“…Ginger, however, is subject to various fungal and bacterial pathogens that can cause diseases at different growth stages (Le, Smith, Hudler, & Aitken, 2014;Peng, Yuan, & Gao, 2013;Prasath et al, 2014;Shanmugam, Thakur et al, 2013). Among fungal pathogens, Fusarium oxysporum is especially a major problem in the production of ginger.…”

“…The application of synthetic fungicides is currently the main method for managing postharvest diseases in vegetables, including ginger (Kansal, Dohroo, Preeti, & Neha, 2010;Singh, Rai, & Kumar, 2004). However, stricter government regulatory policies and growing public concerns over environmental and human health issues have generated interest in exploring alternative management methods (Jadhav et al, 2013;Le et al, 2014;.…”

(Le et al, 2014) Soil amendments alter the soil reaction, change the spectrum of soil microflora and thus affect the pathogens existing in soil (Dohroo, 1993;Dohroo and Pathania, 1997). Reduction in soft rot incidence after addition of soil amendments like oil seed cakes, neem cake and other organic matter from various plants in the field was recorded (Sadanandan and Iyer, 1986;Thakore et al, 1987).…”

Ginger (Zingiber officinale Roscoe) is an important spice crop in India, which is also one of the leading producer and exporter of ginger in the world. During cultivation, the crop is severely infected by various diseases of them soft rot, yellows, Phyllosticta leaf spot, storage rot, bacterial wilt, mosaic, chlorotic fleck are important. These diseases reduce the potential yields drastically. The geographical distribution, losses, symptoms, causal organism, disease cycle, epidemiology and host resistance, cultural, biological, chemical and integrated management of above mentioned diseses have been discussed in the present paper.

Endophytic fungi associated with rhizomes of four cultivars of Zingiber officinale were identified by molecular and morphological methods and evaluated for their activity against soft rot pathogen Pythium myriotylum and clinical pathogens. The volatile bioactive metabolites produced by these isolates were identified by GC-MS analysis of the fungal crude extracts. Understanding of the metabolites produced by endophytes is also important in the context of raw consumption of ginger as medicine and spice. A total of fifteen isolates were identified from the four varieties studied. The various genera identified were Acremonium sp., Gliocladiopsis sp., Fusarium sp., Colletotrichum sp., Aspergillus sp., Phlebia sp., Earliella sp., and Pseudolagarobasidium sp. The endophytic community was unique to each variety, which could be due to the varying host genotype. Fungi from phylum Basidiomycota were identified for the first time from ginger. Seven isolates showed activity against Pythium, while only two showed antibacterial activity. The bioactive metabolites identified in the fungal crude extracts include tyrosol, benzene acetic acid, ergone, dehydromevalonic lactone, N-aminopyrrolidine, and many bioactive fatty acids and their derivatives which included linoleic acid, oleic acid, myristic acid, nhexadecanoic acid, palmitic acid methyl ester, and methyl linoleate. The presence of these varying bioactive endophytic fungi may be one of the reasons for the differences in the performance of the different ginger varieties.
