Bonehead said:Many years ago I worked for the College of Forestry at the Univ. of Wash. Monsanto funded a study of 2,4-D for use as weed control for replanted evergreens following clear-cutting. They soaked circles of cardboard in the chemical and placed those around the seedlings. The control group was cardboard with no chemical. As it turned out, there was no significant difference between the two control groups.
