Seed stacks dominate

GROWERS face a wide selection of seed products for next season. Seed companies recently announced the release of their new 2006 corn hybrids and soybean varieties. Technology traits continue to dominate the market, but companies also are promoting strong agronomic traits. Here's a look at the offerings from several companies.

Dairyland Seed

This West Bend, WI, seed company offers 17 new soybean varieties — eight with Roundup Ready (RR) and STS herbicide tolerance, including Group 0 and Group 1 varieties. The stacked-trait soybean varieties may be used with a tankmix of Roundup and Harmony GT at the expanded use rate. The other new varieties may include Roundup tolerance, extensive soybean cyst nematode protection, and tolerance to Phytophthora, white mold, iron chlorosis and brown stem rot.

Dairyland Seed introduces 21 new corn hybrids, including triple-stack numbers with RR, YieldGard corn borer and rootworm protection, double-stack numbers with RR and YieldGard, and single-trait numbers with RR, YieldGard corn borer and YieldGard rootworm. For more information, visit

Company literature states that in 1,300 field comparisons conducted on the new Asgrow Elite varieties last year, Asgrow yielded 3.5 bu. more per acre than the leading competitors' brands.

The Asgrow brand includes new varieties in many of the maturity groups that may include the RR trait, Phytophthora tolerance, protection against brown stem rot, iron chlorosis tolerance, resistance to soybean cyst nematode and frogeye leaf spot tolerance. For more information, visit

GROWERS PURCHASING Pioneer Hi-Bred hybrids with Poncho seed treatment will receive a new seed-applied Dynasty fungicide with it.

The company suggests using the Poncho and Dynasty protection in reduced-tillage systems and for early planting.

The treatment package of Dynasty fungicide includes Maxim XL fungicide and a new seed treatment polymer to improve seed plantability and to reduce dust-off. The Dynasty-Maxim XL combination from Syngenta supplies a higher level of activity on Fusarium and Pythium.

SYNGENTA SEEDS' new Agrisure corn traits allow growers to plant herbicide-tolerant and insect-resistant hybrids with a full range of assurances that don't limit growers' glyphosate brand selection. Agrisure GT (glyphosate tolerance), Agrisure CB (season-long corn borer protection) and Agrisure GT/CB (a stacked combination of these two traits) will be available in corn hybrids from NK Brand, Garst, Golden Harvest and more than 50 other seed brands.

Agrisure traits are supported by Replant and Trait/Crop Loss Assurances, which protect growers from losses due to poor crop establishment that results in crop replanting or crop loss, and a Trait Investment Loss Assurance, which protects growers from losses prior to planting. Hybrids with Agrisure GT also come with a Volunteer GT Corn Assurance that manages volunteer Agrisure GT corn in the following year's glyphosate-tolerant soybean rotation.

Agrisure traits that will be available in 2006 are:

  • Agrisure GT — provides tolerance to in-crop applications of glyphosate-based herbicides, at even six times the labeled rate.

  • Agrisure CB — controls European corn borer and has tolerance to Liberty herbicide.

  • Agrisure GT/CB — stacks glyphosate tolerance and Bt corn borer protection into a single hybrid.
