Brief Project Summary:

Soybean aphid, Aphis glycines, is a major insect pest of soybeans in North Dakota. This continuing field demonstration project compared different insecticide strategies, seed treatments, foliar applied insecticides using three modes of action (organophosphate, pyrethroid and neonicotinoid), and the aphid resistant soybeans containing the Rag1 gene.

Understanding the producer's risk with different insecticide strategies, host plant resistance and its economics, and pest management of soybean aphid can be optimized for North Dakota's soybean producers.

Final Project Results

Treatments with the Rag1 aphid resistance gene had the lowest CAD among treatments, regardless of location; however, these varieties were Group 1 and did not reach maturity in 2013. As a result, Rag1 varieties are not practical in ND until shorter-maturing varieties are developed with the Rag1 gene.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
