According to the federal communique, in August 4, 2017, the EPA issued regulations to exempt the Beta Cyclodextrin and Methyl Ethers as the maximum residue limits of pesticide adjuvants in crops.
The application for this exemption is submitted by Lewis and Harrison, LLC company on behalf of Wacker Chemie AG. The new regulations come into force on the date of promulgation and are sought for the end of October 3, 2017.
Some of the original reports are as follows:
This regulation establishes an exemption from the requirement of a tolerance for residues of beta cyclodextrin, methyl ethers（CAS Reg. No. 128446-36-6） when used as an inert ingredient （stabilizer and solvent） in pesticide formulations applied to growing crops pre-harvest limited to a maximum concentration of 40% by weight in the pesticide formulation. Lewis and Harrison, LLC, on behalf of Wacker Chemie AG submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act （FFDCA）， requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of beta cyclodextrin, methyl ethers that result from applications of pesticides consistent with the conditions in EPA regulations.
