Cranberry blog - July 25th

As you may be aware, PMRA is currently re-evaluating all of the OP and Carbamate pesticides and they have recently reviewed Phosmet (Imidan) and have come up with some interim measures to mitigate potential occupational exposure risks in order to allow for continued registration.

During the summer of 2011 they will be conducting inspections at cranberry operations across Canada to verify new compliance measures introduced on the label as a result of this re-evaluation. They will focus on:

1) new post-application personal protective equipment requirements;(long-sleeved shirt, long pants and chemical-resistant gloves) is required for
critical post-application activities performed by workers within 14 days of phosmet application. Additionally, the same PPE is required for thinning activities which takes place within 30 days of application.

2) Restricted-entry intervals (REI) into treated areas; There is a 3 Day REI for Imidan use in Cranberry and a 30 day PHI.

3) Posting treatment notification; Double notification (i.e., written notice on posted signs and verbal notification to those re-entering the field) is required for field workers indicating that the area has been treated with phosmet and that phosmet is a cholinesterase inhibitor. This should include a brief description of the signs and symptoms of cholinesterase inhibition and
ways to minimize exposure. Wash stations are required to be available for re-entry workers.

All information can be found on the newest Imidan label and all labels should be read carefully before applying any pesticide.
