Abstract: Bipolaris oryzae is the causal agent of rice brown spot disease and is responsible for significant economic losses. In order to control this disease, three phenolic antioxidants were tested (salicylic acid, benzoic acid and hydroquinone). The antifungal activity of the tested substances were investigated against B. oryzae at different concentrations in vitro, as well as the efficacy of their exogenous application in controlling rice brown spot disease under field conditions. In vitro, benzoic acid or salicylic… Show more

“…These results show that brown leaf spot disease of rice can effectively be controlled by various fungicides. The same has been reported by Shabana et al (2008) for fungicides and anti-oxidants against brown leaf spot. Similarly, the results of this study have also been supported by the findings of Savary et al (2000) who reported that brown leaf spot caused yield loss up to 5% along with qualitative loss and can be managed by the use of fungicides.…”

“…S2; Supplemental Table S2). Benzoic acid itself exhibits antifungal activity, and pretreatment of plants with this compound increases plant resistance to fungi (Khan et al, 2001;Williams et al, 2003;Shabana et al, 2008). Similarly, benzoic acid levels increase in response to both bacterial and viral infection (Shapiro and Gutsche, 2003;Matsuura et al, 2009).…”

“…Brown spot disease also leads to a reduction in the total photosynthetic pigments in rice leaves (Abdel-Fattha et al 2007;Shabana et al 2008). The content of leaf pigments and membrane integrity are crucial for maintenance of the net CO 2 assimilation rate (A) in plants (Matsuda et al 2004).…”
