Producers must declare plant growth regulator Manipulator use upon delivery

The product cannot be used on exports destined for the U.S. until maximum residue limits are established

Farmers will be required to declare whether they have used the plant growth regulator Manipulator on their wheat as of Aug. 1, the Manitoba Wheat and Barley Growers Association says in a “producer alert” issued June 4.

The association said the new declaration will apply to deliveries to the majority of grain handling facilities in Canada to ensure crops that have been treated with the product are not exported to the U.S.

Chlormequat chloride, the active ingredient in Manipulator, has been approved for use in Canada and the majority of export customers, except for the U.S., where it is still being evaluated.

“In this transition time, MRLs (maximum residue limits) for shipments to the United States are technically zero and unattainable for any production treated with chlormequat chloride,” the MWBA release says. ”

As a result, Canadian grain buyers who export will require a signed declaration indicating use of chlormequat chloride in order to manage supply and ensure that only untreated production is shipped to the United States prior to MRLs being established.

Based on producer declarations, grain companies will reserve the right to not accept chlormequat chloride production while accumulating stocks for a United States-destined sale. The MWBA stresses farmers understand that a signed declaration is a legally binding document.

“Any intentional or unintentional mistake in declaration traced back through retained samples will expose individuals and their farms to significant liability.”

“Producers and grain exporters must work together to respect and protect our market relationship with the United States,” said Fred Greig chair of the Manitoba Wheat and Barley Growers Association.
