CORN PESTS

  • Manage Corn Rootworm in 2019

    Understanding the risk of corn rootworm damage in your specific fields will help you make the best management decisions to manage risk and maximize profit in 2017.

  • Black Cutworm and True Armyworm

    Black cutworm and true armyworm presence is sporadic and often field specific. The best way to know what is going on in your fields is to scout for damage. Fields with plant growth during the spring, either from winter annuals or cover crops, are more likely to attract egg laying moths. If damage is detected early a rescue treatment can be used to limit the extent of the damage.

  • Manage European Corn Borer

    Scouting is key to effective European Corn Borer management. Even though the use of B.t. hybrids has been very effective, ECB still pose a significant threat. If the threat is identified at the right time there are still options to protect yield and profit.

  • Early Season Corn Pests & Diseases

    Success starts at planting. Ensuring corn is planted into a favorable environment will maximize its chance of successful germination. Knowing the most susceptible fields will help you focus your scouting program. Timely scouting throughout May and June to detect early signs of pests and diseases will equip you with the information you need to make the appropriate management decision. Small reductions in stand and stunted plants can add up to significant yield reduction. Being aware of what to look for can make a difference in your success.

  • Western Corn Rootworm Resistance and Control Concerns

    We have learned several important characteristics of western corn rootworm (CRW) control from recent reports of severe rootworm feeding on Bt hybrids. These reports either show some CRW resistance developing (Iowa report) or at least severe root damage present on Bt hybrids that are used to control feeding larva (Illinois report).

  • Japanese Beetles Impacting Corn and Soybean Fields

    High populations of Japanese beetles already are occurring across the Midwest corn and soybean production areas. Feeding by adults can be a serious problem in both corn and soybeans. Thus scouting is crucial, especially during the reproductive stages of both crops.

  • Manage and Prevent Palmer Amaranth

    Palmer amaranth is an aggressive, invasive weed that has become the most significant weed pest to soybean and cotton farmers in the southern Corn Belt and southeast United States. In recent years Palmer amaranth has been confirmed in Iowa, Illinois, Indiana, Michigan and Ohio indicating it could become a major agronomic weed in the Corn Belt. While not much focus has been put on specifically controlling Palmer amaranth in Wyffels Hybrids’ marketing geography, it’s clear that proactive planning and control of this weed before it becomes established in your fields and on your farm is warranted.

  • Black Cutworm Management

    There are several species of cutworm in the Midwest, but the Black Cutworm (BCW) poses the biggest threat to young corn. Depending on the size of corn plants, one black cutworm larva can cut up to four corn plants in its lifetime. Early recognition and identification of the problem can help you be more confident, and timely, in making management decisions to protect your yield potential.
