Take time to prevent spreading headaches from field to field. If you had fields (or part of fields) that you struggled with weed control this year, do not compound the problem by spreading seeds. The key culprits are Palmer amaranth and herbicide-resistant common ragweed. Harvest the weedy sections of the fields last. Clean your equipment before you leave the field, so you are not spreading the seeds as you travel down the road. Combines, stalk choppers and mowers are all very efficient at spreading weed seeds.
