Corn harvest in South Carolina typically begins in August. The weeds remaining after harvest can contribute to future infestations. This is because we have several months of good growing conditions for weeds after harvest. For example, Palmer amaranth, sicklepod, and annual morningglory can continue to grow and produce seed. Palmer amaranth is capable of producing enormous amounts of seed during after harvest but before the first killing frost. Here are some post-harvest herbicide options for management of these weeds after harvest which reduces the potential for adding more weed seed to the soil seed bank.
