The Efficacy of Plant-Based Ginger Essential Oil Fungicide for the Management of Some Selected Fungi

Abstract

Recent research demonstrates that the number of virulent phytopathogenic fungi continually grows, which leads to significant economic losses worldwide. Several methods are currently available for the management of phytopathogenic fungi. Since 1940, synthetic fungicides have been typically used to control phytopathogenic fungi. However, the substantial increase in the development of fungal resistance to these fungicides in addition to the negative effects caused by the fungicides on the health of animals, human beings, and the environment calls for the exploration of several new strategies of fungal control by scientists from all over the world. This work aimed to determine the efficacy of using ginger essential oils for the management of some fungal diseases in plants. The minimum inhibitory concentration (MIC) was conducted using broth microdilution assays where different concentrations (100, 150, 200, 250, 300, 350, and 400 mg/mL) of the extract and control are added to a series of tubes containing a standardized microbial inoculum (x10⁶) and incubated at 25 °C. The results of antifungal activity showed that ginger essential oil has an effect on the two tested organisms for all the concentrations. At 100 mg/mL, the inhibition of 31 mm at day 3 for Rhizoctonia solani. It can be concluded from this work that ginger essential oil showed strong antifungal activity against the test organism
