Agricultural Importance

The plant grows very aggressive and can be a noxious weed if left unchecked. This species is easy to identify in the field because of its big purple flowers and large cordate leaves. I. purpurea is an important weed in subtropical areas and strongly interferes with the crop. Tall morningglory is difficult to control.
