 Walking out here in this field, we've only seen one rootworm beetle. He says fungicide treatments have been key. When we spray our fungicide, we'll use a beetle bomb as well just to try to control the adult insects. Lillibridge says conducting soil tests has helped him identify which areas of his farm need the most management. We kind of like being able to test the soil and find the DNA for the rootworms. And if we have DNA present, then we'll treat the soil.
