EVALUATION OF BAND VS BROADCAST HERBICIDE APPLICATIONS IN CORN AND SOYBEAN

Weed control in corn (Zea mays) and soybean [Glycine max (L.) Merr.] w ith band applications of herbicides plus cultivation was evaluated in these studies. Giant foxtail (Setaria faberi Herrm.) and velvetleaf (A butilon theophrasti Medik) control in corn with band applications plus cultivation was equal to or better than control with broadcast applic ations without cultivation of the same herbicides 2 of the 3 yr. Ivyle af morningglory [Ipomoea hederacea (L.) Jacq.] control was less consis tent with band applications plus cultivation than with the broadcast a pplications. There was no difference in yellow nutsedge (Cyperus escul entus L.) control between the band applications plus cultivation and b roadcast applications averaged over years. Giant foxtail, velvetleaf, ivyleaf morningglory, common cocklebur (Xanthium strumarium L.) and ye llow nutsedge control in soybean with band application plus cultivatio n was equal to or better than the control with the broadcast applicati on 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 cultivation s than with the broadcast application of the same herbicides. Band app lication plus cultivation reduced the total amount of herbicide applie d per acre by 66%.
