Abstract:
... Fifty-nine sweetpotato cultivars, including 16 heirlooms, 11 near-heirlooms (developed in the 1960s and 1970s), 19 cultivars from the 1980s, and 13 modern varieties (since 1990), were evaluated for resistance to soil insects in field experiments during 2010–2011 at the U.S. Department of Agriculture-Agriculture Research Service, U.S. Vegetable Laboratory (USDA-ARS, USVL), Charleston, SC.

Abstract:
... In 1990 and 1991, the efficacy of reduced application rates of soil insecticides registered for corn rootworms, Diabrotica spp., and the prevalence of economic injury caused by these key pests were determined in the fields of growers in northern Illinois. Fifty-eight experiments were conducted in 10 Illinois counties during this 2-yr period. Root injury ratings from these on-farm experiments indic ...
