Evaluation of New and Emerging Products for Management of SCN

The goal of this ongoing research is to evaluate new and emerging products that are either marketed as, or have otherwise shown promise for, reducing SCN (soybean cyst nematode) reproduction and/or increasing the growth and productivity of SCN-infested soybeans in Iowa.

To this end, these products are have been and continue to be evaluated throughout Iowa. Plots are 4 rows, 30 inch spacing, 17 ft long. Tested products are applied according to the manufacturer provided instruction. Ten soil cores are collected from the center two rows of each plot in the spring, to verify the presence of SCN in each plot, and again in the fall, to determine if the tested products have an effect on reproduction of the nematode throughout the growing season.

Compounds Tested (Click on product name to see results):

  1. Deny (2002)- a biological control applied as a liquid in-furrow.
  2. Gusto (2004, 2005) - a bacterial spore seed treatment.
  3. Messenger (2002, 2003, 2004) - harpin protein applied as a foliar spray.
  4. MicroCN (2002, 2003, 2004) - micronutrients and biological control broadcast as a liquid and incorporated.
  5. NViro Soil (2002, 2003, 2004, 2005) - composted municipal sewage sludge, broadcast applied as a dry product and incorporated.
  6. ProsperNema (2002, 2003, 2004) - beneficial fungi broadcast applied as a liquid suspension and incorporated.
  7. XCyto (2002, 2003, 2004) - plant hormones (cytokinins), applied either as liquid in-furrow or as broadcast and incorporated.

This research was funded, in part, by Iowa soybean checkoff funds through a grant from the Iowa Soybean Association.
