Cooke County Farmers and Ranchers,
Well its been hot and dry lately! Quite a change from all the rains and flooding received in May and June. With rain expected in some areas in North Texas on Wednesday and possibly this weekend, fall army worms infestations may develop in pastures and hay-fields. Here is some great information from our Extension Entomologist, Dr. Allen Knustson, at our Dallas Research Center, on management of fall army worm in pastures and hay and an updated list of labeled insecticides.
A new addition to the list is Besiege insecticide from Syngenta. Besiege is a mix of Prevathon and lamda cyhalothrin and is labeled for both fall army worm and grasshoppers in pastures and grass grown for hay.
I hope this information is helpful. Let me know if you have any questions or concerns.
