Investigations on effect of insecticide-placement techniques at planting for control of greenbug, Schizaphis graminum (Rondani), on grain sorghum, Sorghum bicolor (L.) Moench, were conducted in southwestern Kansas from 1983 to 1985. Granular formulations of terbufos and carbofuran were evaluated as injection, band, or modified in-furrow soil treatments. Terbufos gave excellent season-long control of greenbugs and increased grain yields in 2 out of 3 yr when injected into soil 7.6 cm below and 7.6 cm lateral to the seed furrow. Equivalent rates of terbufos applied in a band on the soil surface gave poor control during the growing season. Granular applications of carbofuran were ineffective in providing season-long control of greenbugs in alkaline soils with a pH of 7.8 regardless of placement method.
