“…These fungi cause discoloration and rotting, affecting viability as well as commercial and nutritional value because of increased fatty acid content, oil rancidity and heating of the seed mass, which increases the respiratory rate and accelerates deterioration (Machado 1988;Nóbrega and Suassuna 2004;Bellettini et al 2005;Borém et al 2006;Santos et al 2013). Aspergillus flavus is generally the most destructive species in peanuts (Hocking and Banks 1991).…”

“…For the 'Cavalo' variety, there was an increase in DSI% with inoculation of F. graminearum, from 5.7% to 12.1% in NS and from 5.0% to 18.0% in AS (Table 2). Bellettini et al (2005) evaluated the pathogenicity of fungi associated with peanut seeds, 'Tatu' cultivar, and verified that 35% of seedlings inoculated with Fusarium oxysporum Schlecht. presented lesions in the collar and roots region.…”

The objective of this study was to evaluate the pathogenicity of Fusarium graminearum on creole bean seeds, quantify the incidence of root lesions and damping off in seedlings, and evaluate the reduction of germination and seed vigor. Two varieties of creole beans, 'Cavalo' and 'Chumbinho', were collected from a family property located in the municipality of Severiano de Almeida, state of Rio Grande do Sul, Brazil. The treatments evaluated were: seeds not inoculated (T1) and inoculated (T2) with F. graminearum macroconidia suspension at a concentration of 8.0 x 10 5 macroconidia mL-1 , and the appearance of lesions and influence on vigor and germination were observed. The variety 'Cavalo' proved to be more susceptible to F. graminearum, expressing vigor reduction, incidence of root lesions and damping off. The variety 'Chumbinho' expressed no vigor reduction, although it has occurred reduced incidence of damping off. Regarding root lesions, the 'Chumbinho' variety compares to the variety 'Cavalo'.

“…are commonly found infecting peanut seed (Barrozo et al, 2012;F. Santos et al, 2013) and among these, some like Aspergillus niger and Fusarium oxysporum may cause pre-and post-emergence damping-off, resulting in direct damage to the crop (Bellettini, Endo, Miglioranza, & Santiago, 2005).…”

Peanut seed can be infected by pathogen diseases that adversely affect the oil crop’s value chain. Ozone gas (O3) can be an alternative for the control of fungal diseases due to its high oxidizing potential. In this study, we investigated the effects of O3 exposure time on physiological and health characteristics of seed from three peanut cultivars. Seed from peanut cultivars Granoleico, IAC OL3, and IAC 503 were analyzed for their health (blotter test) and physiological potential (germination, first count, and seedling length) after exposure to O3 for 0, 1, 8, and 16 h. Peanut seed physiological quality and health differed among cultivars. Exposure of seed from peanut cultivars IAC OL3, IAC 503, and Granoleico to O3 at a rate of 600 mg h-1 did not affect the development of normal seedlings as measured by the first count and germination, but seedling length increased, decreased, or was not affected in cultivars Granoleico, IAC 503, and IAC OL3, respectively. Also, O3 did not eradicate fungal infections in peanut seed treated with O3 at a rate of 600 mg h-1 for up to 16 h, but the incidence of the fungus Rhizopus sp. in seed from cultivars IAC OL3, Granoleico, and IAC 503 increased, decreased or was not affected, respectively, after 8 h.
