Abstract

The fungi Penicillium digitatum and P. italicum represent the main global economic loss to the citrus industry during postharvest stage. Nowadays, the use of fungicides is increasingly restricted due to their carcinogenic, teratogenic, high residuality, long degradation period, environmental contamination, increased pathogen resistance, among others. Natural antimicrobial compounds could be a safe and viable option to minimize disease losses facing the industry. In this study, we evaluated in vitro the activity of tymol, carvacrol and commercial mandarin oil (Italian Mandarin) at concentrations of 40 and 50 ppm using the agar diffusion method and microbiological testing. All the essential oils evaluated for both fungi, showed an inhibition rate between 50% and 100%, and the effect was higher at doses of 50 ppm. This effect was followed by inhibition of sporulation and germination. Carvacrol showed the higher antifungal activity for both fungi studied. P. digitatum showed a greater sensitivity to the effect of the essential oils evaluated compared to P. italicum. Commercial mandarin essential oil can be an alternative to the control of postharvest diseases caused by Penicillium sp. in plant products

本研究的目的是评价柑橘精油对青霉菌生长的抑菌活性。

指状青霉和意大利青霉是全球柑橘产业采收后的主要经济损失。目前，杀菌剂因其致癌性、致畸性、高残留、降解期长、环境污染、致病菌抗性增强等特点，其使用日益受到限制。天然抗菌化合物可能是一种安全可行的选择，可以最大限度地减少行业面临的疾病损失。在本研究中，我们利用琼脂扩散法和微生物学测试，评估了40和50 ppm浓度下tymol、carvacrol和商用柑桔油(意大利柑桔)的体外活性。所有精油对这两种真菌的抑制率都在50%到100%之间，并且在50ppm的剂量下效果更高。其次是抑制产孢和萌发。香芹酚对两种真菌均有较高的抗真菌活性。相对于意大利菊，指连菊对精油效果的敏感性更高。商品柑桔精油可作为控制植物产品中青霉菌引起的采后疾病的替代产品

期刊介绍： The journal Ciencia y Tecnología Agropecuaria (Science and Agricultural Technology) is a four-monthly scientific publication edited since October 1996 by the Corporación Colombiana de Investigación Agropecuaria - Agrosavia. The journal publishes articles on diverse thematic areas typical of the agricultural sector (multidisciplinary), written in Spanish or English, especially from Latin American and Caribbean researchers. The contributions that apply for the journal must be original and unpublished. The articles are reviewed by national and international peers (peer review). The journal is non-commercial and open access, this means that it doesn’t charge for the reception and/or publication of articles in both, its printed and digital version. The journal is aimed at the scientific community of the agricultural sector in Latin America and the Caribbean.
