Book Description
"The control of the injurious clover leafhopper ... is a comparatively simple task to one acquainted with the habits of the insect. The injuries caused by this insect, as is the case with many other leafhoppers, are often overlooked because of the minute size of the pest, and the apparent injury is too frequently attributed to such causes as soil and climatic conditions" -- Introduction (p.1)

Book Description
"Of all corn pests in the South one of the most serious is the larva, or young of the 12-spotted cucumber beetle -- the so-called southern corn rootworm. True to its name, it feeds on the roots, but in young corn it also drills a small hole in the stem just above the first circle of roots, boring out the crown and killing the bud. Attacked plants either die outright or are so badly stunted as to be unproductive. Lowland corn suffers the most and injury is greatest during cool, damp seasons. The adult, or beetle, is also exceedingly destructive; not, however, to corn, but to cucumber, squash and a great variety of other truck crops and ornamental plants. Progressive farming methods, as described in this bulletin, will reduce the ravages of this insect. Burn over waste places to destroy dead grass, weeds, and rubbish in which the beetles winter, If possible, avoid planting corn in fields which contained corn the year before. Enrich soil by planting legumes so that the corn will have a better chance of recovering from rootworm injury. Protect the bobwhite. This bird destroys many beetles of the rootworm. By careful observations, extending over a period of years, find out the dates between which the rootworm does the most damage; then time your planting so that it will fall either before or after these dates, taking into consideration, of course, other important factors in crop production."--Page [2].
