This diagnostic tool is intended for corn producers and especially for individuals with agronomic backgrounds who troubleshoot insect pest problems in corn: extension agronomists, crop consultants and scouts, and agricultural input dealers and.

Corn earworm is also known as the tomato fruitworm or cotton bollworm. This 1- to 2-inch-long caterpillar ranges from light green to purplish brown. Moths lay eggs on corn plants in early summer and larvae feed first on the silks, then on the kernels at the tip of each ear.

The insect can prevent pollination, and it opens kernels to fungus. At other times the impact of pests can be minimized by careful selection of varieties, cultural practices, and conservation of natural enemies (parasites, predators, and diseases) of the pests.

The companion book, Sweet corn grower’s handbook, gives more detailed information on the major diseases, pests (and their natural enemies), and how to manage them in an integrated way. Corn development can be predicted by tracking degree days (DD), which measure heat accumulation based on daily air temperatures.

For example, shoot emergence occurs when approximately DD accumulate after planting. The base temperature for corn development is. This Sweet Corn Pest Identification and Management pocket guide is a quick, colorful, and handy reference for sweet corn growers, extension educators, crop consultants, and industry field representatives who work in the North Central Region and Ontario, Canada.

Field corn is a widely planted crop grown in 48 U.S. states. Different pest complexes occur across the various production regions of North Carolina (Mountain, Piedmont, Coastal Plain, Tidewater).

Recent focuses on mycotoxin levels in corn create a need for both sound agronomic practices and more efficient insect management systems for ear-damaging pests.

Formerly devastating. they prey upon many other insect pests. Application of a soil-applied insecticide or seed treatment for corn rootworm at planting will also suppress these insects, giving the seedling time to establish.

Southern Corn Rootworm The southern corn rootworm damages. Yet, in ecological or organic production of sweet corn, achieving worm-free corn is one of the most difficult challenges.

Managing Insect Pests in Organically Certified Field Corn Organic production of field corn must rely upon three basic strategies for insect management: • Keeping pest populations below threshold levels.

• Making the crop unattractive as possible to invading pests. • Keeping the crop optimally competitive and tolerant of insects as possible. Management of seed and seedling feeding insects. including corn, should be to minimize input costs and crop damage while maximizing profit for the grower.
