Influence of some soil characteristics on the dissipation rate of landrin insecticide


The rates of dissipation of Landrin from nonsterile soils were primarily dependent upon the soil type. The persistence half-lives of the Landrin applied ranged from <4 to >40 days in the 8 soils investigated. Rates of breakdown increased with increasing soil pH (above pH 7), indicating alkaline hydrolysis as the major cause of Landrin degradation; destructive microorganisms were also involved, however. Soil organic matter did not seem to be a major factor in Landrin degradation.
