Expert addresses spring lawn weeds

The Jefferson County Cooperative Extension Service is receiving a lot of calls about weed control in Jefferson County lawns this spring now that the green up has happened, Dennis Bailey, Extension service agent-staff chair, said.

“This is about a month later than last year but the available information has not changed. If you missed the window for a pre-emerge product that kills the weeds before they become visible, you must look for a post-emerge or over-the-top product that is best for the wide range of weed species out there,” Bailey said.

First, think about proper fertilization and getting soil testing done in order for the desirable lawn grass to defend its self. Next, obtain a proper ID on the weeds to make sure the right product is purchased. “Grassy” weeds and “broadleaf” weeds usually will require two different products and there are many available which leads to confusion.

Residents also must be aware of the lawn grass they are maintaining. St. Augustine and Centipede grass varieties are sensitive to many products with 2,4-D while Bermuda and Zoysiagrass will tolerate most any broadleaf weed product. Products containing a three-way combination of 2,4-D, Meccoprop and Dicamba are always best for the tougher weeds that have some growth already. Some of these mixtures are formulated for the ‘southern’ grasses and less damage will occur at labeled rates.

Bring your weed samples and questions to the U of A Extension Staff at 500 Idaho Pine Bluff or call 534-1033 for more information. Always read the entire label on any product before application.
