Richard, I have used Surround for several years, but only intensely
for one year. Here is my preliminary impressions of it in my backyard
It definitely helps with the curculio. I did not do the best job of
spraying (primarily I started a bit too late on the apples). A few
apple varieties which formed fruits early got hit badly, but all the
other fruits fared pretty well. I am going to need a few more years
to be sure it is working, but my initial impression that I will be OK
using Surround as my only curculio control method -- some fruit were
hit, but after thinning those out I had either a good set or an
overset on nearly all trees.
I find it effective for control of Japanese beetles (and also on
cucumber beetles; not flea beetles however). The Japanese beetles
love my grapes, but the combination of Surround with some hand-control
takes care of them. Before using the Surround it was a whole lot more
work with the hand control.
For control of moths on apples, peaches and plums I have been using a
combination of Surround with spinosad. On some trees this gave
excellent control, on most it was reasonable, and on a few I still had
a good number of worms. I am going to be working on this in the
coming year to see if I can get it to work better.
On the plums I had a problem getting enough coverage since the spray
would bead up; I added a touch of soap and that improved things there
a bit. Coverage was still not nearly as good as on the other fruits.
The peaches had to be scrubbed pretty heavily to get the Surround off.
I also had a big moth problem on my cherries this past year which I
had not treated with anything. I am going to add them to my Surround/
spinosad spray program next year and see if that helps.
