I planted the following fruit trees in Spring 2012 in my Southern Maryland yard and although the pollination seems to be working great, I think I need to start spraying right away for what I think is Black Spot on pears, possibly Bacterial Spot or Coryneum Blight on the apricot (I think the leaves looked scraggly from shothole and that tree dropped its leaves before the other fruit trees - so bottom line I want to hit it with a good fungicide), and bugs (Castleton Euro plum gets aphids bad every year before the lady bug arvae demolish them and Japanese Beetles were awful in 2013):
Apricot - Tomcot (citation rootstock)
J. Plums - Methley, Satsuma, Shiro
E. Plum - Castleton (least vigorous of all my trees, even on Myro rootstock . . .)
Plumcot - Spring Satin
E. Pears - Potomac, Blake’s Pride, Seckel
A. Pears - 2, can’t recall the varieties but they are from Edible Landscaping
*I don’t grow any apples, cherries, or peaches.
I just looked at my trees yesterday night and although the buds are clearly visible, I didn’t see any green yet so I’m guessing they are in the pre-bud-break stage at the moment. And it is going to be pretty cold this week (lows in the teens and highs in the 20s) so I should have a little time until bud break.
From reading a bunch of old Gardenweb threads where Scott was a major contributor (e.g., http://forums.gardenweb.com/discussions/1449914/my-orchard-calendar?n=16), it seems that I should:
Apply dormant oil spray very soon for bug control.
Apply copper + nuFilm17 sticker solution (or can I just add the copper to the dormant oil??) to all stone fruits since it is more effective against Coryneum Blight and bacterial spot than lime-sulphur spray. [Please let me know if you would recommend a different approach based on updated knowledge . . . some of the threads I was reading were three or more yrs. old.]
Question #1: Would the copper + nuFilm17 sticker solution (or copper and dormant oil solution) be effective on the pears against black spot as well??
General Newbie Spray Questions:
Question #2: Does it matter what brand of copper spray I use?
Question #3: Anyone have a small sprayer they love they would recommend? I need to pick one up.
Thank you in advance for your input! I am making my own custom orcharding guide by printing out these threads . . . just read the threads here titled “Dormant Oil Question” on soybean oil usage and “First Time to Use Dormant Oil/Copper.” Trying to do my homework to cut down on newbie questions :).
