We found headworms in a milo field near Osborne today. You can generally expect 5% loss per worm per head. A great option to get rid of these pests is Prevathon at 14 oz/acre! It won't kill the beneficial insects that will help control sugarcane aphids should they make their way into your crop.
Healthy sorghum with no indication of headworms. You should being scouting for headworms shortly after the majority of heads have finished flowering.
The purple splotches under the milo head show that headworms are in the plant.
