Use of Antioxidants as Green Chemicals to Control Soybean Diseases and Scaling up the Yield and Quality

M.A. Elwakil , M.A. El-Metwally and S.I. Abd Elhamid

Background and Objective: Soybeans are a globally important crop consumed by both man and animal. Worldwide production in 2019/2020 was 358 million metric t. The current research aimed at testing the possible correlation between treating seeds and plants of soybean with antioxidants and retreading the disease severity that occurred by the pathogenic fungi. Materials and Methods: Soybean seeds collected from different locations in Egypt were used to isolate seed-borne plant pathogenic fungi. Antioxidants were selected for further testing that produced the greatest growth reduction of target fungi from in vitro tests. Effective antioxidants were then applied as seed treatments (soaks) and sprays to soybean plants in field tests. Plant growth parameters and seed yield and quality were then recorded. An analysis of variance was performed on the collected data using CoStat 6.311. Means were compared using Least Significant Difference (LSD) according to Duncan. Results: Soaking seeds in salicylic acid (3 g L–1), citric acid (6 g L–1), benzoic acid (6 g L–1) and a combination of these before planting, followed by two plant spray applications at the same concentrations reduced disease incidence and increased yield by 48%. Conclusion: The results showed a strong correlation between use of antioxidants and decreased disease incidence and resulted in increased yields. This research suggests the potential for benefits using antioxidants as seed treatments and plant sprays to control soybean diseases resulting in increased yields of high quality seeds.
