I have read the threads and some we literature on dormant sprays and I am trying to come up with a spray plan and would like feedback on what i am doing is right or wrong.
These are the diseases and pest that I experienced this past year - fire blight on 2 apple trees, bacterial canker on a cherry tree, bacterial spot on peaches (until the squirrels ate them), aphids on my apples trees, plum curcilio and moth damage to peaches. Where applicable I want to spray for these diseases/pests and do preventive treatments for things like peach leaf curl. Most of my trees are young but have 30 to 40 trees (I lost count) and another 20 some trees on my fathers property.
I have apples, peaches, Asian pears, one European pear, one plum and several young grape vines.
Reading the forums it seems that Copper and lime sulfur are the common dormant sprays.
I already have Kocide 3000 (for Copper) and plan on buying Rex Lime Sulfur -
The rates are listed at 10.25 to 12.8 oz per gallon of water for the lime sulfur (Sevin Springs site) and the spray guide on this site shows using 2 Tbsp/gal for Kocide 3000.
Reading the forums it seems that some people also use horticultural oil combined with copper and lime (for dormant sprays only).
For the horticultural oil I plan to use - Monterey Horticultural Oil - 2.5 - 5 Tbsp per gallon of water.
Finally it seems that i should I use a sticker Nu-Film-17 - 1/2 tsp per gallon
I plan on applying when when the trees are dormant (fall) and at green tip (spring) - please correct me if I am wrong on this.
Nothing I read indicates the water ph level matters on these products so i will use straight tap water.
Any feedback on my dormant spray plan would be greatly appreciated.
