Combination Glyphosate plus 24-D 
Herbicide Damage Information

2,4-D plus glyphosate in combination at 35 plus 8g ai/ha   and   173 plus 80g ai/ha

Cotton plants were exposed to a combination of glyphosate and 2,4-D amine. The glyphosate was applied at 17% and 3% of the field dose rate commonly used in cotton, and the 2,4-D was applied at 10% and 1% of a typical field dose rate. The glyphosate formulation used was Roundup Ready Herbicide® (glyphosate 690 g a.i./kg, present as the mono-ammonium salt), a Nufarm product, at 250 g/ha and 50 g/ha. The 2,4-D formulation used was Baton® (2,4-D amine 800 g a.i./kg, present as the dimethylamine salt), a Nufarm product, at 100 g/ha and 10 g/ha. The combinations were applied at 6, 8, 12 and 16 nodes of cotton growth, broadcast over the crop in 100 L water/ha. All data were compared to an untreated control.
