    Abstract

    A method has been developed to monitor the release of an insecticide from granules into soil. Pesticide release from granules and subsequent movement into the soil is an important parameter in pesticide performance. To date, no quantitative measurements have been made. Past studies have concentrated on either bio-assays or content in the soil solution. Many field efficacy studies have been performed. The described method measures quantitatively release of an insecticide into the soil environment in the laboratory. This method consists of placing pesticide containing granules into a pulverized soil. This mixture is then incubated. Periodically the samples are removed, the clay granules separated from the soil and the soil analyzed for pesticide content. Using this technique the effects of temperature, time, soil moisture, carrier type, etc. are able to be monitored for their effects on pesticide release. The method and some of these effects are discussed.
