OSU Extension Pesticide Properties Database

P.A. Vogue, E.A. Kerle, and J.J. Jenkins. 7/24/94

The OSU Extension pesticide properties database is organized alphabetically by common name. Various trade names are given for each pesticide. Four parameters describing pesticide physical and chemical properties are presented. The database includes pesticides that may not currently be registered for use in Oregon, but may have been used historically or may currently be registered for use in other states. This database relies heavily on the SCS/ARS/CES Pesticide Properties Database for Environmental Decision Making (Wauchope et al., 1992) for the parameter values. The values for the pesticides that were not listed in the SCS/ARS/CES database were either derived by OSU Extension personnel or obtained from Augustijn-Beckers et al. (1994). Please refer to the data source(s) for a complete explanation of the values listed.

The soil half-life is a measure of the persistence of a pesticide in soil. Pesticides can be categorized on the basis of their half-life as non-persistent, degrading to half the original concentration in less than 30 days; moderately persistent, degrading to half the original concentration in 30 to 100 days; or persistent, taking longer than 100 days to degrade to half the original concentration. A "typical soil half-life" value is an approximation and may vary greatly because persistence is sensitive to variations in site, soil, and climate.

The sorption coefficient (Koc) describes the tendency of a pesticide to bind to soil particles. Sorption retards movement, and may also increase persistence because the pesticide is protected from degradation. The higher the Koc, the greater the sorption potential. Koc is derived from laboratory data. Many soil and pesticide factors may influence the actual sorption of a pesticide to soil.

The GUS or Groundwater Ubiquity Score is an empirically derived value that relates pesticide persistence (half-life) and sorption in soil (sorption coefficient, Koc). The GUS may be used to rank pesticides for their potential to move toward groundwater. GUS = log10 (half-life) x [4 - log10 (Koc)].

The pesticide movement rating is derived from the GUS. Movement ratings range from extremely low to very high. Pesticides with a GUS less than 0.1 are considered to have an extremely low potential to move toward groundwater. Values of 1.0-2.0 are low, 2.0-3.0 are moderate, 3.0-4.0 are high, and values greater than 4.0 have a very high potential to move toward groundwater.

Water solubility describes the amount of pesticide that will dissolve in a known amount of water. Most of the values reported were determined at room temperature (20°C or 25°C). The higher the solubility value, the more soluble the pesticide. Highly soluble pesticides are more likely to be removed from the soil by runoff or by moving below the root zone with excess water.
