Insect Spectrum

Broad-spectrum Control with PowerCore™



European corn borer (ECB) feeds on all above-ground parts of the corn plant. ECB can produce one, two or multiple generations in a single season. First-generation ECB cases whorl damage, while second-generation ECB tunnels through the stalk.


Black cutworm (BCW) is the most damaging cutworm species in corn. Larvae sever plants near the soil line, reducing stands and lowering yields. Damage from BCW is often most evident in no-till or weedy fields, especially in poorly drained areas. Storm systems carry adult BCWs moths to the Corn Belt from the southern United States in April and May each year where they lay their eggs in green fields.


Southwestern corn borer (SWCB) can produce two or more generations per year attacking corn at multiple growth stages. Later generations feed on developing silks and then tunnel into the stalk, leaving the plant more susceptible to lodging.


Corn earworm (CEW) larvae, most prominent in southern geographies, causes damage to corn by feeding on the tips of developing ears, but it is also known to feed on the whorl, silks and tassel. Damage to the ear not only decrease yield potential, but also creates an easy entry point for diseases.


Fall armyworm (FAW) overwinters in the Southern United States and migrates north in the summer. Early generations of FAW feed on young corn, from emergence to waist high or approximately V8, and can destroy entire plants. Controlling FAW with traditional pesticides is difficult and often not economical.





Growers using corn insect protection technology with Bacillus thuringiensis (Bt), including SmartStax, are required to follow Insect Resistance Management (IRM) guidelines by the U.S. Environmental Protection Agency.  

refuge — an area of non-traited plants — is a key element of IRM. Insects in the refuge are not exposed to the Bt insecticidal protein, allowing them to breed with rare insects that naturally resistant to Bt proteins. Susceptibility to the Bt proteins is passed to offspring, helping to protect the durability of the corn trait. More information, including refuge configuration options, is available in the Dow AgroSciences Corn Product Use Guide or go to the IRM refuge calculator, for additional refuge management tips.

PowerCore® technology also is available in a convenient, single-bag solution for refuge compliance through Dow AgroSciences PowerCore Refuge Advanced®.

Growers must sign a formal agreement before the purchase and delivery of seed containing PowerCore technology.  Go to www.traitstewardship.com for more details on the Dow AgroSciences grower agreement and IRM.
