    Abstract: High productivity of agriculture goods is closely associated with the use of fungicides to reduce losses caused by the fungal plant diseases. However, appearance of resistant population of pathogens to several commercial fungicides is a common phenomenon that requires control. There is, therefore, need for developing novel fungicide compounds that ... Show More
