Nf00-411 Seed Treatment Fungicides For Soybeans (Revised January 2004), Loren J. Giesler
University of Nebraska-Lincoln Extension: Historical Materials
The most common soybean disease problem in Nebraska is seedling damping off and seed rot caused by several fungi. Early season damping off and root rots are often followed by premature death, which in many instances may be attributed to fungal infections earlier in the season.
This NebFact discusses the seed treatment fungicides for soybeans. These includes protectants (contacts) that are effective only on the seed surface; and systemic fungicides that are absorbed by the emerging seedling, which inhibit or kill the fungus inside host plant tissues.

The soybean stand looked horrible late that May. The field had a good seed bed at planting, but rain after planting crusted the soil over the seed furrows. Rain was in the short-term forecast. All other row crops were planted and looked fine, but this field concerned the producer. Should the producer replant? Recommended soybean seeding rates, stand assessment and replanting rates based on Nebraska field research are addressed in this NebGuide.

One of the key issues surrounding the use of Bt transgenic corn hybrids is resistance management. These corn hybrids have been engineered to produce a version of the insecticidal protein from the naturally occurring soil bacterium, Bacillus thuringiensis (Bt), that is toxic to European corn borers and a few other insects.
This NebFact discusses the important principles of resistance management for European corn borer and Bt corn and refuge considerations.
