ABSTRACT

Control of Spodoptera litura in the tropical sugarbeet is a critical issue for sustainable agriculture. The purpose of this fieldexperiment was to assess the efficacy of botanical and non-chemical techniquesagainst S. litura to identifyecologically viable management alternatives. Spodoptera litura responded best to a neem oil solution at aconcentration of 3.0 mL/L. In terms of insect infestation, the plot treatedwith neem oil outperformed the untreated control plot. The infection rates forplants, leaves, and beets were 5.66/plot, 5.33/plant, and 11.00/plot,respectively. In terms of larvae decrease over control, the plot treated withneem oil had the greatest effectiveness (84.33%), followed by pheromones, whichhad an efficiency of 80%. Plants treated with neem oil showed the highest Brixand Pol values (17.61% and 12.62%, respectively). Weight per beet was lowest inthe control plot (690.33 g), and highest in the best treatment (791.33 g). Itclearly shows that when insect infestation grows, beet yield falls. The controlplot was unable to effectively resist S.litura, resulting in unhealthy sugar beet output. In contrast, eco-friendlytechniques such as NPV spraying, Bio Neem Plus®, Tracer 45SC (spinosad), handpicking, light trap, and polythene mulching trap outperformed the control plot.
