Nghiên cứu nhằm mục đích đánh giá hiệu quả kháng nấm Leveillula taurica gây bệnh phấn trắng trên cây ớt chuông của hệ nhũ nano bản chất lipid chứa tinh dầu tỏi (Ne-GA), tinh dầu quế (Ne-CI) và tinh dầu neem (Ne-NE) ở điều kiện in vitro. | TNU Journal of Science and Technology 227 05 84 - 91 INVESTIGATION OF IN VITRO ANTIFUNGAL EFFECT OF LIPID-BASED NANOEMULSIONS ENCAPSULATING GARLIC OIL CINNAMON OIL AND NEEM OIL ON LEVEILLULA TAURICA CAUSING POWDERY MILDEW ON BELL PEPPER PLANTS Nguyen Minh Hiep Tran Thi Ngoc Mai Dalat nuclease research institute ARTICLE INFO ABSTRACT Received 10 01 2022 This study aims to investigate the in vitro antifungal effect of lipid-based nanoemulsions of garlic oil Ne-GA cinnamon oil Ne-CI and neem oil Revised 08 4 2022 Ne-NE against Leveillula taurica causing powdery mildew disease on Published 13 4 2022 bell pepper plants. Firstly lipid-based nanoemulsions Ne encapsulating essential oil were prepared by a combing method of homogenization and KEYWORDS sonication. Next in vitro antifungal effect of Ne-GA Ne-CI and Ne-NE was carried out by agar disk method using bell pepper leaves at dilution Nanocarriers concentration of 25 50 100 200 400 and 600 times. The results showed Leveillula taurica that the nano-formulations of essential oils were successfully prepared Garlic essential oil with a particle size of less than 140 nm and zeta potential of more than - 30 mV. The results also indicated that Ne-GA had a higher antifungal Cinnamon essential oil activity than Ne-CI and Ne-NE. In addition at a dilution of 400 times Neem essential oil Ne-GA still exhibited the high disease-preventing and disease-treating effectiveness of and 90 respectively. Therefore this study indicates that essential oil-encapsulated lipid-based nanoemulsions can be widely applied in clean and sustainable horticulture to protect bell pepper plants from Leveillula taurica.
