Paper

Handling and Storing
By following the guidelines below, the integrity of Water-Sensitive Paper remains intact, which ensures
the accuracy of your results.
Handling
• Be sure to wear gloves when touching the Water-Sensitive Paper to prevent moisture from being
transferred onto the paper.
• Make sure it is dry where you attach the paper. This way the paper will only pick up the spray,
not extraneous water.
• It’s a good idea to photocopy results to allow for later evaluation and record keeping.
Storage
• Water-Sensitive Paper can be stored up to 10 years if it remains in its original package and the
packaging isn’t damaged.
• Once the strips have been used, they must be stored in dry conditions, like an airtight box or bag.
• After exposure, strips can be protected in plastic sleeves or with a thin, clear, adhesive tape
(be sure to apply it without air bubbles).
Water-Sensitive
Paper
An Innovative Solution
Over the past 20 years, Syngenta Crop Protection has developed a way
to monitor spray distribution in your fields to help ensure optimized
application of fungicides, herbicides and insecticides to a variety of
crops and plants. Water-Sensitive Paper is a rigid, yellow paper
designed to turn dark blue when aqueous drops contact it.
Ideal spray
This is an example of an ideal spray.
Coverage and droplet size are even
and consistent, illustrating proper
product coverage.
Improper Application
This is an example of an improper
application. Coverage and droplet size
are not even and consistent, illustrating
improper product coverage and poor
application calibration.
Handling Error
This is an example of a handling error.
Always wear gloves when touching the
paper to prevent transfer of moisture
from your hands to the paper.
This provides an instant visual of the spray distribution
and droplet size, allowing growers to adjust sprayer
settings to achieve optimal spray patterns.
Water-Sensitive Paper confirms the actual
spray pattern on the target surfaces in the field.

A Closer Look – About Water-Sensitive Paper
Aerial Applications Fine Fine Medium Medium Coarse Coarse
Once attached to the plant and contacted by spray droplets, the Water-Sensitive Paper immediately turns a dark blue
color at the impact site. The paper can be used for ground or aerial applications and can be analyzed for uniformity,
area covered, droplet density, and relative droplet size with the naked eye, a hand lens or an automatic image analyzer.
Why Use Water-sensitive Paper?
• Reacts to sprays on contact for immediate results
• Provides a precise record of spray deposition
• Reveals spray pattern uniformity and droplet density
• Provides visual approximation of the spray droplet size spectrum
• Reduces costs by promoting efficient spray levels
• Provides information to increase spray consistency for more uniform plant protection
• Works without the addition of dye or other additives that could influence results
• Measures coverage, droplet density, and relative droplet size simultaneously, giving all necessary
pattern information in one step
In aerial applications, place cards
at six- to nine-foot intervals over a
three-run swath width.

About Droplet Size and Spray Distribution
The ideal amount of coverage varies by the type of application and the product being used. On the following
page, spray application examples are shown for aerial, airblast sprayer and boom sprayer application equipment.
General coverage recommendations are as follows; use label recommendations if different:
• Fine coverage: insecticides
• Medium coverage: post-emergence contact herbicides
• Coarse coverage: fungicides, pre-emergence herbicides
In airblast applications, staple each
end of the paper directly to leaves
at the top, middle and bottom of the
tree, as well as on the sides.

To get the best results from Water-Sensitive Paper, the paper must be correctly applied following the instructions below:
• Number the Water-Sensitive Papers or write their positions on the back so you know where each paper was
during the application. Keep a key to identify starting points.
Boom Spray Applications Fine Fine Medium Medium Coarse Coarse
• When attaching the paper to leaves, apply a piece near the top, near the base and in the middle of the plant or
tree. Also apply pieces on each side at mid-height. This gives the best assessment of where the spray is hitting
and what areas are missed.
• In aerial applications, place paper at six- to nine-foot intervals over a three-run swath width.
• Wear gloves when placing papers on soil or leaves to keep your fingers from applying moisture onto the paper,
and be sure the leaves are dry.
• Staple the paper at both ends so it is securely attached to the leaf.
• Check to make sure the paper has not changed the leaf’s orientation.
• After the application, wait until the paper is fully dried before removal. Also, be sure to wear gloves to
preserve the sample.
In boom spray applications, staple
the paper to leaves or a wooden
lath across a single-run width,
leaving a gap for tractor wheels.
