Pre-harvest crop desiccation (also siccation ) refers to the application of a herbicide to a crop shortly before harvest. The herbicide most widely used is glyphosate, while use of diquat and glufosinate is much more limited. For potatoes, carfentrazone-ethyl is used. Other desiccants are cyanamide, cinidon-ethyl, and pyraflufen. Uneven crop growth is a problem in northern climates, with wet summers, or poor weed control. With desiccation a number of advantages are cited: More even ripening is achieved and harvest can be conducted earlier; weed control is initiated for a future crop; earlier ripening allows for earlier replanting; desiccation reduces green material in the harvest putting less strain on harvesting machinery. Some crop may be mechanically destroyed when crop desiccation machinery moves through the field.

The application of glyphosate differs between countries significantly. It is commonly used in the UK where summers are wet and crops may ripen unevenly. Thus in the UK 78% of oilseed rape is desiccated before harvest, but only 4% in Germany. Other countries have banned desiccation practices, such as Austria and Switzerland.

Applications

Pre-harvest desiccation has been applied to a wide variety of plants including:
