Plant releases volatile chemicals compounds in air through which plant interacts to both biotic and abiotic communities these are called plant volatiles. Nearly one-fifth of the carbon fixed by plant every day is released as volatiles. Majority of plant volatiles are derived from: terpenoids, fatty acid catabolites, aromatics, amino-acid derived products and alcohols. Plant volatiles serve various functions in plants ranging from signal transduction to plant defense. Volatiles compounds released by plants are one of the fastest exploited weapons, with respect to minimizing the yield losses and providing tolerance to various stresses. Plant volatiles have several physiological and ecological functions for plants. Many of the volatile terpenes are nonspecific toxins active against a wide range of organisms (bacteria, fungi, plants and animals). Agricultural crops are having less volatile emission making them susceptible to various biotic and abiotic stress. Keeping in mind the ecological functions of volatiles, the aim should be to optimize the emission patterns by choosing right cultivars for individual land areas with specific cultivation challenges. Plant volatiles are also a source of intra plant and inter plant interactions. In response to attacks, plants produce a wide array of volatile organic compounds which have multiple functions as internal plant hormones as well as play a crucial role in the communication between plants and the associated community members, such as other herbivores, phytopathogens and the natural enemies of herbivores.
