Extract

Several workers have reported that the activity of certain plant-growth regulators is influenced by the particular carrier employed in applying the materials to the plants. The compound 2,4-D is more inhibitory to Kidney bean plants when applied in a Carbowax 1500 aqueous solution than in wholly aqueous solution. The inhibitory effectiveness of oil sprays of 2,4-D is reduced little by rainfall whereas wholly aqueous sprays may be rendered almost noneffective by rainfall a few minutes after treatment. Rice has reported a greater amount of absorption of NH4 2,4-D by leaves when Carbowax 1500 is included in aqueous solutions than occurs when wholly aqueous solutions are employed. The results presented herein are from additional studies on the effects of different carriers and formulations on the inhibitory properties of selected plant growth-regulators.
