The Southern Corn Rootworm and Farm Practices to Control It (open access)

The Southern Corn Rootworm and Farm Practices to Control It

"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.... 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 the 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 rooworm 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." -- p. 2
