Wetting Ability of Aqueous Herbicidal Sprays as a Factor Influencing Stands of Alfalfa Seedlings1

  1. K. P. Dorschner and
  2. K. P. Buchholtz2



Wetting ability of an herbicidal solution was found to be a significant factor in determining the toxicity of preparations and rates of any one compound, but was of minor importance in explaining differences in toxicity between chemicals. 2,4-D was the most toxic, followed by 2,4,5-T, MCP, 3,4-D, and 2,5-D in that descending order. Artificial shading indicated that light available to alfalfa seedings in oats- was important in maintaining alfalfa stand. Shading increased the wettability of alfalfa leaves and presumably increased the toxicity of herbicides applied.
