Estimating outdoor use of pesticides in urban settings requires the consideration of factors that are not typically addressed in agricultural settings. Urban/residential pesticides are used in home gardens, landscape aesthetics, vector control, preservation of wooden structures, and otherwise to erradicate or deter pests in residential and urban premises. California is unique relative to other states in reporting requirements for pesticide applications. Howver, urban use records are not as precise as agricultural records that report the day of application and at a PublicLand Survey System (PLSS) spatial resolution. Urban applications are reported only by licensed Pest Corol Operators at much coarser monthly and county-level resolutions. Homeowner use is not contained in the PUR. A method for estimating non-agricultural outdoor applications of pesticides by professional and homewoners at a daily and PLSS resolution was developed using the county-level PUR database, homeowner sales data, land use records, statistics derived from surveys, and other availabile sources. The results have been used to predict potential pesticide runoff from urban and residential areas.
