Plan now for weed management in row crops to prevent Palmer pigweed infestations like this one!

Now is the time of year growers should plan their weed control programs.  Palmer pigweed management requires using the right herbicides in a timely manner. Below are the UF/IFAS recommended Palmer pigweed management programs for cotton and peanuts.

If you would like more information about weed control, contact your local UF/IFAS Extension Agriculture Agent or see the fact sheet called Control of Palmer Amaranth in Agronomic Crops.
