## What is Ground Spray?

The Pesticide Application Technology group at the University of Nebraska-Lincoln ‘s West Central Research and Extension Center (WCREC) in North Platte, NE, is dedicated to investigating aspects of pesticide applications, with emphasis on efficacy and drift. We are utilizing new technologies, including laser diffraction systems in a static chamber, a low-speed wind tunnel and a high-speed wind tunnel, to explore application methods and technologies, such as nozzle selection, adjuvant chemistry, sprayer set up, and wind speed. Our goal is to understand how these factors and others interact to influence spray quality, pesticide efficacy, and drift. 
We have formed close partnerships with both industry and academic collaborators, including Wilbur-Ellis Co., The Aerial Application Technology team within the USDA-ARS, and the University of Queensland, Australia. It is our mission to work with these groups and others interested in maximizing pesticide efficacy and mitigating pesticide drift. We feel that these research efforts are critical to ensuring that yield loss due to pests does not jeopardize our ability to create food, fiber and fuel for a growing world population as well as ensure the health and sustainability of humankind and our environment. 
This application will allow custom applicators and growers the ability to easily predict the spray quality of their application before it is applied. The user can input nozzle type, spray angle, orifice size, spray pressure, and solution and the application will calculate the spray quality based on our research. The user will be able to save these results or e-mail them to another person or company. This application will also give the droplet size spectrum for the various input parameters which will allow the applicator to have a sense of the potential of the spray to drift.
As our research program moves forward, more data points will be added such that any ground applicator can have access to the most up to date information on spray quality.

### 5/5 — Great app for applicators

*2012-11-17*

Looking forward to watching the app grow. Should provide a great tool for applicators to guide their applications.

### 5/5 — Amazing!

*2012-11-17*

Simple to use, and I like the fact I can save or email the spray quality information to myself with a time stamp for my records.

### 4/5 — Nice, easy to use app

*2012-06-29*

Nice interface, easy data entry, useful/relevant results screen. Once more tips and additional spray materials get added this will be a very powerful tool. Nice job!

## Frequently asked questions about Ground Spray

### What is Ground Spray used for?

Ground Spray helps custom applicators and growers predict the spray quality and droplet size spectrum of their pesticide applications before they are applied. This allows for better control over efficacy and potential drift.

### What information do I need to input into Ground Spray?

You will need to input parameters such as nozzle type, spray angle, orifice size, spray pressure, and solution details. The app then uses this data to calculate spray quality based on research.

### Can I save or share my Ground Spray calculations?

Yes, the application allows you to save your calculated results. You can also e-mail these results to another person or company for reference or collaboration.

### How does Ground Spray help with pesticide drift?

By providing the droplet size spectrum for various input parameters, Ground Spray gives applicators a sense of the potential for their spray to drift. This information can help in adjusting application methods to minimize drift.

### Is Ground Spray updated with the latest information?

As the research program moves forward, more data points will be added to Ground Spray. This ensures that ground applicators have access to the most up-to-date information on spray quality.

### What devices is Ground Spray available on?

Ground Spray is currently supported on iPhone and iPod devices. It is designed for users who need to access these calculations on the go.

### How often is Ground Spray updated?

The latest version of Ground Spray is 1.7, which was last updated on January 25, 2017. While it has not been updated recently, the core functionality remains valuable for its intended users.

### Does Ground Spray have ads?
