Field experiments were conducted in 1992 to 1993 and in 1995 to 1996 in Ibadan, Nigeria, to assess the effect of velvetbean and herbicides on maize (corn) and cogongrass growth and to assess regrowth of the weed 1 yr after treatment. In 1992 and 1995 cover cropping with velvetbean and imazapyr an...

Speargrass, Imperata cylindrica (L.) Raeuschel, is a serious weed, threatening crop productivity in smallholder farms in West Africa. Since the use of more effective practices such as deep tillage and chemical control is beyond the means of resource-poor farmers who carry out most agricultural ac...

Evaluation of Lumax for preemergence weed control in maize in Nigeria
The effects of a new formulation of atrazine for weed control in maize were studied during the wet season of 2002 and 2003 at Ibadan, Nigeria. The treatments were the new formulation at doses from 1.0 to 3.5 kg a.i./ha and the old formulation at the recommended dose of 3.0 kg a.i./ha. Untreated a...
