Abstract

Ginger is a major spice in India which also has many medicinal properties. It is affected by various biotic and abiotic stress among them soft rot is a major disease caused by fungi. It causes about 70-90 per cent of crop loss if unchecked, even though many synthetic fungicides are available for control of the disease keeping the degradation of the environment due to excess use of chemicals, The present study had been taken up to identify some eco-friendly alternatives to synthetic fungicides has been screened. This study was carried out with different plant extracts viz., Pimento dioca, Murraya koenigii, Adathoda visica, Piper longum, and Zingiber officinalis. The results showed that the highest anti-fungal (Fusarium sps & Pythium sps) activity was recorded in Allspice (87.84 %&84.31%) followed by Curry leaf, Long-pepper, Adathoda, and Ginger. Quantitative studies are carried out for the analysis of phenols and anti-oxidant activity which was recorded highest in allspice (143.88 % and 87.52 %) among the all-plant extracts. This study concluded that the allspice plant extract had the potential to control this fungal disease.

Keywords

Ginger (Zingiber officinale Rosc.), Quantitative Studies, Secondary metabolites, DPPH, Phenols, Anti-oxidant and Antifungal

Conclusion

The extracts are screened for phytochemicals which showed the presence of phenols, flavonoids, terpenoids, saponins, tannins, and alkaloids. Quantitative studies are carried out for the analysis of phenols and anti-oxidant activity the plant extracts are rich in phenols and anti-oxidant activity showed significant antifungal activity against Pythium aphanedermatum and Fusarium solani. Due to the richness of bioactive compounds in the five botanical extracts, they can be used as a source of substances with the antifungal potential of low toxicity for the management of soft rot disease in Ginger. For future control of disease organically or through IPM these are the best alternatives.
