[Footnote 14: —Goldsworthy and his associates published several items along this line in 1948 issues of +Plant Disease Reporter+. His October 15, 1948 item reported a similar result of 25% technical DDT (with 75% clay) inhibiting growth of seedling peach roots on 1-year budded Elberta trees. As low as 25 pound per acre application affected growth in quartz sand cultures, whereas with certain soils, no significant difference was noted until an 800 lb. per acre level of the DDT was reached. It was surmised that possibly some unknown constituent in the technical DDT was responsible for the suppression of new root growth, and consequent slowing down of top growth. In the case of Blakemore strawberries, and also with peaches, this effect has persisted for at least two crop years. Goldsworthy and Dunegan say, "How many other economic crop plants may be injured is unknown, but it appears certain that some caution is necessary in the promiscuous use of the chemical on … plants, either as … sprays or as soil additions…." In these experiments, of course, the DDT-containing material was in direct contact with all the roots. Spray residues ordinarily would be present only in the surface layer of the soil, and should have much less effect on tree roots in that case.—J. C. McDaniel.]

+Evening Session+
President Davidson: The meeting will come to order, please. We first have the pleasure of hearing from Dr. C. A. Moss of Williamsburg, Kentucky, on Greetings from a Kentucky Nut. Dr. Moss.
Greetings from a Kentucky Nut
DR. C. A. MOSS, Williamsburg, Kentucky
I am glad to see all of these beautiful ladies here this evening. We just had dinner, and I presume I should make an after-dinner speech. I have always wanted to attend a Northern Nut Growers Association convention. I am more or less of what you might call a convention addict and speak on any occasion on slight provocation. I attended a convention at Quebec earlier this year, and after that I went on to Rio de Janiero in South America and attended another convention, but this privilege of being able to attend the Northern Nut Growers Association tops all the rest.
