Copper Compounds Subject to Registration Review: This table lists the copper pesticides subject to all regist

ongoing product reregistration actions, as well as the chemical properties and uses of these copper compounds. T

updated chemical property information listed in Table 3 and 4 of the Revised RED for Coppers (May 2009). The individual products may vary slightly from those shown depending on manufacturing processes, molecular weigh

calculated. Molecular weights were calculated from atomic weights as stated in the 90th edition of the CRC PresChemistry and Physics.
