According to the University of Arkansas Cooperative Extension, fall armyworms are one of the most devastating pests of pastures,hayfields and crops with damage appearing almost overnight. Here are a few armyworm scouting tips:
- Diligently scout pastures,hayfields and cropland by examining at least 10 one square foot samples at random across the field.
- Include a few samples in areas of abundant growth because this is where female armyworm moths prefer to lay eggs.
- Chemical control is needed when 3 or more worms per square foot are found. If chemical control is necessary, there are a number of insecticides available for control. It's important to read label instructions before purchasing and follow harvesting and grazing restrictions.
