THE EFFICACY OF MARIGOLD EXTRACT AGAINST NEMATODES: AN EXPLORATORY STUDY FOR A NATURAL LARVICIDE

Abstract

Growing concern over the adverse effects of chemical pesticides on environmental and human health has intensified the search for sustainable alternatives. This study investigated the efficacy of marigold flowers (Tagetes spp.) as a natural larvicide against worm larvae. Marigolds are widely recognized for their pest-repellent properties and contain bioactive compounds with potential larvicidal effects. The objective of this study was to assess the larvicidal activity of marigold extracts against worm larvae and explore their potential role in eco-friendly pest management. Through experimental evaluation and analysis, this research aimed to contribute to sustainable agriculture and environmental preservation by offering a botanical solution for controlling harmful worm populations while maintaining ecological balance. This study focused on formulating a marigold-based larvicide by extracting active compounds from marigold flowers. The flowers were boiled in water, and the extract was incorporated with carbofuran to produce a spray solution. The larvicide was systematically applied to worm populations to evaluate its effectiveness. Worm mortality was carefully monitored over time, and comprehensive data were collected throughout the experimental period. The gathered data were used to assess larvicidal efficacy and to support future research and pest management strategies involving marigold-based larvicides. The results demonstrated that marigold extract exhibited significant larvicidal activity, effectively reducing and eradicating worm populations. The findings indicate that marigold extract has strong potential as a natural alternative to chemical larvicides. These outcomes highlight the feasibility of using marigold-based formulations as an environmentally friendly option for worm control. The findings of this study confirm the potential of marigold flowers as a natural larvicide against worm larvae. Experimental results showed that marigold extracts possess bioactive compounds capable of disrupting larval development and reducing worm populations. This suggests that marigold extract may serve as a sustainable and eco-friendly alternative to conventional chemical larvicides. However, further investigation is recommended to better understand the specific mechanisms of action of marigold extracts on worm larvae. Overall, this research contributes to the growing body of knowledge on botanical pest control and supports the exploration of natural solutions for sustainable agriculture and environmental health. Additional field trials are recommended to validate its practical application in real-world settings.
