SCA have been confirmed at 5 different sites around Hillsboro, TX on Johnsongrass. Sites are checked weekly and so far no winged aphids or alatoid nymphs (young aphids that will form wings) have been seen. Due to the cold weather and rain, aphids can be seen below the soil line on the stems, or even underneath the root clusters on seedling Johnsongrass.
