How Clean is Your Sprayer? Study Participants Needed

We are currently looking for 30 Nebraska spray applicators for a sprayer cleanout study. The United Soybean Board along with universities across the nation are teaming up to study the effectiveness of sprayer cleanout when applying dicamba. 

The sampling procedure is simple and collection cups will be provided. The goal is to collect basic information about the sprayer, the applicator’s rinsate procedure for dicamba (and other products mixed in the tank), and the subsequent herbicide load.  Participants need to take two 40 ml samples and complete a brief one-page questionnaire. When sampling is finished, we will make arrangements with the applicator to pick up the samples.

This study will help us as application educators know if the information we are sharing is getting to the applicator and proper cleanouts are being done.  We will gladly share the results with the applicator and/or company at no cost later this year. If you would be interested in helping us, we would appreciate it.

To participate, please contact Chandra Hawley at the university's West Central Research and Extension Center in North Platte at 308-696-6741 or
