Özet:

Organisms such as bacteria, fungi, viruses, and nematodes cause yield and quality loss in agricultural production. Especially the control of fungal pathogens is challenging. The fact that chemical pesticides used in the control of these pathogens are not environmentally friendly, increases the importance of alternative methods such as the use of biopesticides. Biopesticides that are not relatively harmful to human health and the environment are generally secondary metabolites from plants, viruses, bacteria and fungi. Fungi produce various mixtures of volatile organic compounds (VOCs). More than 300 different fungal VOCs including aldehydes, alcohols, benzene derivatives, phenols, heterocycles, hydrocarbons, ketones, cyclohexanes, thioesters, and thioalcohols have been described. The interaction between fungal VOCs and plant pathogens pose an ecofriendly alternative to chemical pesticides. Researches have shown that fungal VOCs can be used effectively with their inhibitory or repellent aspect against the plant pathogens and insect pests as a biopesticide. In this review, the possibilities of using fungal VOCs against different plant diseases and pests as an substitute to chemical pesticides within the scope of biological control are summarized.
