The Effectiveness of Various Insecticides Against Bagworm Pests (Mahesa corbetti) Mortality in Oil Palm Produtive Plants in Marbau District, Pernatian Village, PT Umada Plantation

Palm oil plays a crucial role in the vegetable oil industry, particularly in palm oil production. Bagworms, a major pest affecting oil palm plants, cause significant harm to leaves and decrease plant productivity. These caterpillars can rapidly reproduce and spread extensively if not effectively managed. Sipermetrin and Dimehipo are two types of insecticides utilized to combat bagworm pests on oil palm plants. This study employs a descriptive analysis approach, involving the collection of primary data through field observations and pest censuses, as well as secondary data from previous pest censuses within the company. Data collection was conducted meticulously to ensure precision and relevance to actual field conditions. The objective of this study is to assess the extent of bagworm pest infestation and evaluate the efficacy of Sipermetrin and Dimehipo insecticides in controlling these pests on oil palm plants at PT Plantations in Umada Pernantian "A", Marbau sub-district, North Labuhan Batu Regency. The findings of the study revealed that the application of Sipermetrin was more successful in managing bagworm pests compared to Dimehipo. The mortality rate of bagworm pests with Sipermetrin usage ranged from 80-90%, while with Dimehipo, it only reached 40-50%. Therefore, Sipermetrin has demonstrated greater efficiency in controlling bagworm populations and preserving the health of oil palm plants, offering a superior solution to the pest issue in these plantations.
