Plutella xylostella L. is the main pest that attacks Brassicacea plants, especially broccoli (Brassica oleracea L. var. Italica). The attacks caused by these pests are sometimes so severe that the crops fail to harvest. This condition is very detrimental, so farmers often take control measures using synthetic insecticides to control pests. However, the use of synthetic insecticides has a negative impact on the environment, including soil contamination, killing natural predators, accumulation of chemical residues on plant parts, and causing pests to become resistant to insecticides. Therefore, it is necessary to have alternative control techniques using organic materials without using synthetic insecticides that are safe for the environment, namely by using vegetable insecticides such as citronella (Cymbopogon nardus L.). The citronella plant contains essential oils which can be used to control plant pests (OPT)
