Corn rootworms can reduce yields by up to 50% and cause up to $2 billion dollars in damage.
Erica Strittmatter with Bayer says the pest feeds on nodal roots found within the root crown. “What we know about corn is that the main nutrient uptake comes from those nodal roots,” she says. “And that nutrient uptake of those critical in P&K nutrients is what helps establish yield for each of those corn plants.”
She tells Brownfield that can cause problems later in the growing season.
