چکیده
KOSTOV, K., R. BATCHVAROVA and S. SLAVOV, 2007. Application of chemical mutagenesis to increase the resistance of tomato to Orobanche ramosa L. Bulg. J. Agric. Sci., 13: 505-513 In this study chemical mutagenesis of tomato seeds with Ethylmethanesulfonate was used to obtain lines with increased resistance to Orobanche ramosa L. The M2 progeny of the mutant tomato plants was screened for the response to broomrape attack in large scale experiment conducted in greenhouse. Sixteen non-infested by the parasite tomato plants were selected. Their offspring was a subject of another screening for broomrape resistance using an artificial polyethylene bags system. As a result of the experiments six lines with significantly increased level of resistance to Orobanche ramosa L., were selected.

This study aimed to investigate the effects of nitrogen fertilizer and a bioherbicide on Egyptian broomrape in a tomato research field at College of Agriculture, Shiraz University, Shiraz, Iran in 2014. Treatments consisted of several levels of nitrate ammonium including 0, 100, 200 and 300 kg ha-1 and a biofertilizer as the first factor and how to use the bioherbicide including soak...
متن کاملBiological Control of Orobanche Ramosa by Fusarium Solani
Orobanche ramosa (broomrape) is a widespread parasitic weed of many Solanaceouse crop species, such as tobacco or tomato, and attaches to many other species, including ornamentals and weeds. It is mainly distributed in the Mediterranean area, central Europe, northern Africa, and the Middle East (Press and Graves, 1995).Many fungi were isolated from diseased Orobanche plants, and some of them pr...
متن کاملGranular formulation of Fusarium oxysporum for biological control of faba bean and tomato Orobanche.
BACKGROUND Orobanche spp. represent a serious threat to a wide range of crops. They are difficult targets for herbicides, and biological control could provide a possible solution. This work therefore aimed to formulate mycoherbicides of Fusarium with adequate shelf life and virulence against Orobanche but safe to faba bean and tomato. RESULTS Only two isolates of Fusarium oxysporum Schlecht. ...
