Detection of Diseased Plants by Analysis of Volatile Organic Compounds

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.
