Corn rootworm is still a significant problem in Illinois, especially in continuous corn fields. The pests are known for damaging corn plants' roots, leading to reduced yields and economic losses for farmers.
According to the University of Illinois Extension, corn rootworms have evolved to overcome common control measures, such as genetically modified crops and insecticides. As a result, farmers need to be vigilant in their efforts to manage the pests.
One option for managing corn rootworm is crop rotation, which involves alternating corn with non-host crops like soybeans. This helps to disrupt the pests' life cycle and reduce their numbers.
Another approach is to use integrated pest management (IPM), a strategy that combines various pest control methods to reduce reliance on a single tactic. IPM involves regular scouting for corn rootworm damage, targeted use of insecticides, and planting resistant corn varieties.
The University of Illinois Extension recommends that farmers carefully evaluate their corn rootworm management strategies each year and adjust as needed based on pest pressure, weather conditions, and other factors.
Corn rootworm remains a persistent challenge for Illinois farmers. However, with proper management and a range of control measures, they can minimize the damage caused by these pests and protect their yields and profits.
