| Abstract | ||||
| SCLEROTIUM ROLFSII (S. rolfsii) causes root rot disease in several crops including Cicer arietinum (chickpea) that results in low yield. In vitro experiments on fungicides, vitavax and monceren T, and essential oils, clove and mint oils, were conducted to control root rot disease of chickpea caused by S. rolfsii. The treatments resulted in 80 % suppression of root rot disease. Gliocladium virens (G. virens) and Gliocladium deliquescens (G. deliquescens) were effective as biocontrol agents against S. rolfsii. The results showed that these treatments greatly reduced the root rot disease in chickpea. In this study, the effect of gamma irradiation at doses 0, 0.25, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 kGy on the pathogenecity of G. virens and G. deliquescens against S. rolfsii were investigated. The results revealed that gamma irradiation increased the pathogenecity of G. virens and G. deliquescens against S. rolfsii. | ||||
