“…(Gaur 1990). The application of P. lilacinum in combination with neem cake improved nematode control, plant growth and yield in nematode infested cardamom plantations (Ali, 1987;NRCS, 1993;Eapen and Venugopal, 1995;Mathew, 2007;Devasahayam et al, 2015). Sheela (2007) found that P. lilacinum reduced root knot nematodes by 48.5 to 57% in pot culture studies and by 19.7% in field studies.…”

Investigations were made to study the effects of three nemato-pathogenic fungi viz. Purpureocillium lilacinum, P. lilacinum + neem cake, Pochonia chlamydosporia and Trichoderma sp. as well as two synthetic insecticides (cartap hydrochloride and carbosulfan) against the Root-knot Nematodes (RKN) of cardamom at the farmers’ fields in three locations of Idukki district, Kerala, India during 2016- 2019. Results revealed that the combined application of P. lilacinum with neem cake gave maximum reduction of typical symptoms of infestation like the leaf narrowing (6.42%) and root knot formation (1.32 nos.) followed by P. chlamydosporia with 8.04% narrowed leaves and 1.83 root knots. The application of P. lilacinum and neem cake in combination (0.82 kg/plant and 2.99) followed by P. chlamydosporia (0.71 kg/plant and 2.71 recorded highest yield and Benefit Cost Ratio, respectively). Bio-control agents are therefore efficient and environmentally safer for managing the RKN in cardamom. Future studies can be directed to focus on the compatibility and efficiency enhancement of these bio-agents with organic amendments.

Tamarind, a tropical fruit-bearing tree, is essential for food, pharmaceutical, and industrial applications. Advancements in tamarind production technology are needed to ensure sustainable cultivation and efficient processing. This review focuses on innovative cultivation practices, breeding strategies, pest management, post-harvest practices, and value addition. It explores intercropping, agroforestry, and water-efficient irrigation systems to maximize land utilization and water resources. Integrated pest management strategies, such as biological control and organic pesticides, are proposed to reduce chemical dependency, minimize environmental impact, and maintain ecological balance. Post-harvest technology, including innovative harvesting, cleaning, storage, and processing techniques, is evaluated to maintain product quality and shelf life. The review also examines the economic viability and value addition opportunities within the tamarind industry, identifying potential product diversification and reducing the carbon footprint.

Development of a colloidal gold strip‐based immunochromatographic assay for rapid detection of Fusarium oxysporum in ginger

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
