The 1942-45 introduction of phenoxy herbicides offered selective weed control with limited manpower and resources. Entrepreneurs identified the profit incentive and created a demand for an increasing number of specific weed control chemicals. As a result an imbalanced weed management system was created.

This report summarizes Integrated Weed Management as a primary means of minimizing the use of chemicals and determines methods available for control of noxious weeds. The study included online literature searches and telephone interviews to identify model programs and best practices in other states.
