Oh TS, Koo HM, Yoon HR, Jeong NS, Kim YJ, Kim CH - Plant Pathol. J. (2015)

Bottom Line: From study of antifungal actions on the rice sheath blight by using the extract of Ginkgo biloba outer seedcoats, we found that the extracts of Ginkgo biloba outer seedcoats of all treatment concentrations had inhibited the rice sheath blight.As a result investigating the antifungal activity by separating polysaccharides from G. biloba outer seedcoats, it showed that the clear zone of 14 mm or more was formed at the concentration of 250 mg/l or higher.Based on these results, we concluded that the G. biloba outer seedcoat is a natural substance with the antifungal activity on the rice sheath blight.

ABSTRACT
From study of antifungal actions on the rice sheath blight by using the extract of Ginkgo biloba outer seedcoats, we found that the extracts of Ginkgo biloba outer seedcoats of all treatment concentrations had inhibited the rice sheath blight. Among them, the most effective concentration was 250 mg/l at which the growth of microbe was 26 mm and even at the packaging test, when sprayed the G. biloba outer seedcoats at the level of 250 mg/l, the damage rate of the rice sheath blight was identified as 13%. As a result investigating the antifungal activity by separating polysaccharides from G. biloba outer seedcoats, it showed that the clear zone of 14 mm or more was formed at the concentration of 250 mg/l or higher. Based on these results, we concluded that the G. biloba outer seedcoat is a natural substance with the antifungal activity on the rice sheath blight.

f1-ppj-31-61: Growth inhibition effect in Rhizoctonia solani Kuhn AG-1(IA) of hexaconazole emulsion and Ginkgo biloba outer seedcoat extract on PDA culture medium as growth photos from 7th day after inoculation of hypha, A: Untreated control plot, B: hexaconazole emulsion (250 mg/l), C: Ginkgo biloba outer seedcoat extract (500 mg/l), D: treatment levels that G. biloba outer seedcoat extract (250 mg/l) is mixed.

Mentions: It has been known that because the Ginkgo biloba outer seedcoat that currently has been discarded contains ginkgolic acid, it has the antifungal activity for the tubercle bacillus. Recently, the researches on the antimicrobial activity against several plant diseases have been progressed by using this antifungal activity against various plant diseases, and also its antifungal activity against the plant diseases caused by the fungi began to be known. In this experiment, we had tested the antifungal activity against the rice sheath blight by using G. biloba outer seedcoats, and consequently, the bacterial activity of G. biloba outer seedcoats against the rice sheath blight was identified. The results are as shown in Fig. 1 and Table 1.
