The quick and easy pre-harvest interval tool — the spray-to-swath calculator — helps you find a fungicide, insecticide or pre-harvest herbicide that fits your timeframe available.

If a crop will be ready to swath within three weeks, for example, and diamondback moth larvae are above thresholds, then the grower needs a product with a pre-harvest interval of 21 days or less. With the calculator, the user can select the estimated number of days until swathing or straight combining, and the tool provides all the products available to use within that window.
