Velvetleaf, history and economic impact

, : Velvetleaf, history and economic impact. Proceedings, Southern Weed Science Society, 36th annual meeting: 352

Abutilon theophrasti, introduced into N. America before 1800 as a potential fibre crop, did not develop commercially but has become a serious weed problem in maize, soyabeans, cotton and sorghum in central and S. USA with chemical weed control costing >$500 million/year.
