Abstract

Weeds are among the most important factors that cause economic losses in crop production. Weeds cause yield and quality losses by competing with crops and negatively affecting them with their allelopathic effects. In addition, some weeds live as parasites on crop plants. The study aimed to determine parasitic weed species and their incidence in Siirt province of Turkey. Survey studies were carried out in a total of 105 points representing the province, in 2018-2019. A total of 7 parazitik weeds species (Orobanchea egyptiaca Pers., Orobanche crenata Forssk., Orobanche ramosa L., Cuscuta approximata Bab., Cuscuta campestris Yunck., Viscum album L. and Loranthus europaeus were identified in the region. The crops and weeds hosts of the parasitic weeds were also determined. It has been observed that the incidences of Orobanche species were quite high especially in lentil and tomato fields and were cause significant economic losses. It has been also observed that integrated weed management strategies are needed to prevent yield losses by parasitic weeds in the region. However, considering the deficiency of the knowledge of producers on the subject, it was concluded that farmer awareness programs are urgently needed.
