In most forest soils in the South where organic

moisture, and temperature are adequate,

rades rapidly. Amine and salt

ons most commonly used in forestry do

not change readily. While 2,4-D will leach under

some soil conditions, concentrations found in

s only slightly toxic to

62-y low in toxicity to

oaccumulate and is

r removal of undesirr the right conditions. Some nontarget

plants can be affected by low concentrations in

water.

The effectiveness of 2,4-D and picloram in

controlling important forest weeds has been

documented by a number of studies. The more

important ones are listed in this fact sheet.
