In early May, the EPA published a proposal to revoke tolerances for three insecticides used on almonds. The proposal allows existing stocks of Thiodan (endosulfan) to be used until July 31, 2012, after which the current tolerances for almonds and almond hulls would be revoked.
For Supracide (methidathion), EPA proposed to allow sales of stocks through Dec. 31, 2014, and use of existing stocks until they are exhausted. However, as the registrant thinks any existing stock will be used up by 2016, EPA proposed revoking tolerances for nuts and for almond hulls as of Dec. 31, 2016.
The remaining registrations of Penncap-M (methyl parathion) have been canceled. EPA proposed allowing the use of existing stocks through Dec. 31, 2013, with the tolerances to be revoked the same day.
Any of the above listed insecticides can be used within the given time frames as long as the use is listed on the label.
Growers with any of these products on hand should use them up before their use becomes illegal. EPA is taking comments on these proposed end-of-use dates and tolerance revocation dates through July 5, 2011.
