Performance Series


Seminis® Performance Series™ sweet corn hybrids; another innovation that performs all season long.

The Performance Series sweet corn hybrids provide growers with above-ground and below-ground protection from a broad spectrum of corn insect pests which can help growers cut insecticide use by up to 85%. They allow for fewer trips across the field, helping farmers save fuel, reduce greenhouse gas emissions and decrease the carbon footprint per ear of corn grown. Performance Series hybrids offer improved in-crop weed control with tolerance to Roundup WeatherMAX® and Roundup PowerMAX® agricultural herbicides. The Performance Series sweet corn hybrids offer protection with dual modes of action for the following above-ground insects; fall armyworm, corn earworm, European corn borer, southwestern corn borer, sugarcane borer, common stalk borer and southern cornstalk borer, as well as these below-ground insects; western corn rootworm larvae and northern corn rootworm larvae. Additional information can be found in Bayer's Technology Use Guide.

Growing Tips

Can be sprayed with Roundup brand agricultural herbicide.

Roundup WeatherMAXRoundup PowerMAXPerformance Series™ sweet corn varieties are the only fresh market sweet corn products featuring the unique weed control benefits of Roundup WeatherMAX® and Roundup PowerMAX® agricultural herbicides. Be sure to read the label and confirm that the chemical you are spraying is 100% glyphosate with no other active ingredients.


Plant seeds 8 - 12 inches apart on 30 inch rows to achieve optimum yield. Seed depth should be ¾” - 1½” depending on soil conditions, and genetic type. Plant when soil temperature is 60º F plus. Planting in blocks will also help increase uniformity in pollination.

Be sure to read the block on Managing Insects in sweet corn on the following page. Also take a look at our “Insect Scouting Resources” on page 38. Scout field every 7 days to check for insect, weed, and disease pressure. For identification of weeds, insects, and diseases consult your local extension office or view the Midwest Vegetable Production Guide.


For all high quality sweet corn varieties, maintaining an isolation is required to protect the high sugar and flavor characteristics of the sweet corn as cross pollination from other types of sweet corn or from different types of corn will result in starchy kernels.

SE/Synergistic types and SH2/Improved Super Sweet types should be isolated both from each other and from other types of corn including field corn, popcorn and ornamental corn.

An isolation can be achieved either by distance or by a difference in maturity. Preferable isolations would require 700 – 1000 feet distance from other corns, or 10 – 14 days difference in maturity between varieties.

Relative Maturity

Sweet corn maturities are publicized as days to relative maturity. This information comes from supplier data, as well as our trial observations in the Midwest. Prolonged excessive heat or cool temperatures can cause maturity dates to fluctuate to some degree . Monitor your crop through the growing season in order to pick at optimum freshness.


Harvest sweet corn when the end kernels of the ear feel developed. Approximately 21 - 25 days after half silk. Sample sweet corn to ensure quality.


Pre-cool cob temperature to 50ºF. After pre-cooling store at 34ºF and 95% humidity.
