HOW TO USE WATER SENSITIVE PAPER
important! To avoid smudging, always handle the paper by the edges. We recommend using the included tweezers and/or wearing gloves (rubber or waterproof) when handling the paper as moisture on your fingers activates the paper.
Important! To preserve its shelf-life, please store the paper in the sealed package when not in use.
Once ready to begin assessing your spray coverage, identify the areas you would like to check and deploy the Paper. Depending on the type of spray application, you can either clip or staple them to branches, leaves or vines; attach them to wooden laths (for field spraying); or for aerial spraying, attach the paper to blocks spaced at intervals of about 1 to 3 meters (3 to 10 feet). It's a good idea to make a note on the back of each card so you can easily identify which card belongs to which location once you collect the cards. After setting the cards in place and spraying the area, wait until the paper is dry, collect and analyze.
- Overdosing: heavily covered paper with no defined droplets, appearance of running liquid
- Underdosing: sporadic, minimal blue specks
- Off-target: paper placed outside the application area should show no droplets
Counting the drops is another simple but more accurate method of evaluating your spray coverage. Below is a sampling of standards you can use for comparison:
- 20-30 droplets per cm2: insecticides
- 30-40 droplets per cm2: contact foliar herbicides
- 20-30 droplets per cm2: pre-emergent herbicides
- 50-70 droplets per cm2: fungicides
