As reports of fall armyworms continue across Tennessee, an entomologist with the University of Tennessee Institute of Agriculture encourages residents to monitor their land for this migratory pest.
"Fall armyworms travel north from Texas, passing right through Tennessee and neighboring states every year," says Midhula Gireesh, assistant professor and UT Extension entomologist. "With the number of reports we are seeing, landowners should regularly 'scout' their property for signs of an infestation, especially these next few weeks."
Gireesh says one of the first indications is grass with a "frosted" appearance resulting from newly hatched armyworms eating the underside of the plant leaf. Other signs include dead plants, brown patches in lawns and even large congregations of birds gathering to eat the worms.
"It is important that we scout every few days to identify infestations quickly. If armyworms are present, it is recommended that you begin control strategies immediately," says Gireesh.
Available at farm supply and lawn and garden stores, chemical treatment options can effectively eliminate most infestations. However, these solutions are not preventative measures and should only be applied if worms are already present. Many insecticides could also pose a risk to beneficial insects and other organisms, Gireesh encouraging applicators to always follow the label and to contact your local UT Extension office prior to application if you have any questions.
