Competition and seed-rain dynamics of velvetleaf in cotton

Velvetleaf (Abutilon theophrasti) is a member of the family Malvaceae that has proven to be an intense competitor in several agronomic crops. Much research has been conducted on the interference characteristics of velvetleaf in corn and soybeans while little has been conducted with velvetleaf in cotton. Competitive characteristics of velvetleaf include factors such as seed dormancy, ability to germinate from deep within the soil, prolific seed production, and limited control measures. Past research has reported yield reductions of 2.7% per velvetleaf plant in 33 ft. of row. Yield and harvesting efficiency reductions can be attributed to velvetleaf in cotton as well as a number of other economically important crops. Seed production of economic and sub-economic threshold populations is a concern and there is no published data on this area.
