Corn!įlour corn has soft starchy kernels easily ground into flour. Material controls: Bt kurstaki, Spinosad. Material controls: Bt kurstaki, Spinosad.Įuropean Corn Borer (ECB) and fall armywormĬultural controls: mow and disk old corn stalks into the soil, release trichogramma wasps (found to give better control than insecticides in research by Cornell’s IPM program on five organic farms) for ECB none known for fall armyworm. (Beneficial insects are available at or 80.) Corn Insect Pest ControlĬultural controls: use resistant varieties with tight husks such as Bodacious RM or Silver Queen, choose short-season varieties, release trichogramma wasps. Most sugary enhanced varieties have an optimal picking window of 5–7 days, but some open-pollinated selections hold only 1–2 days. Harvest when the kernels are plump, soft, tender and filled with a milky juice.

Press ears 2' from the tips to assess kernel fullness. Sweet corn is ready 18–24 days after the first silks show, the exact time dependent on the weather in the interim. If you lack sufficient space for enough plants for good pollination, try hand-pollinating by cutting off the tassels and shaking their pollen onto the silks. Plant in blocks of at least 4 rows to ensure adequate pollination, essential for good tip fill. When corn is knee-high, sidedress with azomite or alfalfa meal to stimulate growth. Minimum soil temperature 55°, optimal temperature range 65–85°. Please be patient and wait till soil warms to at least 60° before sowing, or start seedlings indoors and transplant at 3–6' before taproots take off.

Days to maturity are from emergence after direct sowing for transplants, subtract 20 days.Ĭulture: CAUTION: Untreated sweet corn seed will not germinate in cold wet soil.

Seeds per packet vary, open-pollinated selections average 100 seeds/oz, normal sugary varieties 140 seeds/oz, and SE cultivars with shrunken seeds 150-160 seeds/oz.

1 oz packet sows 25 ft, 1 lb sows 400 ft. TripleSweet® Sugary Enhanced: has homozygous se kernels, and 25% of these also contain the sh2 trait. Can be homozygous or heterozygous se with added sh2 kernels. Very tender with long harvest and storage windows. Extra shriveled seed does not germinate well in cool soil. Conversion of sugar to starch occurs at a much slower rate. Supersweet (sh2): 4 to 10 times the sugar content of su and se. The * indicates heterozygous (only one parent contributes the se gene) all others are homozygous (both parents se). Sugary Enhanced (se): more sugar than su, tender kernels & slightly longer storage time. Tend to have high yields and germinate well in cool soils. Sugar converts to starch quickly, so eat them within a few days. Normal Sugary (su): standard varieties with traditional sweet corn texture & flavor.
