A review of the effects of long-term 2,4-D and MCPA applications on wheat production and selected biochemical properties of a Black Chernozem

Abstract

Rotational plots at an experimental farm at Indian Head, Saskatchewan, have been receiving annual applications of amine and ester formulations of 2,4-D since 1947, and MCPA amine since 1953. It is concluded that there have been no adverse effects on crop productivity of the soil from the long-term use of 2,4-D and MCPA. -from Authors
