Biocontrol Agents and Organic Matters for Meloidogyne incognita Infection of Beta vulgaris L. | Research Letter
Currently, the utilization of M. incognita-resistant cultivars is regarded as a nematode management strategy that is both economically feasible and ecologically benign, with no discernible risks to human health. The primary aim of the investigation was to assess the effects of screening for root-knot nematodes, specifically Meloidogyne incognita, on the development, biochemistry, and pathology of beetroot and spinach cultivars. The research investigations detailed in the dissertation were carried out both in vitro and in vivo within the Department of Botany at Aligarh Muslim University, located in Aligarh (U.P.). The present study selected Beta vulgaris L. Cv. Ruby Queen and Spinach (Spinacea oleracea L. cv. All Green) as experimental plants, belonging to the Amaranthaceae family. The statistical analysis of the trials was performed utilizing the one-way analysis of variance (ANOVA) method and the R statistical software. The results indicate that the effects of M. incognita on various plant growth parameters (e.g. shoot and root length, shoot and root fresh weight, and number of leaves per plant), biochemical parameters (e.g. total chlorophyll and carotenoid contents), and pathological parameters (e.g. number of eggmasses per root, number of eggs per eggmass, nematode population per 250 gm soil, and root-knot index) were not consistent across all cultivars that were analysed.
