Brief Project Summary:

Indiana soybean farmers depend on herbicides (specifically glyphosate) to control the number one pest in soybeans - weeds. Effective herbicide treatments require attention to factors that influence efficacy such as product selection and rate, equipment calibration, and application timing. However, one factor that is routinely ignored is the quality of the water used to spray the product.

Water comprises about 99% or more of the herbicide spray solutions that are applied to soybeans. There is a fairly substantial body of knowledge regarding the effect of hardness and pH on glyphosate (Roundup) efficacy. However, little is known about the effect of water quality on 2,4-D, dicamba, and...

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.
