Crop producers pay less attention to combating weed problems during the fall and early winter months. However, this is an optimum time to critically evaluate successes and failures of the past season and make plans for the upcoming growing season.
It is a good time of year to consider what weed control strategies worked and what options did not perform up to expectations during the growing season, and why. Where control practices failed, you may want to consider what weed problems or escapes occurred in the field, if these weed species are annuals or perennials, and whether they are reoccurring problems. Also consider whether weed control practices would have been effective on target weed problems and if environmental conditions before, during or after the treatment had any impact on effectiveness.
Even if control was acceptable, it may be advisable to evaluate costs compared to the benefits, because other more cost-effective options may be available. Evaluating costs is a major consideration as you plan for the next crop season.
