Find Your Chemical Label
The spray tip selection tools found on this page will only help you if you have the chemical label. Find your label by CLICKING HERE. Please do not continue without.
Always adhere to the precise directions printed on the chemical label you are applying. The chemical label will help you determine the recommended droplet size, application rates, sprayer speed, and nozzle spacing for your specific application. If you cannot find the chemical label in this database, we suggest you consult your local agronomist.
Four key Things

1. Droplet Size

2. Application Rate

3. Sprayer Speed

4. Nozzle Spacing
Droplet Size
- Very Fine sprays are less commonly used because such small droplets are prone to drift unless they are used under special weather conditions or with spray equipment designed for them.
- Fine and Medium are often used for foliar-acting weed control and contact-acting fungicides and insecticides.
- Medium sprays are also often used for systemic-acting fungicides, insecticides and herbicides. Medium sprays are used by default by most applicators when spray quality is not defined by the label.
- Coarse and Very Coarse sprays are often used for systemic and residual herbicides.
- Extremely Coarse sprays are often used for soil-applied herbicides and fertilizers.
Measurement Units
Application Rate
High application rates provide more spray per area and can increase spray coverage of the target but require more frequent stopping to refill the sprayer, reducing the area that can be treated in a day. Lower application rates require fewer stops for refilling but require close management of spray quality to maintain adequate coverage of the target.
Sprayer Speed
MPH = feet x 0.682 ÷ seconds
