WebFactors Impacting Rates of Pesticide Breakdown • Soil pH influence the rate of pesticide breakdown due to reaction with water – pH of soils east of the Cascades ranges from about 5.4 (Union county) to 9.6 (neutral to basic) • Dissolved organic matter and metal ions • Temperature • Tough to generalize- all chemicals are different, like ... Webof pH on pesticide activity. The pH scale is a measurement of the acidity or alkalinity of a substance and ranges from 1 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is alkaline. The scale is logarithmic, which means pesticide sensitivity to water pH increases by a factor of 10 for each pH unit. For example, a
