HADSS™ is designed for desktop or laptop computers that use the Windows 95, 98, Me, 2000, XP, or NT operating systems, with a minimum of 30 MB hard disk space, Pentium 90 or faster processor, and a screen resolution of at least 800 x 600.

On the left side of the main screen is a "tree" showing the list of growers and the fields associated with each grower. On the "Field" tab, the user provides information such as the crop, expected selling price, and expected yield.

On the "Weeds" tab, select the weeds for this field and estimated densities. You can choose from an extensive list of weeds available for the crop. The estimated populations are based on a 100 square foot area (for example, 40 ft of 30 inch row, middle to middle).

From the menu at the top of the screen, select "Run" to analyze the data. The first screen to appear after the analysis has completed is the "Damage Estimate" report. This shows the estimated yield loss and money lost, based on the effect of weed competition, estimated weed-free yield, and estimated selling price.

The next screen lists the herbicide treatments, ranked by estimated economic return. Treatments can also be sorted by yield loss remaining, herbicide price, and several other factors.

You can examine treatment details for any of the treatments listed, showing expected weed control, yield loss from the remaining weeds, and cost of the herbicide required for the field area specified.
