Could this product be applied year round? Would applying in the late Fall / early Winter be of benefit to my lawn? How long in between applications should I follow up?
When Quinclorac 75 DF is applied can vary depending on the target weed as directed on the product label. Retreatment intervals can be 14-21 days. Keep in mind that post-emergent herbicides will work best when the target weeds are young and actively growing. Quinclorac is only a post-emergent herbicide, so it doese not prevent any new weeds from germinating.
