I am sorry to say I don't have any information on these newer materials, like DDT, methoxychlor and parathion. You have probably read about all of those in the magazines. Some of the men in our department have done quite a bit of work with these insecticides on the apple maggot in the Hudson Valley and in Western New York and they find, as I mentioned earlier, while it's possible to obtain control of apple maggot, say, with DDT, it requires much more frequent application. In that case, if any of you are orchardists or follow the apple-growing insect problems at all, the first application of the walnut maggot spray should go on at about the time the last cover spray for the coddling moth goes on for the first brood. That sounds a little involved, but from the calendar point of view it would be about July 25th in Central or Western New York. Normally, with us here the cherries are being harvested by about July 15th, sometimes a little earlier, but at any rate, that's the time the flies usually begin to emerge. We have what we call a pre-oviposition period of about two weeks, during which time the flies are not laying any eggs in the shucks and are moving around feeding. Of course, that is the time you have to get this spray material on, before they have punctured the nuts and deposited eggs inside. I think, unless there are questions, that's all I have to say. A MEMBER: You recommend No. 3 to be used? DR. GAMBRELL: Lead arsenate at 3 lbs./100 gallons and 2 gal. of lime sulphur would be an effective insecticide-fungicide mixture. I have used both the wettable sulphur and lime sulphur, as shown here, without any injury to foliage. Sometimes, as you know, if it's real hot, like today, sulphur could cause you a lot of foliage injury. Dr. MacDaniels will certainly bear me out on that. PRESIDENT BEST: Now I think Joe McDaniel has a little idea here he wants to introduce at this time. DR. MACDANIEL: I have been talking with Mr. Devitt. He is interested in following up these Carpathian trees in Ontario and is willing to act as our agent in securing seed nuts from some of the better selected trees. As I understand it, this Association couldn't properly act as a sales agency for them, but I believe there are some of the members who would like to get these superior seed nuts of Ontario, and I would be willing to take the names of persons who are interested in them, either for their personal planting or for resale. Mr. Devitt thinks he can secure the nuts at about 60 cents a pound from the owners who have these good trees and deliver them to the United States at around a dollar a pound. Anyone who is interested in that, see me or Spencer Chase during the remainder of the meeting. Panel Discussion: The Persian Walnut Situation _Moderator_: S. B. CHASE; _Panel Members_: H. L.
