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 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.
