Excerpt from Experiments for the Control of the Grape Root-Worm On the basis of the experiments described, two methods of con trol are recommended: (i) Molasses, 2 gallons, arsenate of lead, 6 pounds, and water 100 gallons, followed in about one week with an application of bordeaux mixture (8 - 8-ioo) and arsenate of lead 6 pounds; (2) two applications of bordeaux mixture (8-8 - Ioo) and arsenate of lead, 6 pounds at an interval of about ten days. The first system of treatment is especially recommended when the beetles are present in excessive numbers, but the second is advised for general vineyard spraying when beetles are not abundant.
