It's a Good Time to Think About Controlling Perennial Weed Species
Perennial weed species often become established in no-till production fields and can sometimes cause a great deal of frustration regarding how best to control or eradicate them. Without the option of mechanical control (in other words, tillage), perennial weed species are generally best controlled by postemergence translocated herbicides. Selection of which translocated herbicide to use as well as when to make the application can impact the level of success achieved.

Regional Reports
Extension center educators, unit educators, and unit assistants in northern, west-central, east-central, and southern Illinois prepare regional reports to provide more localized insight into pest situations and crop conditions in Illinois. The reports will keep you up to date on situations in field and forage crops as they develop throughout the season.

This week's issue includes reports from northern Illinois and west-central Illinois.
