Cuscuta campestris Yunck. and Viscum album L.) extracts against some plant pathogenic fungi}, journal={Turkish Journal of Weed Science}, volume={20}, pages={61–69}, year={2017}, author={Şin, Bahadır and Kadıoğlu, İzzet and Onaran, Abdurrahman}, keywords={Plant pathogenic fungi, Parasitic plant extracts, Antifungal activity}, abstract={Because of the adverse effects of pesticides used today, it has become important to find new alternative control methods. In this study, antifungal activities of three parasitic plants species, Orabanche ramosa, Viscum album and Cuscuta campestris, were investigated against Alternaria solani, Monilinia fructigena, Fusarium oxysporum f. sp. radicis-lycopersici (FORL) plant pathogens. Methanol extracts derived from parasitic plants were used in antifungal activity studies. These studies were conducted with the agar plate method. Extract doses of 2, 5, 10 and 20 mg ml-1 used against plant pathogens. Experiments were set up four replicates and repeats 2 times. Percentage of mycelial growth inhibition (MGI) and lethal doses were determined according to results. According to these results, each plant extract showed noticeable antifungal activity. As the amount of the dose increased, the activity rates increased. As a result of antifungal activity studies, the highest effects were observed at 20 mg ml-1doses of plant extracts against A. solani, with rate of 90% in C. campestris, 78% in V. album against M. fructigena, and 76% against FORL in C. campestris. LD90 values were calculated as 230.6 to 58.4 in O. ramosa, 128.6 to 51.3 in V. album, and 43.5 to 38.9 mg ml-1 in C. campestris against plant pathogens. In addition, with the data collected from this study, the utilization of methanol extracts obtained from parasitic plants in control of plant pathogens were investigated for the first time. As a result, the identification of the activities of antifungal substances in the environment will facilitate to the discovery of cheaper and environmentally friendly alternative substances}, number={1}, publisher={Türkiye Herboloji Derneği}
