We give demonstrations
in the use of both liquid and dust sprays to overcome fungoid diseases in potatoes, of which there are about half a dozen, and among other pests we encounter the potato bug. The treatment costs about a dollar or a little more per acre, including labour and material. What is known as the potato spraying machine is used; it covers several rows at a time. This particular pest cannot be controlled, so far as I know, by any treatment of the soil, but the other remedies I have mentioned, while not costly, are, I think, highly efficient.
