PENGARUH PENGGUNAAN PESTISIDA DAUN SIRSAK (Annona muricata L.) TANAMAN AJERAN (Bidens pilosa) DAUN JERUK NIPIS (Citrus aurantiifolia) UNTUK MENGENDALIKAN HAMA KUTU HITAM (Neotoxoptera formosana) PADA TANAMAN BAWANG DAUN (Allium fistulosum)

The purpose of this study was to determine the ability of botanical pesticides from soursop leaves, ajeran plants, and lime leaves to control black aphid pests on spring onion plants. This study was conducted from May 2024 to August 2024 in Jorong Simpang, Nagari Selayo Tanang Bukik Sileh, Lembang Jaya District, Solok Regency, West Sumatra with an altitude of ± 1500 meters above sea level. The design used was a Randomized Block Design (RAK) with 4 groups and 8 treatments. The treatments used consisted of: P0 (No treatment), P1 (Soursop leaf extract), P2 (Ajeran plant extract), P3 (Lime leaf extract), P4 (Soursop extract + ajeran extract (1:1)), P5 (Soursop extract + orange extract (1:1)), P6 (Ajeran extract + orange extract (1:1))., P7 (Soursop extract + ajeran extract + orange extract (1:1:1)). The data were analyzed statistically, if the calculated F P ≥ F table 5% was obtained, the Duncun New Multiple Range Test (DNMRT) was carried out at the 5% level. The results of the study showed that the highest average plant height (37.03 cm) was found in treatment P5, the highest leaf length (28.24 cm) and the highest number of leaves (9.13 strands) were found in treatment P1, the highest weekly mortality (81.87%) and the highest total mortality (44.91%) were found in P4, the highest intensity of pest attacks was found in P0 (63.75%), the highest wet weight of plants (87.88 g) and the highest production weight (351.5 tons/ha) were found in treatment P5.
