Health Canada proposes some neonic restrictions

Health Canada is proposing some restrictions on the use of three neonic pesticides for horticultural production but they would still be registered for use on field crops such as corn and soybeans.

Meanwhile the department will continue working with the U.S. Environmental Protection Agency and the State of California on the impact of the pesticides on pollinators and insects.

Proposed decisions for thiamethoxam and clothianidin will be published in mid-2018. So far, the department says clothianidin and thiamethoxam do not pose risks to pollinators and their use will continue on a restricted basis.

A phase-out of foliar application to orchard trees and strawberries as well as municipal, industrial and residential turf sites would be proposed. Pre-bloom application would be reduced from two to one for cucurbit (cucumbers, squash, etc.) vegetables. There would be additional protective label instructions for cereal crop uses.

Proposed changes to the way thiamethoxam can be used include phase-out of foliar and soil applications to ornamental crops that will result in pollinator exposure as well as on berry crops, cucurbit crops and fruiting vegetables and orchard trees. Foliar application to legumes, outdoor fruiting vegetables, and berry crops would no longer be permitted before or during bloom.

As the result of additional information supplied on clothianidin and thiamethoxam products was required, Health Canada is proposing that these products be granted a three-year registration.
