A weed extension specialist says control efforts have been hindered by dry conditions.
Michigan State University’s Christy Sprague tells Brownfield soil-applied herbicides need moisture to activate and that’s been in short supply.
“A lot of those soil-applied products really did not get moved into the soil and are not showing a lot of good performance,” she shares.
Sprague says weeds have also stopped actively growing which has created some limitations in post-emergence products.
