Directions for Mixing Agri-Fos & Pentra-bark:  Mix Agri-Fos® with Pentra-Bark® and water in the proportion specified on the label, which yields one gallon of spray: 62.4 oz (1.9L) Agri-Fos® + 62.4 oz. (1.9 L) water + 3.2 oz (95 ml) Pentra-Bark®.  Mix in the following order: water, then Pentra-Bark®, then Agri-Fos®, so that the Pentra-Bark® will dissolve properly in the water and will not precipitate out at the bottom of the sprayer. Gently shake and pour into sprayer.

Directions for Spraying Apply uniformly up 6 - 9 feet of trunk circumference. Spray from top down to ground level from either first branch or from as high as possible without exposing applicator to drift. Spray to just prior to runoff. To avoid waste of Agri-Fos, portions of trunks with moss that is so heavy as to interfere with spray reaching the tree's bark may be brushed to remove excessive moss, or if a relatively small area, may be sprayed around. The solution will likely discolor or kill moss and lichen.  Can be used as a preventative or curative application. Wear protective gear: gloves, mask, long sleeves and pants.  For more info, see “Protecting Your Oak Trees from Sudden Oak Death” at http://ucce.ucdavis.edu/files/filelibrary/1068/39745.pdf.
