Is there a difference between desiccation and pre-harvest herbicide application?
Yes, and the use is a matter of preference. True desiccants are harvest management tools that rapidly kill above ground growth of crops and weeds. This allows for rapid dry down and an earlier harvest. Desiccants will not give long-term weed control and any late moisture may cause both the weeds and the crop to start to re-grow. Pre-harvest glyphosate application is generally used for perennial weed control. It can be used as a harvest management tool for dry down but the effects take much longer to appear. Pre-harvest glyphosate is a good tool for long-term control of perennial weeds such as Canada thistle, quackgrass, toadflax and dandelions.

Desiccation with products such as RegloneTM in pulses allows the crop to mature evenly for a faster harvest, which can reduce the risk of losing quality. Desiccation will not help immature seed to mature. Another reason for using Reglone TM in peas is for the control of wild buckwheat. Glyp
