The original formulation of Surround had a separate adjuvant to mix with the spray but the newer ones have the adjuvant (my guess is that it's linseed oil) mixed in with the clay. Do you think that the X-70 still improves performance?

I have used Surround on my apples for about five years now, using a Stihl backpack airblast sprayer. Results have been very poor. I do still get curculio damage and my crops are very, very low. I spray right after petal fall once a week or so then move up to 2 week intervals unless there's an inch of rain, in which case I reapply. I usually mix elemental sulfur in with the spray. I'm not sure exactly why my crop is so poor but when I used to used two sprays of Imidan followed by maggot traps I always got good yields.

Any suggestions/insights appreciated.

Also, I have found that adding 3 oz/100 of X-70, an approved adjuvant,
helps Surround cover the trees well.  This is especially true if lime
sulfur is added to the spray, which I find makes Surround slide right off
the leaves.

Best wishes,

Dear Brian,
I am not familiar with X-70 and find nothing in search.  I'll do most
anything to improve my Surround coverage.  I do hand to hand
combat with plum curculio yearly.

is it a spreader/sticker??
