How Desiccant Use Impacts Grain Trade
Protecting the quality and reputation of cereal crops starts with responsible crop management before harvesting. Growers are encouraged to use only registered desiccants on wheat, barley, and oats and to follow all label instructions carefully.
Using products that are not approved for cereal crops can create serious challenges. Improper applications may result in pesticide residues that exceed acceptable limits in domestic and international markets. This can lead to rejected grain shipments, trade disruptions, and reduced market opportunities.
Grain shipments are routinely tested throughout the supply chain to ensure they meet residue standards. The following approved practices help growers produce grain that meets customer expectations and supports continued market access.
An important step is selecting the correct product for the intended purpose. Growers should understand the difference between desiccation, which helps dry crop material before harvesting, and pre-harvest weed control. Using a product for the wrong purpose may increase the risk of residue issues.
Some crop protection products may be approved for use on other crops but are not registered for wheat, barley, or oats. Applying these products to cereal crops can result in residue detections that may not meet import requirements in key export markets.
Growers should also remember that glyphosate is a weed control product and not a desiccant. It should only be used according to approved label instructions and recommended application practices.
Following label directions is essential for effective and safe crop management. Label rates, application timing, and pre-harvest intervals are designed to help ensure product performance while keeping residue levels within acceptable limits. Applying products above approved rates or harvesting too soon after application can increase compliance risks.
Before making an application, growers should also review grain contracts and buyer requirements. Certain buyers may have additional restrictions regarding crop protection products even when those products are registered for use.
