Mid- To Late-Season Options:What's available for weed control after early season herbicides dissipate?

摘要

Preplant and preemergence herbicides have likely done what they can, and new weed flushes are starting to emerge. Herbicides applied early postemergence that do not have soil activity may give way to new weed flushes as well. In other words, good early season weed control may need some attention because previously applied herbicides have dissipated over time. So what options do we have at this time of year?
