US cancels two OP insecticides
The US EPA has issued a cancellation order for all products based on the organophosphate insecticides, disulfoton and methamidophos. The registrants, Bayer CropScience and Amvac Chemical, requested the cancellations earlier this year ( Agrow No 573, p 17). Most of the cancellations take effect on December 31st 2009, with two disulfoton product registrations ending a year later. The registrants may sell most products until December 31st 2010, with sales of the two disulfoton products continuing until June 30th 2011. Use can continue until stocks are exhausted.
