Abstract:
Background and Objective: Sesame is an oil crop that has been cultivated in Egypt for hundreds of years. Sesame crop suffers from various soil-borne diseases. Charcoal root rot caused by Macrophomina phaseolina (Tassi.) Goid, is considered one of the main destructive diseases of this crop. The current research was conducted to evaluate the efficacy of biofumigation using the Brassica crops (rocket, cauliflower and radish) on root rot disease of sesame. Materials and Methods: Naturally infected roots of the diseased sesame plants were collected in two successive seasons (2017 and 2018), three biofumigant crops i.e. radish (Raphanus sativus), cauliflower (Brassica oleracea var. Botrytis) and rocket (Eruca sativa) were used as compared with the fungicide Rhizolex-T on mycelial growth of Macrophomina phaseolina in vitro. Obtained data were statistically analyzed using one-way analysis of variance MSTAT. Results: In the first season the cauliflower treatment was not significantly different from that of the fungicide Rhizolex-T in the field experiment. Obtained data showed that Cauliflower biofumigation and Rhizolex-T treatments have resulted in the lowest disease severity levels (2.000, 2.000) 80 days after transplanting. Moreover, Cauliflower-biofumigation and Radish-biofumigation showed the lowest severity levels 2.000, 2.000 at 80 days after transplanting in the second season respectively. There were no significant differences between all tested treatments 60 days after transplanting in 2017. Conclusion: The results of this research demonstrated that biofumigation using the studied brassica crops may provide high efficacy of safe and economical control of charcoal rot of sesame.
