Abstract

The invention discloses a bacteriostasis method of camphor leaf essential oil. The essential oil is extracted by steam distillation or simultaneous distillation and extraction, the distilled liquid is separated from oil and water, and the oil part is dried with anhydrous sodium sulfate to obtain the camphor leaf essential oil. , and the obtained camphor leaf essential oil is used as an active ingredient to inhibit phytopathogenic fungi. When the volume ratio of camphor leaf essential oil is 7:25, the antibacterial rates against Fusarium oxysporum, Thielavia aescini and Phomopsis are not less than 80%, 90% and 61% respectively.

Description

technical field

[0001] The invention relates to a plant source fungicide, in particular to a bacteriostasis method of camphor leaf essential oil. Background technique

[0002] Plant diseases are the enemy of agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), the average annual loss of production due to plant diseases is 10% to 15% of the total output (Wu Chuanwan et al., 2004). At present, the main method of controlling plant diseases is chemical fungicides. However, due to the potential harm of chemical pesticides to human health, environmental pollution, impact on non-target organisms and the development of resistance to plant pathogens, the development of chemical pesticides has been restricted from various aspects (Zhao Jihong and Li Jianzhong, 2003). Since plant essential oils are naturally derived, relatively safe to the human body, environmentally friendly, and have diverse biological activities...
