I grew up in Peach country in the Central Valley of California. The farmers there always used (so I did too) a mixture of Copper Sulfate and Horticultural oil. Make sure you find liquid Copper Sulfate as the powder never really mixes well and clogs the sprayers. You have to constantly agitate the oil/copper solution to keep it in solution or you can add an emulsifier.
Never use this mix in warmer months or you will damage or kill your trees.
Both the products you mention are for use in the warmer months for killing insects, not over-wintering eggs. Hmmm... maybe that was your question. I assumed, because I am looking at a foot of snow outside, that you were spraying dormant spray.
