Brief Project Summary:

Japanese beetles have become an annual problem for soybean producers in Illinois. Existing thresholds are based solely on defoliation of the plant, a very subjective measure. A preliminary economic threshold of one Japanese beetle per soybean plant has been proposed based upon previous caged experiments conducted by the principal investigators. Validation of this threshold in real field situations is necessary to reduce or eliminate the possibility of making recommendation to not control Japanese beetle on soybean, when in reality a pesticide treatment was needed (a Type II error). Previous attempts to validate this threshold have been in vain, due to low infestations of Japanese beetles...

Final Project Results

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.
