Abstract
Field experiments were conducted in 1983 and 1984 to compare the influence of six different minimum-tillage treatments on the overwintering emergence of Ostrinia nubilalis (Hübner) in cornfields. The treatments were: unharvested control, harvested-only, mowed, disked, disked-bedded, and mowed–disked. All treatments reduced O. nubilalis survival compared with the unharvested control. O. nubilalis survival was least during both years in plots that were both mowed and disked. O. nubilalis emergence was significantly earlier in the mowed–disked treatment compared with the harvested-only treatment. The duration of emergence per treatment was longest in the unharvested control and harvestedonly treatments compared with other treatments.Keywords
