How can desiccants best be used ahead of the fall harvest?

As farmers are getting to work on harvest, many are using desiccants to spray down crops to get them to dry out quicker.

Those chemicals come with a bevy of rules and regulations, explains Saskatchewan Ministry of Agriculture Crop Extension Specialist Mackenzie Haldun.

"There is a minimum number of days that must pass after applying a product, such as a desiccant before a crop can be swapped or straight cut, and this is known as a pre-harvest interval. These pre-harvest intervals, also known as PHIs, are in place to ensure that the levels of chemical residue on the harvested crop are within acceptable limits.”
