Abstract
Alachlor [2-chloro-2′,6′-diethyl- N -(methoxymethyl)acetanilide] at 3.4 kg/ha, EPTC ( S -ethyl dipropylthiocarbamate) + R-25788 ( N,N -diallyl-2,2-dichloroacetamide) at 4.5 + 0.4 and 9.0 + 0.8 kg/ha, vernolate ( S -propyl dipropylthiocarbamate) + R-25788 at 4.5 + 0.4 and 9.0 + 0.8 kg/ha, metolachlor [2-chloro N -(2-ethyl-6-methylphenyl)- N -(2-methoxy-1-methylethyl)acetamide] at 1.7 and 3.4 kg/ha, and metolachlor + procyazine {2-[[4-chloro-6-(cyclopropylamino)1,3,5-triazine-2-yl] amino]-2-methylpropanenitrile} at 1.3 + 1.3 kg/ha were preplant incorporated. These herbicides controlled 95% or more of the barnyardgrass [ Echinochloa crus-galli (L.) Beauv.], common lambsquarters ( Chenopodium album L.), redroot pigweed ( Amaranthus retroflexus L.), Powell amaranth ( A. powellii S. Wats.), and yellow foxtail [ Setaria lutescens (Weigel) Hubb.] without injuring sweetcorn ( Zea mays L. ‘Golden Jubilee’) or reducing corn yields or quality. Similar results were obtained with preplant incorporated applications of butylate ( S -ethyldiisobutylthiocarbamate) + R-25788 at 4.5 + 0.2 kg/ha followed by a postemergence application of the amine salt of 2,4-D [(2,4-dichlorophenoxy)acetic acid] at 0.6 kg/ha. Metribuzin [4-amino-6- tert -butyl-3-(methylthio)- as -triazin-5(4 H )-one] at 0.3 and 0.6 kg/ha and metribuzin + alachlor at 0.6 + 2.2 kg/ha applied preplant and incorporated reduced corn stands, primary ear production, and corn yields significantly. None of the herbicides significantly affected total sugars, reducing sugars, soluble solids, moisture content, or succulence of the corn.
