FUNGICIDE RESISTANCE IN PLANT PATHOGENIC FUNGI

The most effective method to control of diseases which caused by fungal microorganisms in plants is using of fungicide. However it couldn’t be obtained adequately or it could be obtained no disease control with fungicides because of several causes. One of them is the development of resistance against the fungicide in a fungal pathogen. Fungicide resistance is described as the stable, inheritable adjustment by a fungus to a fungicide, resulting in a less than normal sensitivity to that fungicide. Most likely, resistance occurs a result of genetic mutations. According to type of these genetic mutations, resistance shows differences. This paper aims at giving types of resistance and how does develops resistance, the factors which are effective in development of resistance and according to risk of resistance development of fungicides groups with fungal pathogens.
