Abstract

This study aimed to determine the effect of liquid smoke from flamboyant wood waste on the extent of pest attacks on pakcoy (Brassica rapa L.) and to identify the most effective concentration. The experiment was conducted at the Oesao Experimental Garden, Politeknik Pertanian Negeri Kupang, using a Completely Randomized Design (CRD) with five treatments (0%, 1%, 3%, 5%, and 7%) and three replications. Data were analyzed using ANOVA followed by Duncan’s multiple range test at the 5% significance level. The results showed that five types of pests attacked the pakcoy plants, namely the lady beetle (Hippodamia convergens), armyworm (Spodoptera litura), black bug (Paraeucosmetus pallicornis), green grasshopper (Atractomorpha crenulata), and wood locust (Valanga nigricornis). Treatments with 5% and 7% concentrations significantly reduced pest attacks, with 5% being the most effective in suppressing damage at 16, 23, and 30 days after planting. These findings highlight the potential of flamboyant wood liquid smoke as an eco-friendly botanical pesticide for sustainable pakcoy cultivation.
