Currently, the new formulation of Sevin is an insecticide that is good choice for home orchard use. The new Sevin has Zeta-Cypermethrin as the active ingredient. Also as mentioned earlier in the thread don’t use spray equipment that has been used to spray herbicides since it’s very difficult to get all of the herbicide residue out.
I would take a look at Alan’s spray schedule it covers a lot on spraying fruit trees. I think you will find it helpful.
