Post-harvest diseases are one of the main causes of reducing the supply of fresh garden products. The occurrence of post-harvest diseases can affect the quality and limit the shelf life of fresh horticultural products. Currently, strict ordinances apply to import agricultural products. One of these regulations is the minimum residual pesticide residue in the fresh food sector. On the other hand, in developed countries, the consumption of organic products is increasingly popular among consumers, and for organic production, a natural factor is needed to eliminate plant microorganisms as post-harvest treatment. The use of essential oil in the agricultural sector of the country and its use on all kinds of fruits is a new approach. Unlike chemical compounds, vegetable essences do not have side effects for the consumer and do not have a harmful effect on the environment. The use of essential oils can reduce the detriment resulting from pathogenesis and control some post-harvest diseases of agricultural crops.
