I only have about twenty trees and am surrounded by woods. I believe that the curculios come in from the woods, where they overwinter, so applying nematodes here would do no good on that generation. Perhaps Neem would do something, but I consider it pretty much of a regular pesticide (vs. a physical deterrent, like Surround). Neem is a feeding deterrent and insect growth regulator so may have no effect on curculio because the damage comes from the adult female laying an egg inside the fruit,

Lee,

Have you tried the nematodes? I'm not convinced that they make a huge dent,
but I have had success using shotgun approaches to difficult pests: many
things that work a little working synergistically... Neem, Surround,
Nematodes, and traps, for instance.

I'll put in my two cents on Surround: I've used it for about three
years, applying it with a Stihl backpack sprayer. My yields have been
very low, despite the fact that I get very good coverage and apply it
frequently. A couple of years ago I thought maybe I was applying it
too frequently or that the force of the blower was knocking off the
fruit.

This year, so far, I've started out with once a week spraying right
after petal fall, mixing sulfur in to control scab. There's still
many fruitlets on the trees, but many -- my offhand guess is 80
percent -- are showing curculio damage. Any insights? I'm hoping not
to go back to spraying imidan.

By the way, I'm in Zone 5 in New York's Hudson Valley.

Also, as common sense, do not assume that the fineness of Surround
is not present
in a bulk product of Kaolin. Englehard is not selling enough of
this stuff to
create a whole new grade of milling. Kaolin is used in tons of
cosmetics and
other really super fine usages. The correct mill grade for the home
sprayer is
definitely out there. I am going to look on some bags of Surround
tomorrow and
see if it reveals the mill grade. I see three possible sellers, one
in Tennessee
and another from an own-line dealer. We'll see. Anyone else got
some time to help
look into this?
