Physical Aspects of Soil in Relation to the Action of Soil Fungicides

Abstract

The action of a fungicide in soil is predictable if certain physical, chemical, biochemical, and toxicity parameters are known. These include vapor pressure, water solubility, distribution between soil organic matter and water, range of degradation constants in soil, and doses required to control various organisms. Predictions can be made qualitatively without the need for mathematical analysis, or quantitatively by mathematical analysis of the entire system involved.
