Spraying Nectarines

Question

I planted a couple white nectarine trees last year and now have small fruit growing, in the spring I sprayed with copper and also horticultural oil, but at this time of the summer should I spray anything else and is it bad to spray when there is fruit growing? Thanks -Dean

Answer 1

Usually, treatment with oils or copper should be done during dormancy, or according to the instructions label. Each product can have a different potency and set of application rate and time. I would AVOID a summer application, however!
