Effect of pre-plant herbicides on weed control and performance of okra Abelmoschus esculentus in a south western nigerian location Ademiluyi, Oluwafemi Benson, Arowosegbe S. Department of Plant Science, University of Ado Ekiti, Nigeria Online published on 22 February, 2013. Abstract Field trials were carried out over two years to evaluate the performance of Okra Abelmuschus esculentus and weed control efficacy using pre-plant herbicides. The treatments were weedy check, pre-plant glyphosate, pre-plant pendimethalin at three different applications of 10, 7, and 3days before planting, and hoe weeding. Pendimethalin applied pre-plant either at 3, 7 or 10DBP at the rate of 1.0kg active ingredient ha −1 and hoe weeding twice at 3 and 5weeks after planting produced better weed biomass reduction, plant height, and pod yield when compared with the pre-plant glyphosate application and the weedy check control. Pre-plant pendimethalin at 3DP gave slight reduction in emergence and subsequent establishment counts.
