SW 5554GTView more information →
Proven, versatile, performs in presence of disease. Brings additional ear ﬂex and yield stability to silage and grain acres where soil types and conditions vary. Strong eastern cornbelt hybrid. Widely adapted mid-south into New York where the maturity is grown. Good plant size for very high silage yield.
LIMITATIONS: Moves south better than north where dual purpose use is in play. Nice silage ﬁt in the north.
MANAGEMENT: Solid ﬂex ear for wide use on silage acres.
SW 6540GENSS (RIB) & SW 6540GENVT2P (RIB)View more information →
Combines yield, agronomics, health to work in zone and south. This is the go to hybrid for genetic Anthracnose Stalk Rot and Gray Leaf Spot resistance. Good silage performance in the maturity.
LIMITATIONS: No rootworm protection on GENVT2P version.
MANAGEMENT: Above average with fungicide on corn after corn acres.
SW 6601L & SW 6604LRRView more information →
Best leafy genetic platform in maturity for conventional or Round Up® acres. Exceptional north/south adaptation due to unusual early flowering habit for fuller season hybrid. Accumulates dry matter early and grain fills quickly. Proven agronomics for very tall plant type. Combines yield and quality.
LIMITATIONS: Not suitable where there is heavy rootworm pressure.
MANAGEMENT: Moderate populations enable full yield potential. Structured refuge options.
SW 6614RRView more information →
Single trait Roundup® hybrid for any acre except where insect protection is needed. Versatile and consistent across the Eastern Cornbelt with adequate southern movement. Excellent for moderate cost input acres and silage. Simple to manage Roundup® system with no conventional herbicide yield drag.
LIMITATIONS: Not adapted to the deep south, especially coastal.
MANAGEMENT: Consistent silage and grain performer with wide acre suitability. Excellent after soybeans. Structured refuge option.
SW 6630GENSS (RIB)View more information →
SmartStax® hybrid with maximum insect protection package. Versatile, SW 6630 works consistently in high yield environments and stress prone eastern sites. Nice agronomics, late season health, staygreen; protects silage & grain yield. Must plant silage hybrid where rootworm protection is needed.
LIMITATIONS: Fungicide protection may provide additional boost in performance in corn after corn rotations, especially in the Mid-Atlantic, southward.
MANAGEMENT: Nice finishing hybrid for the maturity. Monitor moisture at harvest for silage.
SW 6760GENVT2P (RIB)View more information →
Widely adapted with consistent silage production. SmartStax version brings rootworm control to continuous corn acres. ASR gene for Anthracnose Stalk Rot resistance. Handles medium-high populations. Good ear girth and kernel depth.
LIMITATIONS: Limited supply for 2020.
MANAGEMENT: Better silage option than sister hybrid SW 6780GENVT2P.
SW 6770GENSS (RIB) & SW 6770GENVT2P (RIB)View more information →
Widely adapted, healthy, moves south for silage. Excellent corn after corn. Handles cool soils. Average Gray, excellent Northern Corn Leaf Blight resistance.
LIMITATIONS: Limited ear ﬂex – medium and higher populations maximize silage yield potential.
MANAGEMENT: Use as main season silage hybrid according to insect protection required.
SW 6780GENVT2P (RIB)View more information →
Adapted southern PA to mid-south without east/west limitations. Average/ adequate Gray Leaf Spot tolerance. Resistant to Northern & Southern Leaf Blight.
LIMITATIONS: Adequate for silage in deep south.
MANAGEMENT: Corn after corn with fungicide. This is an “in zone hybrid” that should not be pushed far south of zone.
SW 6999 3000GTView more information →
Consistent high yield silage punch in testing and grower fields. Agrisure® 3000GT trait package with corn borer and corn rootworm protection. Good farm agronomics with excellent late season health. Consistent ear development. Well suited for corn after corn acres. A Mid-Atlantic Gray Leaf Spot option.
LIMITATIONS: Average emergence in cold soils.
MANAGEMENT: Full season hybrid north, wider planting window south, timely planting captures most silage yield.
SW 7000View more information →
Extremely wide eastern adaptation with stress tolerance across soil types. A proven performer, typically outperforming conventional hybrid expectations.
LIMITATIONS: Move to another hybrid for insect protection. Not glyphosate tolerant.
MANAGEMENT: Corn after corn with fungicide. SW 7000 is a structured refuge option.
SW 7559VIP 3110View more information →
Well adapted southern Pennsylvania to Florida and the coastal US. Total package with grain yield, test weight, and agronomics. Good vigor and growth for a late hybrid. Consistently good performance where Gray Leaf Spot is present. Fancy grain near food grade level.
LIMITATIONS: None known for silage.
MANAGEMENT: First choice silage option for Grey Leaf Spot areas.
