This treatment in the lab mimics the soil conditions in climatically suitable regions for broomrape such as Mediterranean non-irrigated agrosystems where the onset of warm and wet season coincides with the growth of juvenile stages of many annual crops (Lpez-Granados and Garca-Torres, 1996; Grenz and Sauerborn, 2007).

M., Uygurc, F. N., and Sauerborn, J. The concept of trap crops refers to the cultivation of crop species whose root exudates exhibit high germination-inducing activity on broomrape seeds, but these species do not become infected because they are resistant to later stages of the parasitic process indirectly leading to the killing of the young broomrape seedlings due to the lack of proper host. This paper reviews relevant facts about the biology of broomrape weeds, the key mechanisms they employ to attack crops and the control methods already developed or in development that directly target those mechanisms. 93, 10391051. doi: 10.1614/WS-D-11-00113.1. Until now, difficulties of purification at industrial scale have hampered the field experimentation with such metabolites (Vurro et al., 2009) despite their interesting potential. Environ.

Wegmann and L. J. Musselman (Obermarchtal: Eberhard-Karls Universitat), 110114. 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). doi: 10.1007/s11627-007-9054-5, Aly, R., Plakhin, D., and Achdari, G. (2006). The long-term approach to parasitic weeds control: manipulation of specific developmental mechanisms of the parasite. Bagley urged growers and pest control advisors to be vigilant in avoiding spread of this weed to new fields. 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). They are attempting to learn if a timely application of an herbicide at a rate high enough to stunt the broomrape, but low enough to spare the tomatoes, can be an effective strategy to minimize crop losses.

Broomrape Eradication is High Priority for UC Researchers, 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, The host range of broomrape, in addition to tomato, covers a number of economically important rotational crops in the Central Valley: safflower, sunflower, carrot, bell pepper, several, Hanson and fellow researchers UC Davis assistant professor, Vergara presents findings on farmer-to-farmer education in Panama, Melotto named AAAS fellow for work in plant defenses against bacteria, Yasay accident report released by Davis Police, Poudel wins AAUW International Fellowship, Our leadership-Plant Sciences Executive Committee, Guidelines for Departmental GSR Annual Progress Report and Final Report, Plant Sciences Graduate Student Travel Award, Plant Sciences Teaching Assistantship (TA) Application (temporary link). A quantitative model for loss of primary dormancy and induction of secondary dormancy in imbibed seeds of Orobanche spp. 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). However, the overall productivity of the host-parasite system is also reduced due to the shorter growing period being detrimental for crop yield. Weed Res.

(2009). 42, 464469. This strategy requires a careful calibration of doses and timing depending on the host crop and underground phenology of broomrape determined by local conditions and crop (Hershenhorn et al., 1998, 2009; Eizenberg et al., 2006). Another strategy to induce suicidal germination of broomrape seed bank could be the use of gibberellin agonists. 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. Potential trap crops have been suggested for broomrape weeds (Parker and Riches, 1993). Being deprived of the initiation of autotrophic mode of life, the growth of broomrape seedling toward the host is only sustained by water absorption and remobilization of reserve nutrients from the seed perisperm and endosperm (Joel, 2000; Joel et al., 2012). The following sections and Table 1 review the major feasible control measures for broomrape control. (2001). 36, 113121. doi: 10.1146/annurev.pp.41.060190.001015. The chemical characteristics of the barriers of resistance to broomrape penetration have been extensively studied in Fabaceae crops (Prez-de-Luque et al., 2009) and are reviewed in this article in Section Resistant Crops to Broomrape Invasion..
