When to Dormant Spray My Peach Trees
I've been told both ways, spray a dormant oil spray on my peach trees within the next few weeks. Also, not to use a dormant oil spray till next spring before it buds.

Dormant sprays should actually be started in winter. Use dormant sprays before green tissue shows in spring buds. Use on days when the air temperature is above freezing. Use a Superior Oil spray for the first dormant spray application in mid- to late winter. Three weeks later make a second application of Superior Oil or Liquid Lime Sulfur.
When spraying trees to control peach borer pests, choose those with lindane endosufan or chlorpyrifos. Sprays should be mixed according to label instructions. They should also be applied so that it runs down the trunk and soaks into the ground around the base. Try not to spray on foliage or any fruit that may still be on the tree. The best time to spray trees for borers is within the first or second week of July and again in late August or September.
