What is WeedCast?

WeedCast is an easy to use software program that forecasts three types of weed growth: Emergence Potential, Emergence Timing, and Seedling Height. The forcasted data provides valuable information that can be used to aid in making weed management decisions. WeedCast is designed to function with a minimal amount of input.

Resulting data is displayed in a spreadsheet form and may be graphed from within the program.

What is WheatScout?

WheatScout is a decision aid that predicts the effects of a variety of herbicides on green foxtail and wild oat in wheat crops. It requires similar information to Weedcast, but also requires some scouting information.
