Crop desiccation

Pre-harvest crop desiccation is the application of an agent to a crop just before harvest to kill the leaves and/or plants so that the crop dries out from environmental conditions, or "dry-down", more quickly and evenly. Crop desiccants (not to be confused with a chemical desiccants) include herbicides and defoliants, used to accelerate the natural drying of plant tissues. Desiccation of crops through the use of herbicides is practiced worldwide on a variety of food and non-food crops.
