Fumigants are necessary to prepare many planting sites for the healthy growth of trees, vegetables, crops and ornamental plants. According to a study by Markets and Markets, changing farming practices and the need to reduce post-harvest losses are some of the factors motivating farmers to experiment with fumigant use.  Further, rigorous pest free certification standards make it necessessary for some farmers to utilize fumigants in order to meet the requirements for movement of the plants or harvested crop to other regions. CPRI has released a number of reports on the widespread use of fumigants along with natural methods to enhance the quality of plants and crops. These reports highlight the various fumigants that different stakeholders are using based on the region and kinds of crops grown.
