivation. doi: 10.1016/S0261-2194(99)00070-8, Antonova, T.

Therefore, decisions on the date of sowing has to be well-adjusted in order to balance the loss of productivity due to shorter growing period with gain of productivity due to reduced parasitism. It is a prolific seed producer. Host plant resistance against broomrapes (Orobanche spp. Plant Cell Physiol. J. Bot. A variety of methods have been developed to specifically neutralize broomrape pre-attached development though the majority of them are not commercially implemented because they are still at the stage of development or have not proved enough efficiency or applicability for large scale crops.

(A) Fructification and dehiscence of capsules containing mature seeds; (B) microscopic view of a seed (size ranging 0.22 mm) that undergoes sucessive dispersal, primary dormancy and annual release of secondary dormancy; (C) broomrape embryo does not develop morphologycaly identified cotyledons or shoot meristem and upon host-induced germination, only a radicle emerges from the seed with the function of searching and contacting the host root; (D) upon haustorial induction, the radicle stops elongating and a single terminal haustorium is differentiated. Z. Planzenphysiol. Many other interesting examples of trap crops emerged from a root exudates screening of important crops (Fernndez-Aparicio et al., 2009b). Thidiazuron stimulates germination and ethylene production in Striga hermonthica comparison with the effects of GR24, ethylene and 1-aminocyclopropane-1-carboxylic acid. Broomrape high fecundity, with thousands of seeds released per broomrape plant (Figures 2A,B), multiplies the chances of the next generation to encounter a host and achieve successful parasitism (Parker and Riches, 1993).

The second possibility to increase rotation efficacy for broomrape control is to include catch crops, which are crops that also induce high broomrape germination but they are not resistant to it. Jain, R., and Foy, C. L. (1992). eCollection 2022. The first attempts to deplete parasitic weed seed bank was made by Johnson et al. (1998). Germinating seeds of the root parasite Orobanche aegyptiaca Pers. This study evaluated the relationship between small broomrape devel-opment and temperature with red clover as a host plant. This parasitic weed, unable to produce its own chlorophyll, survives only by attaching to the roots of a host plant, often with severe consequences.

Branched broomrape is so destructive in tomatoes that if it is detected in a growers field, quarantine regulations require that the crop be destroyed and the field be disked under, and common sense dictates that a grower rotate out of host crops for many years, said Brad Hanson, UC Cooperative Extension weed specialist, Department of Plant Sciences, UC Davis. The majority of strategies aimed to manage autotrophic weeds do not necessarily work for broomrapes and those that provide a degree of success for broomrape need to be optimized for each broomrape-crop species combination, local environmental conditions and broomrape population. 23, 407413. doi: 10.1093/aob/mcm032, Ben-Hod, G., Losner-Goshen, D., Joel, D. M., and Mayer, A. M. (1993). Four broomrape features define the post-attachment herbicidal strategy in comparison with non-parasitic weeds. It is best recognized by its yellow-to-straw coloured stems completely lacking chlorophyll, bearing yellow, white or blue, snapdragon-like flowers. Bot. Cleavage of sucrose into glucose and fructose doubles the osmotic potential of the parasite. Urea has no detrimental effects in plants but it is toxic to broomrape pre-attached stages probably exercised via ammonium after broomrape urease hydrolyses urea into ammonium.

These thumbnail pictures have links to larger photographs and . Commercially available as Bion, field doses of 0.8 kg ha1 are recommended to inhibit P. ramosa parasitism in hemp and tobacco (Gonsior et al., 2004), crops for which resistant varieties are not available. As the broomrape seeds are long-lived and difficult to detect, infested fields are usually quarantined to prevent further spread. Both have red eyes and a feathery crest. Acta 108, 4755. doi: 10.1016/j.fcr.2011.09.003, Fernndez-Aparicio, M., Moral, A., Kharrat, M., and Rubiales, D. (2012b). Soil fumigation with methyl bromide has been proved one of the most effective methods to eradicate broomrape seed bank, but this chemical has been banned from use due to its toxic effects on the environment (Joel, 2000; Hershenhorn et al., 2009). Control the Striga conundrum. Reda, F. (2006). The opposite agricultural practice deep-plowing, has been suggested to bring seeds of parasitic weeds to a depth with less oxygen availability and therefore a reduction in its germination capacity (Van Delft et al., 2000). Phytochemistry 72, 624634. Prez-de-Luque, A., Fondevilla, S., Prez-Vich, B., Aly, R., Thoiron, S., Simier, P., et al. 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). Org. The harvest of infested fields or blocks, because of the biology of this weed and its standing as a California Department of Food and Agriculture Class A status, is extremely ill-advised., (Article by Bob Johnson, Sacramento reporter. In recent years, a new, aggressive race designated as race F (called biotype D in Russia) has . Engineered host crops harboring herbicide-resistance transgenes have not yet been commercialized for broomrape management (Gressel, 20092). The stimulatory capability of crop root exudates is defined by the qualitative and quantitative content of germination-inducing factors and varies across crop species and cultivars. Broomrapes are plant-parasitic weeds which constitute one of the most difficult-to-control of all biotic constraints that affect crops in Mediterranean, central and eastern Europe, and Asia. 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).
