Furthermore, emergence of any species never occurs instantaneously as a sudden single flush. Instead, emergence occurs over an extended time span, and the rate of emergence may vary greatly (i.e., flushes) during this time. Because emergence is the single most critical phenological event for weed control, this variability in emergence has great impact and importance for weed management. Accordingly, understanding and predicting emergence has the potential to greatly enhance our ability to manage weeds successfully. The user-friendly software, WeedCast, was developed to provide quick and easy forecasts of basic weed phenology for crop consultants and producers, in addition to extension specialists, educators, and researchers. Such software facilitates the implementation of fmanagement strategies on a more biological basis, which makes weed control less risky, more profitable, and perhaps more acceptable to a skeptical public. |
