MEDEIROS, José George Ferreira et al. Health Sanitary and physiological quality of soybean (Glycine max L.) seeds treated with hydrogen peroxide. []. , 42, 4, pp.121-130. ISSN 0871-018X.  https://doi.org/10.19084/rca.18232.

Fungi are the main microorganisms associated with soybean seeds (Glycine max L.), which can cause pathologies both in the field as well as post-harvest and during storage. Hydrogen peroxide (H₂O₂) is an efficient oxidant with proven antimicrobial activity against phytopathogenic agents, mainly associated with seeds. The objective of this study was to evaluate the influence of hydrogen peroxide on the sanitary and physiological quality of soybean seeds. The seeds used were from the cultivar FTS ATHENA RR, which were submitted to the following treatments: control (untreated seeds); commercial fungicide (dicarboximide) and treatments with hydrogen peroxide at concentrations of 0.5; 1.0; 1.5; 2.0; 4.0; 6.0; 8.0 and 10.0% for five minutes of immersion. After the treatments, the seeds were submitted to sanitary and emergency tests in a completely randomized experimental design. Treatment with hydrogen peroxide at concentrations of 2.0; 4.0; 6.0; 8.0 and 10.0% provided an efficient reduction in the incidence of mycoflora associated with seeds (Aspergillus nigerTiegh., Aspergillus flavusLink, Penicillium sp., Fusarium sp., Colletotrichum sp., Cercospora sp. and Rhizoctonia sp.) and positively influenced the emergence and the initial growth of soybean seedlings.
