What is the best crop stage to apply Reglone Ion in canola?

Crop staging is critical to get application timing right. Because Reglone Ion is a true desiccant, it will not mature the crop, and green seed levels will not decrease after application.

To properly stage the crop:

1. Look for brown colouring in the upper pods and stems. You should not see any yellow or green.
   
   • When checking the crop for colour change, be sure to look at the top 10% of pods. If these top-most pods aren’t brown, none of the others will be either. 
     
   • Keep an eye out for pods that have changed colour due to sunburn. If pods are wrinkly, or are brown with green seeds inside, they are likely sunburnt and not mature enough for Reglone Ion application.
     
2. Listen for a rattle in your pods. Mature seeds are loose in the pod and rattle when the plant is shaken.
   
3. Strip out seeds from several areas of the field. The crop is ready when 90% of each plant has seeds that have turned completely brown.

If more than 10% of the field is not ready, plan to treat those less mature areas separately.

A crop is not ready for Reglone Ion if…

• Pods are yellow or green at the top of the plant and feel leathery.
• You hear little or no rattling when plants are shaken.
• More than 10% of the seeds are green or freckled (showing seed colour change, rather than brown seed).
• More than 10% of a field with variable maturity is not ready and you don’t want to go back in later to treat it separately.
