Abstract

BACKGROUND

Potatoes are extremely important compared to other vegetable crops. Several species of fungi cause severe damage to different components of the plant (leaves, stems, and tubers), leading to significant losses during cultivation and even after harvest. In the framework of the investigation for alternative methods against the proliferation of these fungi, the present work focuses on the study of the antifungal effect of essential oils of some plants that could be used to solve these problems without the use of harmful chemical substances.

AIM AND PURPOSE

This study aims to discuss the chemical composition of essential oils of Artemisia herba alba and Ammoides verticillata and evaluate their in vitro and in vivo antifungal activities in order to prevent fungal diseases of potatoes and replace chemical pesticides that cause neurodegenerative diseases.

METHODS

Essential oils extracted from the aerial parts of the plants and were analyzed by gas chromatography-mass spectrometry (GC/MS) and tested individually and in combination for their antifungal effects against , and , by the radial growth technique.

RESULTS

The essential oil of was mainly composed of hydrocarbon monoterpenes (80.8%), while the oil of was mainly composed of oxygenated monoterpenes (54.4%). The study on the antifungal effect of essential oils showed that essential oil of was more effective against (64.40%) than A. flovus (41.10%) and (53.30%), and the oil of was more effective against A. flavus (54.40%) and (42%) . While the combination of these two essential oils of and gave excellent results, i.e., 100% against and and 94.40% against and provided an in vivo protection to the potato in the range of 80% to 90% against the three fungi.

CONCLUSION

and individual and combined essential oils are very effective antifungal biocides that can be used as an alternative to chemical pesticides to prevent their harmful effects on health.

摘要

背景

与其他蔬菜作物相比，土豆极其重要。几种真菌会对植物的不同部位（叶片、茎和块茎）造成严重损害，导致在种植过程中甚至在收获后造成重大损失。在研究替代方法来控制这些真菌扩散的框架内，本工作重点研究了一些植物精油的抗真菌作用，这些精油可以在不使用有害化学物质的情况下解决这些问题。

目的和宗旨

本研究旨在讨论艾蒿和弯管花精油的化学成分，并评估其在体外和体内对、和的抗真菌活性，以预防土豆真菌病并替代导致神经退行性疾病的化学农药。

方法

采用气相色谱-质谱联用技术（GC/MS）对植物地上部分提取的精油进行分析，并采用径向生长技术单独和联合测试其对、和的抗真菌作用。

结果

精油主要由单萜烃组成（80.8%），而精油主要由含氧单萜组成（54.4%）。对精油抗真菌作用的研究表明，精油对的抑制效果（64.40%）优于对的抑制效果（41.10%）和的抑制效果（53.30%），精油对的抑制效果（54.40%）优于对的抑制效果（42%）。而这两种精油的组合，即和，则产生了极好的效果，即对和达到 100%的抑制率，对和达到 94.40%的抑制率，对三种真菌的活体保护率在 80%到 90%之间。
