Rootworm damage quickly adds up


It doesn’t take long for corn rootworm damage to add up, says Sean Evans, Monsanto technology development representative for insect management. Evans says under low to moderate pressure, growers have can lose as much as 10 bushels per acre from corn rootworm feeding. Under heavy pressure, losses can tally as high as 30 to 40 bushels per acre up to 50% of potential yield.
