flowing and can be applied quite readily with any
fertilizer or distributor.
Without any field experience to go by it would seem that a 5% 30-60 mesh
DIELDRIN granule formulation would be most convenient to use. By using a
5% DIELDRIN granule material you would obtain a dosage of 1-1/2 pound of
actual DIELDRIN per acre by applying 30 pounds of granules per acre.
Likewise, 60 pounds of the granules per acre would give a dosage of 3
pound of DIELDRIN. On the basis of work done with DIELDRIN for the
control of the Japanese beetle, 3 pounds of DIELDRIN per acre will
control this insect for more than 5 years. While it is not safe to
assume that we could expect the same results in the case of the Hickory
weevil, it does give us something to go by."
It seems likely that the foregoing will create some interest and that by
the time of the next annual meeting we should have the results from the
use of DIELDRIN to control the Hickory weevil.
MR. PAPE: It is my thought now if we could get a little discussion here
concerning what some of you have been doing to control this pest, we
might get somewhere, or at least get enough suggestions or get enough
parties interested to carry on some experiments in different parts of
the country.
MR. SILVIS: What company makes Dieldrin?
MR. PAPE: Julius Hyman Company is the one that sent the most literature
and Shell Corporation local agents handle it. Also in Indiana the Farm
Bureau Cooperative store handles it. The cost in small quantities is two
pounds for 85 cents.
MR. KYHL: Is Dieldrin poison?
MR. PAPE: It's poison like all of these modern sprays, but it isn't as
dangerous as Parathion.
MR. STOKE: In Virginia I have had no experience with DDT, except with
chestnut, and it takes three sprays at two-week intervals to control the
pest.
DR. GRAVES: What time of the year?
MR. STOKE: Apply the last spray about two weeks before the nuts ripen.
That means, with us, starting in late July. You have to figure it for
your own region.
MR. GRAVATT: There is literature available from the Bureau of Entomology
in Washington on spraying to control pecan and chestnut weevils. They
have done quite a bit of research on it.
MR. STOKE: If this ground treatment is effective, I'd like to try it.
It's a lot easier.
MR. PAPE: That would be very nice if you would repeat the work in
Virginia. I know that the Pecan Growers will work on the problem in the
South. If we could get work done in t
