Most species are primarily subterranean and appear aboveground only to reproduce. Due to their achlorophyllous nature, broomrapes are constrained to obtain their nutritional resources by feeding off other plants using the haustorium, an organ unique in parasitic plants through which the parasite diverts water and nutrients from the host (De Candolle, 1813; Kuijt, 1969; Musselman and Dickison, 1975; Westwood, 2013).

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). doi: 10.1038/nature03608, Albrecht, H., Yoder, J.

Refined formulations and encapsulations of fungal propagules increase efficacy in biocontrol by reducing desiccation or microbial competition (Amsellem et al., 1999; Quimby et al., 1999; Kroschel et al., 2000; Mller-Stver, 2001; Aybeke et al., 2015). (1999). (2002). Tempting as it may be to keep an infestation secret, the consequences of risking spread of broomrape could be disastrous. Third, broomrape underground attachments do not take herbicides from the soil but only systemically from the host and therefore, this strategy is limited to systemic herbicides applied to herbicide-resistant crop varieties that do not metabolize the herbicide into inactive forms. Biol. Manschadi, A. M., Kroschel, J., and Sauerborn, J. 43, 6371. Weed Res. Application of phosphate or nitrogen to deficient soil reduces broomrape parasitism on clover and tomato (Southwood, 1971; Jain and Foy, 1992). 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.

The effectiveness of amino acids as broomrape inhibitors has not been proved in real field conditions but field application of amino acids has been effective to manage other parasites such as plant-parasitic nematodes (Zhang et al., 2010).

Thats what the Israelis do; they went from 70 percent yield losses to very modest losses they can live with.. Orobanche crenata in Ethiopia. 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). parasitism on amino acid composition of carrot (Daucus carota L). Besides the effects of fertilization management on pre-attached broomrape stages described in previous sections, high soil fertility can induce crops to endure broomrape parasitism by helping the host to maintain a favorable osmotic potential that reduces the parasitic sink strength (Gworgwor and Weber, 1991). Understanding the key processes of host recognition, haustorium development and maturation and metabolic regulation of the parasitic sink allow virulence predictions and the design and implementation of highly calibrated, feasible, and durable control strategies leading to the arrest of broomrape parasitism minimizing simultaneously environmental impact and yield losses. doi: 10.1046/j.1365-313x.2001.00971.x, Mauro, R.
