Results of this study showed that 26 species belonging to 12 genera were isolated from dodder stems ,flowers and seeds .The fungi Exserohilum rostratum, Bipolaris bicolor, Altrenaria longipes , A.tenuissima, Acremonium restrictum, Bipolaris australliensis and Cladosporium oxysporium were recorded for the first time on dodder in Iraq. However the two species E. rostratum and B. bicolor were recordrd on dodder for the first time in the world . The fungi A.terreus , E. rostratum ,T. viride , A. alternata and B. bicolor inhibited the percentage of dodder seed germination up to 10, 13.4 ,16.7,16.7 and 23.4 % respectively. The fungal exudates also effect dodder seed germination , the exudates of E. rostratum reduced the germination percent to 13.4%. The pots experiment showed that treatment of T. viride led to increase the plant hight up to 29.98 cm .T. viride also gave more leaves and branch number reached to 28.56 leaves per plant. The results also explained that T. viride with 350 ppm glyphosate led to increase the infection of dodder.The experiment showed that T.viride gave a higher hight of plant reached to 31.34 cm,. T.viride led to increase the number of leaves up to 28.67 , while dodder led to reduce the number of and branches. Which reached to 13.34 and 5.34respectively .The infection of dodder also increased when T. viride was applied .It reached 91.67 %. | ||
