We are picking up fall armyworms in whorl stage grain sorghum. Most of these infestations are spotty across the field with about one worm per whorl in spots of about 10-20 plants. While plants may look rough, plants should recover with no significant yield loss. It generally takes several worms per whorl to cause enough damage to result in yield loss. If a field is at treatment level, Blackhawk, Prevathon, Besiege, Belt or Lannate would be recommended for control. Consult MP144 Insecticide Recommendations for Arkansas for a complete list of recommended insecticides and rates. Fields that have reached grain fill should also be watched closely for fall armyworms and other head feeders such as corn earworm and sorghum webworm. Treatment level for corn earworm and fall armyworm is one worm per head. Treat for sorghum webworm when five to six per head are found. Once again, Lannate, Prevathon, Besiege, Blackhawk or Belt would be the products of choice. However, if sugarcane aphid is in the field, or potentially a threat, use an insecticide that is soft on beneficial insects such as Blackhawk. Stay away from harsh materials like Lannate or Besiege in order to avoid flaring aphid populations.
