Abstract
Regarding to the need of improving the quality and quantity of agricultural products, the science of plant protection has been taken under consideration. Accurate identification and detection of plant pathogens is one of the best ways for successful plant disease management. One of the useful methods is analysis of the volatile organic compounds, which spread from diseased plants. In this method, specificity of the volatile organic compounds and also the factors that affect the identifying of plant diseases and effective methods on these compounds are important. First, these compounds should be collected and then be analyzed. The best method for analysis of these compounds is dynamic sampling followed by gas chromatography and using the proper probes. Although the high costs of the tools make it difficult to apply this method for agricultural purposes, but by using the statistical methods and estimations the costs can be decrease.

 Preventing plant disease damage requires the use of new, powerful, simple and portable tools to quickly diagnose pathogens. Today, biosensor technology  known as a powerful tool for evaluating conventional methods in agricultural sciences. Sensitivity, selectivity and portability of biosensors made it possible to develop them as special tools for rapid analysis of compounds in samples with low concentration. Biosensors have three main components, biological element, transducer and readout system. The most important application of biosensors in plant pathology is rapid detection of plant pathogens, in order to reduce the use of expensive and environmentally-damaging chemicals. This article introduces different types of biosensors and their applications in plant pathology.
