The introduction of 2,4-D-resistant crops stacked with glyphosate resistance will enable the use of 2,4-D and glyphosate for weed control in corn, cotton, and soybean. Because there is little reported on the effectiveness of 2,4-D plus glyphosate on summer annual weed control, the objective was to evaluate 2,4-D and glyphosate tank mixtures on summer annual weed control. Six rates of 2,4-D (0, 280, 420, 560, 840, and 1,120 g ae ha−1) and three rates of glyphosate (0, 840, and 1,120 g ae ha−1) were applied to common lambsquarters, common waterhemp, giant ragweed, giant foxtail, and velvetleaf. Glyphosate at 840 g ha−1 controlled all weeds 94 to 100%. Giant ragweed was controlled 99 to 100% by 2,4-D alone when rates were 280 g ha−1 or higher. Common lambsquarters, common waterhemp, and velvetleaf control increased as 2,4-D rates increased, with 1,120 g ha−1 providing 90 to 94% control.

La introducción de cultivos con resistencia a 2,4-D en combinación con resistencia a glyphosate hará posible el uso de 2,4-D y glyphosate para el control de malezas en maíz, algodón y soya. Debido a que hay pocos reportes sobre la efectividad de 2,4-D más glyphosate en el control de malezas anuales de verano, el objetivo fue evaluar mezclas en tanque de 2,4-D y glyphosate en el control de estas malezas. Seis dosis de 2,4-D (0, 280, 420, 560, 840 y 1120 g ae ha−1) y tres dosis de glyphosate (0, 840 y 1120 g ae ha−1) fueron aplicadas a Chenopodium album, Amaranthus rudis, Ambrosia trifida, Setaria faberi y Abutilon theophrasti. Glyphosate a 840 g ha−1 controló todas las malezas de 94 a 100%. A. trifida fue controlada 99 a 100% con 2,4-D solamente cuando las dosis fueron 280 g ha−1 o mayores. El control de C. album, A. rudis y A. theophrasti aumentó al incrementarse las dosis de 2,4-D, con 1120 g ha−1 brindando 90 a 94% de control.
