Abstract Insecticides were evaluated at 3 sites in western Virginia (Augusta, Wythe, and Montgomery Counties) for control of larvae of NCR and WCR. Four tests were conducted. Insecticides were applied at planting. In 2 of the 4 tests the investigators applied the insecticides to the surface of the ground directly over the furrow in a 6-inch-wide band with a hand-pushed granular spreader. In the other 2 tests the farmers applied the insecticides in furrow, along with the corn, at planting. In all cases, only 1 application of insecticide was made/row. All plots were established in a randomized complete block design with 4 replicates. Each plot was 4 rows wide and 50 ft long. In the banded tests, the replicates were arranged parallel to one another; in the in-furrow tests they were arranged linearly. All samples were taken from the center 30 ft of the center 2 rows of each plot. The corn plants were counted about 2 wk after planting. In mid-summer, damage from larvae was assessed. The lodged plants, those that had toppled because of root system damage by larvae, were counted about 2 months after planting. Actual damage to corn roots also was estimated. This damage was rated on a scale of 1 to 6 (1, damage; 6, complete destruction of the root wad). Root wads of 10 plants/plot were prepared for inspection by the following method. One person stood at either end of each of the 2 center rows, walked about 10 ft toward the center and then unearthed the root wad of every other plant until each had 5 root wads. The roots were then thoroughly washed with hot water from a pressurized sprayer. Ensilage yields were determined at harvest by cutting stalks and weighing them using a sling swung from milk scales attached to a portable tripod. Plant stand counts, lodging counts, damage ratings, and yields were subjected to ANOVA. Two of the 4 tests (one banded and one in furrow) were in Augusta County. In both tests, ‘Doebler X-67’ field corn was planted no-till in rows 36 inches wide on 16 May, and plants were counted 2 Jun. For the in-furrow test, lodged plants were counted on 13 Jul, root damage was rated 13-14 Jul, and yields were determined 6 Sep. In the banded test, the insecticides were applied 3 d after planting, on 19 May. Lodged plants were counted 18 Jul, root damage was rated 18-20 Jul, and yields were determined 15-19 Sep. In the Wythe County test, which was in furrow, ‘Southern States 950’ field corn was planted no-till in rows 34 inches wide on 9 May. Plants were counted 31 May, lodged plants were counted 25 Jul, root damage was rated 25-26 Jul, and yields were determined on 12 Sep. In Montgomery County, ‘Penny’s SX-112’ field corn was planted no-till in rows 30 inches wide on 20-21 May, and insecticides were applied as a band on 24 May. Plants were counted 17 Jun, lodged plants were counted 1 Aug, root damage was rated 1-4 Aug, and yields were determined 21-22 Sep. All fields previously had a cover crop of rye.
