Spray schedule for home orchards.
I have a few each of apple, pear, and nut trees that I spray rather sporadicaly with dormant (Lime-Sulphur) and insecticides. My spraying reference is "Extension Circular 631, revised April 1982. Is a more current one available?
The most recent version of EC 631 was published in 2010. You can download it here: http://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/18027/ec631.pdf
