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 the Central States, it would be an
advantage for all of us.
MR. STOKE: In my area the control of the pest is complicated by the presence of the chinquapin.
PRESIDENT BEST: We have a surprise feature this afternoon. Dr. Graves of the Connecticut Experiment station, who, as you know, is the father of a lot of this work on chestnuts, has consented to discuss with us certain new procedures that he used in grafting chestnuts.
