Screening of Selected Herbicides for Weed Control in Maize Zea Mays L

摘要

An experiment was conducted at Imo State University Teaching and Research farm between April and July 2008 to study the efficacy of selected herbicides in controlling weeds in maize ( Zea mays L. ).The experiment consisted of recommended rates of primextra (T1), Ultrazine (T2) fusillade forte (T3) a weedfree plot (T4) and weedy check (T5) treatments, giving a total of five treatments. The experiment was laid our in a completely randomized design (CRD) in three replicates. Primextra and ultrazine herbicide treatments significantly reduced the mean weed population and increased the vegetative and yield attributes of maize than that of the unweeded plot treatment.
