The Spraying System Water Sensitive Paper is yellow in color and is stained blue where it is exposed to aqueous spray droplets. This paper is an excellent tool used to evaluate spray distributions, swath widths, droplet densities and penetration of spray. It is a rigid paper with a specially coated yellow surface. It was developed for field use for quick evaluation of sprays. Simple to use: just place the papers in the target area before spraying. After it has been sprayed, allow it to dry and check the droplet pattern.
Using too much spray is a waste of spray and can be harmful to your crops. Not using enough can be a waste of time.
