As growers begin to assess fields for burndown options, occasionally weeds get through the program. In addition many growers with wheat are beginning to get out and view potential weed threats. With the specificity of herbicides it is a good management practice to I.D the weeds to ensure a potential resistance and or application error is avoided and or a more effective product is selected in the system. Here is a source for I.D that I think is great this time of year. In fact I just used it today to I.D. some spring weeds. Be sure you have it in your arsenal of books.
