Title : The effects of application of dry skin of Virginia tobacco stems extract on population and attack intensity of leaf miner pests (Liriomyza sp.) On potato plants (Solanum tuberosum l.)
Abstract:
The aim of this research was to determine the effect of different concentrations of botanical pesticide extract from Virginia tobacco stem waste applied on potato plants (Solanum tuberosum L.) to control leafminer pests (Liriomyza sp.). This experiment was conducted in Sembalun village, East Lombok district from July to September 2024. The parameters observed were pest population, pest infestation intensity, presence of pest enemies, number of tubers and weight of tubers. The design used was a Randomized Block Design (RAK) consisting of 6 treatments with 4 replicates namely P0 (control, P1 (abamectin), P2 (tobacco extract 30 ml/1000 ml water), P3 (tobacco extract 40 ml/1000 ml water), P4 (tobacco extract 50 ml/1000 ml water) and P5 (tobacco extract 60 ml/1000 ml water). Botanical pesticide extract from waste Virginia tobacco is effective in suppressing the population and intensity of attacks by leaf miner pests. The efficacy of using the botanical pesticide from tobacco stem waste extract at P2 with a concentration of (30 ml/L) was found to be significantly different from P0 (control). Botanical pesticides thath contain 60ml/L extract show that did not differ significantly from the chemical treatment (abamectin) with regard to population suppression, attack intensity and yield of potato tubers (Solanum tuberosum L.).
