In these systems, copper is ground into micro sized particles and suspended in water rather than dissolved, as is the case with other copper products such as ACQ and copper azole. There are two particulate copper systems in production. One system uses a quat biocide system (known as MCQ) and is a derivative of ACQ. The other uses an azole ...

[5] Copper naphthenate is the only non-restricted use wood preservative in widespread use for "heavy duty" commodities such as utility poles, railroad crossties and timbers, pilings and fence posts.
Copper pesticide is applied as a contact protective foliar spray, so it remains deposited on leaf surfaces. A small concentration of copper ions may be taken up by plants as essential nutrients. Copper foliar sprays are also applied to correct plant copper deficiency. [8] Excess absorbed copper ions can kill sensitive cells in copper sensitive ...
