Abstract
The rate of inactivation of 2,4-dichlorophenoxyacetic acid in soil varied according to the moisture content of the soil during storage; the highest level used (30%) resulted in most rapid inactivation. Inactivation of 2,4-D in soil also increased with the, temp. at which the mixtures were stored, the most rapid inactivation occurring at 70[degree]F, the highest temp. used. Applications of 2,4-D that were mixed into the soil were inactivated during a shorter period of time than were like amts. applied to the soil surface. Light applications of manure to soil low in organic matter materially hastened the inactivation of 2,4-D. The inactivation of 2,4-D in soil was significantly reduced by autoclaving.Keywords
