Delegate label expanded

The Pest Management Regulatory Agency (PMRA) has announced the approval of a minor use label expansion registration for Delegate insecticide for suppression of peach tree borers on stone fruit, crop group 12-09 and for suppression of chestnut weevils and hazelnut weevils on tree nuts, crop group 14-11 in Canada. Delegate insecticide was already labeled for use on a wide variety of crops in Canada for control of several insects.

 

These minor use projects were submitted by Ontario as a result of minor use priorities established by growers and extension personnel.
