Dicamba at 28 & 140g ai/ha
Cotton plants were exposed to dicamba at 50% and 10% of a typical field dose rate. The dicamba formulation used was Kamba® 500 (dicamba 500 g a.i./L, present as the dimethylamine salt), a Nufarm product, at 280 ml/ha and 56 ml/ha. Kamba 500 was applied at 6, 11 and 15 nodes of cotton growth, broadcast over the crop in 100 L water/ha. All data were compared to an untreated control.
