High-tech paper to show the deposition of drops when applying agricultural pesticides.
Handle with gloves, as moisture from your hands stains the paper. The papers are valid for 2 years after the date of manufacture and if stored properly.
Water-sensitive papers should be distributed in the plants/soil as representatively as possible in the target, and it is recommended that each plant canopy be distributed in three extracts: upper (PS), middle (PM) and lower (PI) of the plant, or close to the desired target.
After spraying, you can scan the papers using a scanner and choose a computer program to measure the drops, as well as cell phone applications to process the results, or manually interpret them using a magnifying glass and comparing them with references.
When drops settle on the paper, they produce larger stains, requiring the use of the Correction Factor (CF) to obtain the corrected diameter closest to the real one. To do this, it is necessary to divide the observed diameter by the correction factor contained in the table or through the mathematical regression model below.
This is a high-tech paper used to show the deposition of droplets during the application of pesticides. When the droplets fall on the yellow side of the paper, they show blue spots resulting from the reaction with water. They are easy to use, easy to view and portable. It is recommended to use at least 7 to 10 papers for each field evaluation due to variability.
Water-sensitive papers are sold in sizes of 26 x 76 mm and 52 x 76 mm sold in packages of 25 and 50 units, packaged in aluminum packages with zippers to close after opening. We also have sizes of 26 x 220 mm and 26 x 320 mm in packages of 10 and 20 units.
