Armyworm issues

By Ron Hammond, Andy Michel

A few weeks ago we mentioned reports of armyworms in forages and the need for growers to check their stands for signs of insect feeding.  Over the past week or so, this concern has grown considerable, and problems are occurring in rangelands, forages, cover crops including rye, and wheat fields. Not only is Ohio experiencing problems, but numerous Midwest states are reporting similar instances of large numbers of armyworms feeding in fields, especially in newer plantings. An excellent article on the problem is available at the Kentucky Pest News site that was written by our colleague, Doug Johnson, that discusses the problem and answers various questions (http://www.ca.uky.edu/agcollege/plantpathology/extension/kpn/current.html). Until we get a few hard freezes, expect much of this feeding to continue. Make special note of whether armyworm feeding is killing off pasture or forages, or any newly sown planting.  Those plants might still be alive and continue to grow.
