NW Washington | The longer you can wait between the burn down and seeding the better off things will be for the wheat, due to better control of the so called "green bridge" effect of diseases going grass hosts to the seeded wheat. And as mentioned one burn-down is not going to get all of grassy weeds like quack grass. But for 5 acres it should not too bad. Here is some info on the "green bridge" effect that was first figured out by James Cook at Washington State U/USDA ARS.
"Northwest research has shown that volunteer grain and weeds growing between crop harvest and spring planting under no-till and minimum tillage can serve as a "green bridge" host for build up of some root diseases caused by soilborne pathogens. But early control of this green bridge -- beginning in the fall when possible -- has proven to be an effective management tool for minimizing losses from some root diseases, such as Rhizoctonia root rot, Pythium root rot and take-all. In addition, fall control can also reduce the incidence of Cephalosporium stripe, improve control of winter annual grassy weeds, such as downy brome and jointed goatgrass, and reduce populations of Hessian fly. A video and two PNW Extension publications provide more information on early green bridge control as an effective pest management tool to enhance crop yields under conservation tillage systems."
