After Go> is clicked for Weed Layer (Select Layers screen), a dialog box is displayed for entering the name of the field that stores the weed names in the Weed Layer:
After this name is supplied, the Weed: Treatments, Weeds, and Application Method Data form (shown below) is displayed. On this data entry form you will identify, for each invasive species, a chemical treatment to be analyzed, its application rate per acre, how much of which surfactant, and the cost per acre for the chemical (we will add the application method cost later). This form contains four tabs: Treatments data, Weed rank and spread rates, Application methods data, Treatment/Method.
The application method selection and data entry are made on the top portion of the screen, then the Add>> button is used to enter a data row in the table in the lower portion of the screen.
