Abstract
Royal Dublin Society, March 26. W. HUGHES: Investigations on the control of seedling disease of sugar beet. A trial was made of the effectiveness against the blackleg disease of sugar beet, of the bulk seed treatment carried out by the Continental producers, in comparison with treatment with various disinfectants in small lots before sowing and with no treatment. A germination test indicated that in the bulk seed treatment some injury was caused by too long contact between seed and disinfectant. In a randomised field experiment, the following materials used before sowing gave a significant increase in establishment of seedlings over the control?Germisan and Ceresan (U.T. 1875 A.), 27-6 per cent, Granosan, 25-6 per cent, and Ceresan (old), 21-7 per cent. The remaining five treatments, which included the seed producers' treatment in bulk, were not significantly better than the control. Seed treatment is recommended as a necessary insurance. E. T. S.
