Data from usable pesticide survey responses was entered in a computer database and checked for entry errors. A database record was stored for each unique combination of grower, crop, pesticide, and target pest(s). All character data (such as brand names) were standardized for consistent usage and spelling. Specific methods used to enter and standardize data and to perform calculations are described below:
