Crop Protection Update

May 11, 2021

The plant growth regulator chlormequat chloride (Manipulator) has been updated to Yellow/Be Informed under Keep it Clean for use on all Barley in Canada (malt, feed and food).   Malting barley had previously been classified as yellow. This classification is a signal to producers to check with their grain buyers before using Manipulator on barley to ensure it will be accepted.  Most malting companies and some grain companies have signaled they will not accept barley treated with Manipulator.  Manipulator is classified as green/acceptable for wheat and oats.
