Weeds are the bane of many farm operations, and consequently, farmers spend more money on herbicides than any other production input other than fertilizer. However, it can be difficult to choose what herbicide or herbicides to use. There are many herbicides to choose from, each with their own strengths and weaknesses. Additionally, there is a myriad of weed species competing with wheat for water, light, and soil nutrients. Although the Winter Wheat Herbicide Efficacy Tables will not tell wheat growers what herbicide or herbicides to use, it will help growers narrow their herbicide options based on the weeds that they are most concerned with.
In addition to the Winter Wheat Herbicide Efficacy Tables, The Herbicide Mechanism of Action (MOA) tool was recently released. Both of these tools were designed to harness the research generated at WSU and elsewhere to help growers make more informed decisions for their farm operations. Development of these tools was partially supported by funds from the Washington Grain Commission. Feedback on either of these tools is welcome!
