Evaluation of Band vs. Broadcast Herbicide Applications in Corn and Soybean

摘要

Weed control in corn (Zea mays) and soybean [Glycine max (L.) Merr.] with band applications of herbicides plus cultivation was evaluated in these studies. Giant foxtail (Setaria faberi Herrm.) and velvetleaf (Abutilon theophrasti Medik) control in corn with band applications plus cultivation was equal to or better than control with broadcast applications without cultivation of the same herbicides 2 of the 3 yr. Ivyleaf morningglory [Ipomoea hederacea (L.) Jacq.] control was less consistent with bandapplications plus cultivation than with the broadcast applications. There was no difference in yellow nutsedge (Cyperus esculentus L.) control between the band applications plus cultivation and broadcast applications averaged over years. Giant foxtail, velvetleaf, ivyleaf morningglory, common cocklebur (Xanthium strumarium L.), and yellow nutsedge control in soybean with band application plus cultivation was equal to or better than the control with the broadcast application of the same herbicides without cultivation. Corn and soybean yields were related to the level of weed control. Weed control costs in corn and soybean were lower with the band application plus two cultivations than with the broadcast application of the same herbicides. Band application plus cultivation reduced the total amount of herbicide applied per acre by 66%.
