Control of Soil-Borne Pathogenic Fungi of Soybean by Biofumigation with Mustard Seed Meal
E.A. Fayzalla, E. El-Barougy and M.M. El-Rayes

Abstract:
Fusarium oxysporum, Rhizoctonia solani, Macrophomina phaseolina and Sclerotium rolfsii are common fungal pathogens to soybean causing damping off, root rot and wilt diseases resulting in serious economic losses. Biofumigation is used as a means to control many diseases by biocidal compounds (mainly isothiocyanates) released from glucosinolates in mustard seed meal which is hydrolyzed during incorporation in the soil. Laboratory, greenhouse and field experiments were conducted to evaluate the efficacy of mustard (Brassica juncea) seed meal against the soil-borne pathogens. Mustard seed meal decreased the linear growth of the tested fungi as compared with the control. The fungicidal effect of mustard seed meal against the tested fungi was demonstrated in pot experiments where diseases were suppressed and plant growth was increased compared to the untreated control treatment. Results of the field experiment (conducted in Ismailia Agricultural Research Station) indicated that mustard seed meal reduced the Disease Incidence (DI) over the control by 69.7% four months after planting. As a reference, the DI reduction was 74.4% over the control when Rhizolex® was used.
