Results of a two year study that compared insect populations and yields in cotton with narrow (30") or normal row (40") spacings showed in both years an increase in bollworm, Helicoverpa zea (Boddie), and tobacco budworm, Heliothis virescens (F.), damage in cotton planted in narrow rows. Control of early season pests with temik produced higher yields in cotton with both row spacings each year, as compared to yields in cotton in which cygon was used for early season pest control.
