Effectiveness of 2,4-D and Picloram as Forestry Herbicides

Abstract

Foresters use 2,4-D, alone or in combination with picloram, as often as any herbcide in the South. An active analog of the plant growth hormone indole acetic acid, 2,4-D is used as a In most forest soils in the South where organic matter, moisture, and temperature are adequate, 2,4-D degrades rapidly. Amine and salt tomulations most commonly used in forestry do not change readily. While 2,4-D will leach under some soil conditions, concentrations found in forest streams are infrequently detected at levels approaching the 100 ppb water quality standard.
