Abstract

Imopea purpurea (L.) Roth and /. hederacea (L.) Jacq. significantly and equally reduced soybean yields and plant height, and increased lodging and the difficulty of harvesting. Damage to soybeans increased as the population of morningglories increased. Control of morningglories was needed for 6 to 8 weeks from the date of soybean planting. Morningglories germinated throughout the season and emerged from a depth of 6 inches below the soil surface.
