Herbicide resistant stewardship in rice (poster)
This poster describes weed resistance, the factors affecting the evolution of resistance, and how to delay the evolution of resistance.

Weed Control Programs, 2006 Rice Production Workshop
The discussion and tables in this chapter provide a framework for decision-making in rice weed control.

Weed susceptibility chart
The herbicide ratings used in this chart are averages for the performance of the herbicides in the state when the herbicide is applied at labeled rates for crop production.

Managing Herbicide Resistance Using Alternative Rice Stand Establishment Techniques
Widespread herbicide resistance in the major weeds of rice is a serious threat to the sustainability of rice production in California. Integrating cultural and chemical weed control practices may decrease weed management costs, delay the evolution of herbicide resistance, and reduce weed seed banks.
