Farmers' bulletin (United States. Dept. of Agriculture) ; no. 868

"This bulletin tells how to control the Colorado potato beetle and late-blight (the worst two enemies of the potato), blister beetles, flea-beetles, cutworms, and other caterpillars, leaf-hoppers, "aphis" or plant-lice, early-blight, and other foliage diseases. For most of these insects and for the diseases discussed in this bulletin, spraying with Bordeaux mixture and arsenate of lead is recommended, but for leafhoppers and plant-lice, contact sprays, such as nicotine sulphate and eumulsions, are the best. For blight, Bordeaux mixture is an efficient means of control. Directions for preparing and applying these sprays are given. Other methods of control described in this bulletin, such as jarring and driving, together with crop rotation and clean cultural methods, also help considerably in protecting the crop." -- p.
