Army worms

We have worms in our Haymeadow we sprayed them.
What is the timeline of there life cycle and will they hurt cows if they get in the pasture.

Starting to see signs of them…guess pastures are going to get fertilized after all….

Had them many times. Always sprayed with 7 or methal. Tried to keep cattle off until the next day but they didn't always corporate, never had any problems. They usually don't want to graze where the worms have eaten

Here is a chart with what is recommended in Texas with any grazing or harvesting restrictions. Hand written notes are costs per acre

Thanks, BC - something else to keep in mind is most of those pesticides are contact only. Prevalon and Mustang Max have a residual effect. Prevalon is 4 weeks and Mustang Max is 3 weeks. The majority of the rest, including LambaCy are contact only. Which is why in 2018 when they were really bad, many people were spraying every week.
