“…However, in 2007 a severe PSR outbreak on ginger was observed and P. myriotylum was reported as a causal agent of the disease (Stirling et al, 2009). Several lines of research have been carried out to control the disease including modifying farming practices, and targeted use of chemical and biological agents.…”

“…Pythium spp. can attack ginger plants at any growth stage in the field as well as at the postharvest stage, and result in losses up to 100% and 90%, respectively (Dohroo, 2005;Stirling et al, 2009). Moreover, because Pythium spp.…”

“…which cause Pythium soft rot (PSR) disease are of the most concern around ginger growing areas throughout the world (Dohroo, 2005). The disease can be very destructive leading to crop failure and the pathogens which are very aggressive can induce visual symptoms within a week of artificial inoculation (Stirling et al, 2009). Pythium spp.…”

“…recorded on ginger flourish in the field when the soil temperature is high (26-30 0 C) and soil moisture is near or at saturation (Lin et al, 1971;Sarma, 1994;Stirling et al, 2009). Such conditions occurred in the ginger growing region of Queensland, Australia during the summer of 2007-08 and resulted in 5-30% losses of immature ginger in some infested fields (Stirling et al, 2009). This was the first formal report of PSR in Australia, and the relatively high losses caused alarm among growers.…”

“…(Atai et al, 2009). Despite its antimicrobial properties, ginger is still a host of at least 24 known plant pathogens (Dake, 1995) including viruses (Nambiar and Sarma, 1974;Nishino et al, 1984;Suryanarayana and Pant, 2008), bacteria (Kumar and Sarma, 2004;Nishijima et al, 2004;Stirling, 2002), oomycete (Sharma and Jain, 1977;Stirling et al, 2009; and fungi (Gao et al, 2006;Overy and Frisvad, 2005;Rai, 1993;Sharma and Jain, 1977;Stirling, 2004).…”

BACKGROUND Rhizome rot, caused primarily by Fusarium oxysporum, is one of the most destructive diseases leading to significant loss in ginger worldwide. The loss can be greatly reduced by proper disease management practices steered by accurate and early diagnosis of pathogens. Pathogen detection at an early stage of infection can also reduce the incidence of disease epidemics. Classical methods are often time consuming, relying on culturing the putative pathogens and the availability of expert taxonomic skills for accurate identification, which leads to the delayed application of control measures. The development of a simple, rapid, sensitive and cost‐effective point‐of‐care diagnostic tool is thus one of the major research priorities for rhizome rot. RESULTS The 65 kDa, immunoreactive protein band was selected as a diagnostic marker and was subjected to MS analysis followed by blastp. Based on blast result, a synthetic antigenic peptide was synthesized, and used to generate pAbs. The peptide‐specific antibodies were used to develop a colloidal gold immunochromatographic assay (ICA). The sensitivity, specificity, and accuracy of ICA were 92.59%, 81.25%, and 90%, respectively. The ICA has a visual detection limit of 2.122 μg mL−1 for infected rhizome samples and 5.065 μg mL−1 for leaf samples with optimal detection time within 5 min. Moreover, the ICA also detected early stage infected samples, of which 71.42% (50/70) were true positives. CONCLUSION Findings from this study indicated that the assay can be utilized as a tool for the investigation of rhizome rot infection in field samples. © 2019 Society of Chemical Industry
