The best offense is a good defense when it comes to pest management, especially corn rootworm–an insect impacting more than 31 million acres and costing growers an estimated $1 billion annually in lost yield and control measures. Syngenta agronomists are encouraging growers to start their yield defense strategy now by monitoring for pests such as corn rootworm, western bean cutworm, and corn earworm. Monitoring throughout the growing season can help determine the best management strategies now and for the future. “There are several key insect pest corn growers should keep an eye out for this growing season – including corn rootworm and western bean cutworm,” says Bruce Battles, technical agronomy manager for Syngenta. “For those that plant corn on corn, conditions have supported an increase in corn rootworm populations in the last few years. Conducting root digs and monitoring adult corn rootworm beetles will help guide future management decisions.”

According to Battles, western bean cutworm has continued to move east across the U.S. and into Ontario over the last two decades. “There can be several western bean cutworm larva per ear causing significant damage if it is not controlled.”
To manage against costly pests, a whole-farm defense approach should include a trait stack that controls the widest spectrum of pests. Syngenta‘s DuracadeViptera trait stack offers the industry’s most comprehensive protection, controlling 16 yield-damaging above- and below-ground insect pests, more than any competitive trait stack on the market.
“Some insects, such as corn rootworm, have indicators like previous year beetle counts or roots scores that can help predict next year’s pest pressures and help with management decisions,” says Tim O’Brien, traits manager for Syngenta. “But for other insects, their migrations and pressures can be unpredictable. Therefore, the best game plan against 16 different above- and below-ground insect corn pests like corn rootworm, western bean cutworm and corn earworm is the defense provided by DuracadeViptera.”
